Redox Signaling is Essential for Insulin Secretion
Authors: Ježek Petr , Holendová Blanka , Jabůrek Martin , Tauber Jan , Dlasková Andrea , Plecitá-Hlavatá Lydie
Published: June 2021

In this review, we place redox signaling in pancreatic β-cells to the context with signaling pathways leading to insulin secretion, acting for example upon the action of incretins (GLP-1, GIP) and the metabotropic receptor GPR40. Besides a brief description of ion channel participation in depolarization/repolarization of the plasma membrane, we emphasize a prominent role of the elevated glucose level in pancreatic β-cells during glucose-stimulated insulin secretion (GSIS). We focus on our recent findings, which revealed that for GSIS, not only elevated ATP synthesis is required, but also fundamental redox signaling originating from the NADPH oxidase 4- (NOX4-) mediated H2O2 production. We hypothesized that the closing of the ATP-sensitive K+ channel (KATP) is only possible when both ATP plus H2O2 are elevated in INS-1E cells. KATP alone or with synergic channels provides an element of logical sum, integrating both metabolic plus redox homeostasis. This is also valid for other secretagogues, such as branched chain ketoacids (BCKAs); and partly for fatty acids (FAs). Branched chain aminoacids, leucine, valine and isoleucine, after being converted to BCKAs are metabolized by a series of reactions resembling β-oxidation of FAs. This increases superoxide formation in mitochondria, including its portion elevated due to the function of electron transfer flavoprotein ubiquinone oxidoreductase (ETF:QOR). After superoxide conversion to H2O2 the oxidation of BCKAs provides the mitochondrial redox signaling extending up to the plasma membrane to induce its depolarization together with the elevated ATP. In contrast, experimental FA-stimulated insulin secretion in the presence of non-stimulating glucose concentrations is predominantly mediated by GPR40, for which intramitochondrial redox signaling activates phospholipase iPLA2γ, cleaving free FAs from mitochondrial membranes, which diffuse to the plasma membrane and largely amplify the GPR40 response. These events are concomitant to the insulin release due to the metabolic component. Hypothetically, redox signaling may proceed by simple H2O2 diffusion or via an SH-relay enabled by peroxiredoxins to target proteins. However, these aspects have yet to be elucidated.
From Eco to Sustainable Tourism, the Contradictions and Challenges of Nature-Based Tourism: The Case of Polar Cruises
Authors: A. Grenier Alain
Published: June 2021

Polar tourism includes all leisure travel products set in the Antarctic and Arctic regions. As such, it is conditioned by an interest for nature in extreme settings (polar desert, cold climate, harsh travel conditions – when by sea. The Arctic adds an additional interest for indigenous cultures. Trying to met those tourism interests, a specialized cruise tourism branch developed in the late 1980s (thu sporadic cruises were held back from the XIXth century onward) providing exclusive access the most difficult and far distant latitudes of the High Arctic and opposite Antarctic coastline. In any form of tourism, operators must protect the resources their economic activities rest upon as any deterioration they suffer will sooner or later impact the experiente and its viability. Hence a paradox: how to protect the ecological (and cultural) integrity of these features for sustained competitiveness? Since its emergence, as an industry some 40 years ago, the polar cruising has followed trends in environmental and social management, referring in their marketing and travel policies to both eco- and sustainable tourism. Serving the wealthy customers, initially the well traveled elderly, the ship-based polar industry kept a simple programme of lecture and soft-oriented activities, namely inflatable cruising in icy bays and close-to-shore trekking. Yet, with an increasing clientele of younger middle-age tourists, operators have also diversified their excursion products to offer more sportive-oriented activities off-ship. As long as these activities were non-fuel based, the operators enforced their ecological management claims. But with more fuel-based activities (helicopter, Zodiac sightseeing), and therefore a more invasive approach to the sensitive ecosystems visited, can this industry continue to claim to be sustainable? Based on the sustainable claims made by two important polar cruise operators, this study ams to underlines that while the polar cruise industry, as a whole, might seek to improve its ecological footprint, there remains many contradiction between their will to be environmental and the desire to conquer the environment.
A Review of Alternative Marine Fuels

Published: June 2021

Today, ships navigating all around the world are not allowed to emit SOx more than 0.5%. Same regulation for nitrogen has already come into force. More and more nations are becoming aware and concerned about the negative effects of climate change, whereas many countries are already feeling the effects of harmful greenhouse gas emissions. Therefore, the world’s fleet needs a new fuel types, which are alternative to conventional petroleum-based ship fuels. Benefits such as low sulphur standards accompany all alternative fuel options. As will be discussed further in Section 2, there are challenges and limitations associated with CO2 emissions along with benefits. The review of the literature and field shows that the impact of these current choices on the management and environments is still not bright enough, although each alternative has consisted entirely different effects in their body and each alternative pose specific risks to the environment, crew, management and port states. This chapter gives a review on the impact of each alternative fuels on the environment. In addition, the chapter touches upon handling of risks associated with alternative fuels and technologies.

