For the process of treating organic waste, rotary composters are frequently employed. The amount of energy used to move the organic waste is a crucial factor to consider when designing a composting machine and selecting an appropriate motor. Using a simplified model created by regression approximation from mechanical equations, the power for the movement of organic material can be expressed as a clear and specific function of the composter size, operational parameters (direction of the sun, humidity, etc.), and organic waste qualities. The effectiveness of this model is confirmed with experimental measurements on an industrial rotating composter, yielding satisfactory results and accuracy.

Integrated membrane system is one of the current leading techniques repoprted for oil-water separation in current years. These combination of different filtration membranes offered the improved separation efficiency of the integrated membrane system during oil-water separation. Although the integrated membrane system is hilighted as the promissing method for oil-water separtion in various industries, the poor membrane wettability was reported which hampers the performance of the membrane. The poor estimation of the membrane wettability in the integrated membrane feed stream leads to the pores blockages, decline oil-water efficiecy and pooor oil/water rejection ratio. The integrated membrane feed stream is prone to membrane fouling during oil-water sepration due to poor membrane wattability. To improve the performance of the integrated membrane system this review covers the membrane wettability during oil-water separation, the techniques used to improve the membrane wettability during oil-water separtion and mathematical models developed to enhance the fundermental understanding of the membrane wettability during oil-water separation. Even though the integrated membrane feed stream has been reported to be having the limitation due to the poor membrane wettabillity, the integrated membrane system is still considered to be the better technique which separates the oil-water emulsions compared to the traditional methods.

—Extraction of shape boundaries also known as image segmentation that tries to divide a digital image into several segments for further processing is an important step in digital image analysis. The segmented images are useful in many applications such as object detection, object classification, biometric authentication, and disease diagnosis. This task can be accomplished effectively using active contour model. The two types of active contour models are global segmentation and selective segmentation. A global segmentation model is a way for segmenting an image's entire objects. Global models, unfortunately, are unable to segment a single object’s shape boundary that must be extracted. A selective segmentation model, which seeks to segment selected object’s shape boundary in an image, can overcome this restriction. The recent selective segmentation model for vector valued images has a significant computational cost due to the requirement of solving the curvature term, that result from the usage of traditional regularization term in the formulation. Hence, we proposed a new selective segmentation model for vector valued image by replacing the traditional regularization term with Gaussian function which is easier and faster to solve. The proposed model was tested using MATLAB software in segmenting synthetic, natural and medical images. Numerical experiments shows that the proposed model was about 247 times faster than the existing model with a comparable accuracy.

Evaluating the reproductive indicators in sheep breeding in Colombia, particularly males, is essential to achieve optimal production parameters. This study aimed to evaluate the semen quality of male goats through both conventional and functional seminal analysis. Semen samples from eight goats were collected and conventional (volume, appearance, colour, motility, vigour, and morphology) and functional (plasma membrane integrity, mitochondrial membrane potential, DNA integrity, lipid peroxidation, and reactive oxygen species production) seminal parameters were evaluated. The results showed an average scrotal circumference of 25.69 cm, seminal volume of 0.51 mL, and concentration of 1936 x 106 sperm/mL. The average individual motility was 63.37%, vigour was four, and the percentage of abnormalities was 7.75%. Individual motility was correlated with the mitochondrial membrane potential (r=0.840, P=0.009) and reactive oxygen species production (r=-0.91, P=0.001). The average of cells with high mitochondrial membrane potential was 52.94%, while 39.29% were necrotic cells, the DNA fragmentation index average was 12.5%, reactive oxygen species production was 38.68%, lipoperoxidation analysis was 7.33% on average, and the integrity of the membrane was 54.77%. The results establish the parameters for the semen from Antioquia goats and confirm that goat semen is of good quality and could be used during artificial insemination programs.