Published: June 2021

In the Conventional laboratory or industry heating technique involve Bunsen burner, heating mental/hot plates and electric heating ovens. To produce a variety of useful compounds for betterment of mankind, the Microwave Chemistry was introduced in year 1955 and finds a place in one of the Green chemistry method. In Microwave chemistry is the science of applying microwave radiation to chemical reactions. Microwaves act as high frequency electric fields and will generally heat any material containing mobile electric charges, such as polar molecules in a solvent or conducting ions in a solid. Polar solvents are heated as their component molecules are forced to rotate with the field and lose energy in collisions i.e. the dipole moments of molecules are important in order to proceed with the chemical reactions in this method. It can be termed as microwave-assisted organic synthesis (MAOS), Microwave-Enhanced Chemistry (MEC) or Microwave-organic Reaction Enhancement synthesis (MORE). Microwave-Assisted Syntheses is a promising area of modern Green Chemistry could be adopted to save the earth.

In West Lampung, Sumatra, Indonesia, tropical volcanic residual soils are formed from weathering of volcanic breccias in hydrothermal alteration areas with a thickness of up to 20 m. This soil has the characteristics of clayey silt, low to high plasticity, brownish-red color, has the potential to swelling, easily eroded, and slide when it is saturated, and contains the minerals kaolinite, halloysite, illite, dickite, nacrite, montmorillonite, despujolsite, hematite, and magnetite. The results showed that this soil can cause corrosion of steel and is widely used by the community as a medium for growing plants and vegetables and as a foundation for infrastructure (for example, houses). The volcanic residual soil of the research area had Low Rare Earth Element (LREE) potential and specific uses. The soil with characteristic low plasticity has Liquid Limit (LL) brine value <50% will be suitable for agriculture purposes, building foundations, and earth construction. At the same time, the other category is soil with intermediate to high plasticity characteristics, which has an Liquid Limit (LL) brine value >50%, was more ideal for the primary forest.

Published: June 2021

Dementia with Lewy bodies (DLB), the second most common cause of dementia, remains a difficult condition to accurately diagnose and manage. Variable involvement of motor and cognitive functions, plus psychiatric and behavioral symptoms, contributes to the difficulty in managing DLB. Additionally, DLB can cause severe sleep disruption through REM sleep behavior disorder, autonomic symptoms, disruptions of olfaction/taste and mood, hallucinations, and more. In this chapter, advances and remaining challenges in the diagnosis of DLB are discussed, including a review of the current consensus criteria for DLB. The spectrum of disorders with Lewy bodies (LBs) are described including their wide-range of clinical presentations and overlap with Alzheimer’s disease (AD) and Parkinson’s disease with and without dementia. Particular consideration is given to advancements in quantification of cognitive fluctuations through improved clinical instruments, EEG, and other advanced biomarkers. Detection of DLB has improved, but establishing the “primary” pathology in cases with concomitant LB andd AD remains difficult. Likelihood of a clinical DLB syndrome is thought to be a function of distribution of LBs and severity of AD-type pathology. Further work is needed to better understand LB disease subtypes and the underlying pathophysiological mechanisms to allow for more targeted and comprehensive therapies.

Published: June 2021

Palm oil clinker (POC) is a waste from the production process of palm oil, a hard and porous materials. Many studies have focused on the effect of POC use on strength while this study discusses the ability of POC in concrete to absorb sound and its relationship with concrete properties. The study was done by replacing natural river sand in stages of 25, 50, 75 and 100 percent in a mixture of 1: 4 (cement: sand). Sound absorption coefficient (SAC), strength and physical properties affect the SAC were measured. Although POC significantly reduced the compressive strength but all specimens poses good strength more than 5 N/mm2. An interesting result is that POC reduces interconnected porosity and total porosity when replacement is 100% but increases interconnected and total porosity when replacement is between 50 and 75%. SAC at 315 Hz was found has good relationship with percentage of POC and density. It is obtained that POC 50% yield good strength and sufficient SAC that can address the middle frequency range problem, thus can be further suggested to be used for masonry block application for noise control materials.
Hegelian Heritage and Anti-Racist Horizons
Authors: Tangorra Manuel ,   Philosophy Documentation Center
Published: June 2021

The task of confronting Hegel with the conflicts of our present proves to be indispensable to keep alive the critical scope of dialectics. In a context marked by a new wave of movements that challenge the racist structures that inform our societies, the question of the contribution of Hegelianism to an anti-racist thought takes a significant relevance.The hypothesis of this article argues that it is possible to distinguish two different operations that shape an anti-racist critique with the resources of Hegelian dialectical thought. The first one is constituted by the exegetical practice aiming to identify, within Hegel’s own discourse, a speculative core that allows the definitive overcoming of all ethno-racial particularisms through the postulation of a normative universal horizon. Such interpretative perspective, shared by numerous scholars, seeks the absorption of Hegel’s racist and Eurocentric assertions in the larger and global scope of his system. Once the limitation of this option is shown, we will examine an alternative operation, namely, the rewritings of the dialectical thought in certain philosophical reflections arising from the concreteness of anti-racist movements. To that extent, we will revisit the proposals of W.E.B Du Bois and Frantz Fanon as peripheral enunciations of the dialectic that enable a new understanding on the subjectivation processes and liberation horizons of racialized communities.
De minimis state aid
Authors: Jovanović Nebojša
Published: June 2021

In this paper the author analyses de minimis state aid as an exception from the principle of prohibiting the state to help some undertakings in order not to privilege them among other undertakings and to violate their equality on the market. Author explains the notion of de minimis aid, justification of this exception from the prohibition of granting the state aid, privilege that its provider and beneficiary enjoy in comparison with other types of allowable ("compatible") state AIDS, as well as the methods of preventing the circumvention of rules about its granting. Th e author compares the rules of European Union and Serbia in this question, pointing to differences between them. Th e conclusion is that Serbia regulates de minimis aid superficially and vaguely, with important deviations from the EU law. Besides, author contemplates the adequacy of the EU allowable sum of de minimis aid within Serbian economic conditions.

Published: June 2021

This paper presents the results of the conducted research of the health status and seed yield of the dendrological species in five parks situated in areas with different degrees of pollution. According to the volume of seed yield, selected trees in SIV Park had the lowest yield, somewhat higher yield were displayed by the trees in Banovo Brdo Park, then Pioneer Park and Topčider Park, whereas the most abundant yield was that of the trees in Academic Park. On the other end, as per visual assessments of the health state, the trees in Pioneer Park showed the best health condition, the second-best had the trees in SIV Park (air pollution zone), then the trees in Topčider Park and Banovo Brdo Park, while the lowest average score was assigned to the trees in Academic Park. Results of the conducted research suggest that the condition of dendrological plants in these parks is significantly dependent in the protection and care measures taken.

Published: June 2021

We strive to live in a healthy environment and to keep the entire food chain unpolluted and free of all unwanted contaminants. The care for humans cannot be considered partially if at the same time we do not succeed in a fight for unpolluted environment for flora and fauna. Likewise, we need to be well aware of environmental conditions and benefits they provide us with for better quality and healthier living in a particular area. Certainly, each territory has its own characteristics caused by environmental conditions. In geological terms, the territory of Novi Pazar is special in its characteristics since in this area Vardar zone faces Dinaric zone, where both have an impact on the quality of the environment. Knowing the property of parent material that by its dissolution it gives elements which reach lithosphere, hydrosphere and atmosphere and through the food chain they circulate from plants, animals to humans, it is necessary to intensify the study of the properties of geological substrate as an indicator of preserved and healthy environment.

Published: June 2021

The paper presents the results of survey, dedicated to synthesis of metal oxide coatings on porous materials applied for implant surgery (stainless steel 12X18H9T, titanium alloy and high-purity niobium VT5). This article examines kinetic features of electrochemical formation of anodic oxide coatings on steel, niobium and titanium. It is shown that for steel anodic treatment method does not provide a reliable surface passivation (no current decay, the surface indicates the transition to the passive state).Analysis of polarization dependences obtained on niobium and titanium in electrolytes with an activator (F-), indicates surface passivation (current slump), and at potentials above 2 on the surface of a transition curves in transpassive state (as evidenced by the current increase). Consequently, it can be concluded that presence of F- results surface activation of titanium and niobium electrode (F- oxide reacts to form water-soluble complexes) that promotes nucleation and formation of pores of the porous structure of the oxide coating.SEM results verify the presence of self-organized porous oxide film synthesized on titanium and niobium in solutions containing F-.
EL DESARROLLO TURÍSTICO EN LAS ISLAS VERDES DE CANARIAS: EL CASO DE LA ISLA DE LA PALMA (2000-2019)
Authors: Martín Fernández Carlos S.
Published: June 2021

La isla de La Palma (Canarias), una de las denominadas como Islas Verdes, ha mantenido históricamente una apuesta por un modelo económico basado en la actividad agraria de exportación. En las últimas décadas, ante la amenazante desaparición de la protección institucional a su principal cultivo (el plátano), ha variado su estrategia activando la actividad inmobiliario-turística como estrategia de desarrollo. Un cambio que acontece en una coyuntura poco oportuna, al coincidir con un marco institucional regional que controlaba el incremento de la oferta turística. El relato de las contradicciones institucionales acaecidas constituye el objeto de este artículo.

The island of La Palma (Canary Islands), one of those called Islas Verdes, was historically maintained an economic model based on agricultural export activity. In recent decades, in the face of the threatening disappearance of institutional protection to its main crop (the banana), it has varied its strategy by activating real estate-tourism activity as a development strategy. A change that is at a timely juncture, in the same way as it coincided with a regional institutional framework that controlled the increase in the tourist offer. The story of the institutional contradictions that occurred is the subject of this article.

Development and Validation of Work Environment Services Scale (WESS)
Authors:   CMS Business School, Jain University, Patrick Harold Andrew , Kareem Jacqueline ,   Jacqueline Kareem School of Education, Christ University
Published: June 2021

Purpose: This study presents a nine-factor, 32-item measure of work environment scale in the service sector. A healthy work environment is one in which employees trust the people they work for, have pride in what they do, and enjoy working with the people (Levering and Moskowitz, 2004). Methodology: This instrument builds on the conceptual model espoused by Insel and Moos (1974), Gordon (1973), Fletcher and Nusbaum (2010), Amabile et al. (1996), and Spector (2003). The scale included items elicited through a literature review, the use of the Delphi technique with a panel of experts, and tested on 824 full-time employees from nine service sector industries and five major cities in India. Findings: The Work Environment Services Scale (WESS) is a reliable and valid scale useful for measuring the nine work environment factors in the Indian services organization, with its own norms and a detailed manual. Originality/Value: The prevailing scales for measuring work environment do not capture the influence of ethics, recreation facilities, and the impact of social giving on the work environment. Most scales were suitable for sectors in the Western context, and there were no Indian scales measuring service employees’ perception of their work environment.
Musical symbols of good and evil in “Psalms of Repentance” by Alfred Schnittke
Authors: Shirieva Nadezhda Velerovna
Published: June 2021

This article is dedicated to determination of the system of musical-expressive means used by Alfred Schnittke to symbolically reflect the ethical opposition of good and evil in the “Psalms of Repentance”. The relevance of this research is substantiated from the perspective of heightened attention of the composers of the XX century to the musical symbolism that replaced programmability. The study is based on the method proposed by E. M. Akishina for determining the symbols of good and evil in different layers of timbre and texture arrangement of instrumental compositions of A. Schnittke. Application of this method to “Psalms of Repentance” for a cappella choir allows tracing the manifestation of these symbols on the timbre, phonism, melodic arrangement, musical language, and composition. The novelty of this article consists in the fact that unlike instrumental music of A. Schnittke, his compositions for a cappella choir are viewed from such analytical perspective for the first time. The following conclusions were made: the choral and instrumental compositions of A. Schnittke contain a ramified system of musical-expressive means, which clearly distinguishes the symbols of good and evil;  these symbols outline the logic of dramatic development of each part of the “Psalms of Repentance”; their interaction within the framework of general concept of the cycle contains the ultimate ideological message – human choice, which determines his path along the line of sin as eternal Evil or through repentance – on the way towards God as the highest Good.

Making the Case for Suicide Risk Screening in Outpatient Podiatry Patients: An Opportunity for Injury Prevention
Authors: Spector Adam K. , Mournet Annabelle M , Snyder Deborah J , Eastman Emmanuella , Pao Maryland , Horowitz Lisa M
Published: June 2021

Background: Despite prevention efforts, suicide rates continue to rise, prompting the need for novel evidence-based approaches to suicide prevention. Patients presenting with foot and ankle disorders in a podiatric medical and surgical practice may represent a population at risk for suicide, given risk factors of chronic pain and debilitating injury. Screening has the potential to identify people at risk that may otherwise go unrecognized. This quality improvement project (QIP) aimed to determine the feasibility of implementing suicide risk screening in an outpatient podiatry clinic and ambulatory surgical center. Methods: A suicide risk screening QIP was implemented in an outpatient podiatry clinic and ambulatory surgical center in collaboration with a National Institute of Mental Health (NIMH) suicide prevention research team. Following training for all staff, patients ages 18 years and older were screened for suicide risk with the Ask Suicide-Screening Questions (ASQ) as standard of care. Clinic staff were surveyed about their opinions of screening. Results: Ninety-four percent of patients (442/470) agreed to be screened for suicide risk and nine patients (2%; 9/442) screened non-acute positive; zero for acute risk. The majority of clinic staff reported that they found screening acceptable, felt comfortable working with patients who have suicidal thoughts, and thought screening for suicide risk was clinically useful. Conclusions: Suicide risk screening was successfully implemented in an outpatient podiatry clinic. Screening with the ASQ provided valuable information that would not have been ascertained otherwise, positively impacting clinical decision-making and leading to improved overall care for podiatry patients.

Introduction: Geriatrics and widows are neglected in the society. Geriatrics are seen as unproductive. Widows, on the other hand, are humiliated traditionally by their husbands’ family members and community. They face surmounting problems which shadow their urge to seek medical attention. 

Aim: To determine the burden of Ear, Nose and Throat (ENT) and medical diseases in Geriatrics and Widows through identification of common ENT and medical conditions in them.

Methods: This was a 7months prospective study from September, 2017 to April, 2018. The study centers were Dagomo foundation home for the elderly in Benin City and St. Benedict Catholic Church, Obiaja in Edo central. Total population sampling technique was used. All the elderly and widows who gave consent to the study constituted the sample size. Health talk was given; history taking, Ear, Nose, Throat and general body examinations were done. Data on the disease burden identified were recorded. Those that needed further evaluation and management were referred accordingly. Data was statistically analyzed with SPSS Version 20. P value < 0.05 was considered statistically significant.

Result: 50 geriatrics and 67 widows participated. Age ranged 60 – 90 years (mean age of 69.50±7.78years) and 36 – 85years (mean age of 59.61±9.36) for Geriatrics and widows respectively. Geriatrics were 13 males and 37 females while widows were 67. Seventeen (17) different ENT diseases were identified in Geriatrics while 7 ENT conditions and 12 medical conditions were identified in the widows. Predominant ENT diseases were Otitis Media with Effusion (34.9%), Left Cerumen Auris and Otomycosis in similar proportion (20.9%) in Geriatrics. Right Cerumen Auris predominated in widows (65.6%) followed by Left Cerumen auris (50.0%) and Otitis Externa (28.1%). Osteoarthritis was the commonest medical condition (90.6%) in widows. Tests of association were not statistically significant.

Conclusion: There is significant burden of Ear, Nose, Throat and medical diseases in the Geriatrics and widows.

Recommendations: Government should plan specialist healthcare measures to improve the quality of life of geriatrics and widows.

Government should ensure an educational policy to develop age-appropriate training protocols for children and young adults on the challenges associated with aging.

The Department of Agricultural Extension (DAE) is considered as the most prominent public organization in Bangladesh for disseminating agricultural information to the farmers. In this line, the objectives of this study were to determine the extent of effectiveness of DAE regarding their services for improving farming skill and to determine the factors affecting the effectiveness of DAE services. Data were collected from two villages of Nawabganj Upazila (sub-district) in Dinajpur district using structured interview schedule. Descriptive statistics and linear regression analysis were done to explain the data. The findings revealed that majority (70.2 %) of the farmers think that the DAE services are moderately effective for improving farmer’s skill. Among the rest of the respondents, 7.7% and 22.1 % were commented as less and high effective category respectively. The inferential analysis revealed that farmers' education, organizational participation, cosmopoliteness and time spent in farming had positive and significant contribution with effectiveness of DAE services. This means that the initiative for higher these factors would increase the effectiveness of DAE services.  The extension personnel, development practitioners and other researchers may be benefited from the findings. The policy makers should also consider these important factors to increase the effectiveness of DAE regarding agricultural advisory services.

Aims: This paper studies the determinants of Islamic banking profitability and liquidity in the United Arab Emirates (UAE) and Tanzania. It was comparative study. The study gives empirical comparisons between Islamic banks in United Arab Emirates (UAE) and Tanzania in their performance bases.

Study design:   This study covers the samples of five (5) Islamic banks where by two (2) banks from Tanzania that are People Bank of Zanzibar in Islamic branch (PBZIB) and Amana Islamic bank (AIB).  In the side of United Arab Emirates (UAE) three (3) Islamic banks were selected which includes   Dubai Islamic Bank (DIB), First Abu Dhabi Bank (FAD) this is not an IB and Emirates Islamic Bank (EIB).

 The study used secondary data of selected variables which employing panel data for the period of ten (10) years from 2010- 2019. Due to data was on panel bases which includes the two independents variables.

Methodology: To calculate profitability, the Return on Assets (ROA) was used and in liquidity in IBs deposit ratio (LDR) used to measure the liquidity .The study uses descriptive statistical analysis, correlation, multiple regression analysis for two equations according to settled objectives. The three macroeconomic variables were selected that are Gross Domestic Product per capita (GDP), inflation (INF) and exchange rate (EXCH). An autoregressive distributed lag (ARDL) model was applied because the result becomes mixed in the unit root test.

Results: The findings reveal satisfactory evidence that all selected variables are statistical significance in long run relationship except inflation in UAE. The outcomes of the study indicated that selected macroeconomic variables (GDP per capita, Inflation and exchange rates have a major 5% effect on bank profitability and liquidity in Tanzania and the United Arab Emirates.

Conclusion: The study therefore recommends the Tanzania Islamic banks should adopt several policies in order to control the liquidity which is very difference like UAE banks.

Aim: The incidence of heart-related disease conditions due to consumption of cholesterol containing oils and the increasing global demand for oil for domestic and industrial purposes have necessitated the need for scientific evaluation of other neglected indigenous plants for potential quality oil yield. This study thus aimed at extracting and comparing physicochemical and nutritional properties of seed oils from Glycine max and Sesamum indicum with a view to diversifying alternative sources of oil to meet teeming industrial and health needs and for food security.

Methodology: Solvent extraction method was employed to extract oil from seed samples which were further subjected to estimation of physicochemical indices such as free fatty acid, saponification value, iodine value, peroxide value, specific gravity, refractive index, density, pH, melting temperature and viscosity according to methods described by using titration method.

Results: Findings indicated higher saponification (412.33 mgKOH/mg), acid (2.99 mgKOH/g), free fatty acid (1.49 mgKOH/g), viscosity (0.13 Pas) and melting point (5.66 oC) values for sesame seed oil than for soybean seed oil. However, soybean seed oil showed higher density (0.837 g/ml), specific gravity (0.842 Kg/m3), pH (6.21), iodine (47.25 wij’s or g/iodine/g) and peroxide (40.80 mEq/Kg) indices than that obtained for sesame seed oil though mean values were not significantly different.

Conclusion: From observed measured parameters, sesame seed may be suitable for industrial purposes such as the production of soap and paint owing to its high saponification, free fatty acid, viscosity and melting point values while soybean seed oil may be excellent source for domestic and nutritional consumption in addition to industrial use.

Published: June 2021

The growing human population has put enormous pressure on agriculture to increase production and productivity, which has resulted in the widespread usage of agrochemicals. The indiscriminate use of agrochemicals has harmed soil fertility and resulted in significant environmental contamination, impacting human health. The discovery and implementation of bacterial isolates with Plant Growth Promoting Rhizobacteria (PGPR) have enormous potential for reducing the usage of chemical fertilizers, insecticides, and herbicides. However, the identification of bacterial isolates is a prerequisite to utilize them for agricultural purposes. Traditional methods involve culturing microbes using a range of nonselective and selective enrichment methods, followed by biochemical confirmation among others. Traditional methods involve culturing microbes, followed by morphological biochemical confirmation etc. In the present investigation, we describe a fast and effective approach for isolating and identifying bacterial isolates, followed by phylogenetic analysis and submission to GenBank.