Three-dimensional printing, which appeared in the 1980s and has been steadily improving ever since, is a new and very promising technology. Thanks to its unique process of depositing material layer by layer, it differentiates itself from the rest of the traditional methods of modeling by molding and removing material. Modeling by adding material allows 3D printing to create parts with very complex geometries, and even with unprecedented precision. This last characteristic allows it to be used in many sectors including aviation, automotive, production but also science, education and medicine. With regard to these latter fields of application, printing by adding material is for some authors a real revolution. For modeling learning and training mockups, manufacturing custom prostheses, or printing biological and functional organs, the range of possible uses for 3D printing seems immense and very promising. In this study, we invite you to discover the main applications of the 3D printer in veterinary medicine
A New Paradigm of Literacy
Authors: Idris Akhmad
Published: September 2022

The industrial revolution is a term to label industrial development from era to era. The first phase started in the early 18th century and has now entered the fourth phase, or 4.0. Davies (2015) stated that the 1.0 industrial revolution began with the use of steam engines and machines to replace human force. In the 2.0 industrial revolution, steam engines were replaced by electrical production machines as mass production engines. The 3.0 industrial phase was characterized by the emergence of computers in the 1970s. Finally, the rapid development of interconnected technology, sensor, and data analysis became the signs of the 4.0 industrial revolution emergence. The development has impacted conventional industries in the form of digitalization. Online transportation mode is one of the most prominent impacts of the fourth industrial revolution. This phase also creates massive shifts in many sectors, such as the use of video calls, fingerprints, and face scanners as security locks, social media to connect people from all around the world, and the digitalization of books, magazines, and journals

Published: September 2022

The MEWOU river, which crosses the town of Bafoussam, is one of the main sources of drinking water and irrigation for the populations who live there. It is subject to intense agricultural and industrial activity all along its banks. Soap and refined oil factories generate pollution in the form of liquid effluents which are discharged without any form of treatment. The objective of this study is to assess the impact of soap factory effluent discharges on the quality of the surrounding water. In total, seven samples were analyzed during March, April, and May of the year 2021. The results we obtained were analyzed according to the regulatory requirements recommended by the Directives for the quality of drinking water and the Algerian standard relating to the limit values of the physico-chemical parameters. The results we obtained showed signs of significant pollution in particular: chemical oxygen demand (COD: 125.32-959 mg.L-1), 5 days-biochemical oxygen demand (BOD5: 23-99 mg.L-1 ), turbidity (2-520 NTU), TDS (130-13430 mg.L-1), Nitrite (4.96-21327.44 mg.L-1) and many other parameters greatly exceed those required by the international standard, we also noted strong pollution with heavy metals: chromium (35.76-1381.08 mg.L-1), lead (0.21 - 2.49 mg.L-1), iron (0.28- 17.82 mg.L-1), and cadmium (0.03-0.19 mg.L-1) which are above the values prescribed by the WHO. These highly polluted effluents released into the natural environment are harmful to the environment, biodiversity, and human health. This state of affairs requires urgent intervention to preserve the ecological balance. Otherwise, it can constitute a risk for public health in the short term by deteriorating the quality of the underground reservoir known as the main source of water supply for neighboring populations.
Pork Lard Derived Biodiesel Production: Characterization, Engine Performance and Emission Analysis
Authors: Robert Rohan Jeffry , Girish C. R.
Published: September 2022

The present work introduces a new methodology in the production of biodiesel from pork-lard waste having high cholesterol content and discusses its improved performance and emissions in a diesel engine. The traditional method of transesterification does not work with cholesterol due to the absence of triglycerides, therefore, the new improved method oxidizes cholesterol to fatty acids and then converts it to biodiesel ester. The procedure includes an acid reagent to break cholesterol and a renewable basic catalyst from seashells, for catalyzing the production. The acid-base system maintains the overall pH while yielding 95.6% conversion at the optimized conditions. The morphology of the produced catalyst was analyzed through FESEM and confirmed through XRD and EDX analyses. The physicochemical and ASTM properties were determined and the calorific value of the 20% biodiesel blend was found to be comparable with that of diesel. From the engine performance analysis, the thermal efficiency of the engine was observed to be higher and the exhaust emissions showed a maximum of 75% reduction in CO and 42.2% reduction in CO2 emissions, proving it to be an environment-friendly fuel. Additionally, a 32.7% reduction in smoke opacity was also observed, thus decreasing the concentration of particulate matter in the atmosphere.

Published: September 2022

Soil erosion is one of the major environmental problems facing the world. The multi-scale characteristics of soil erosion and the complexity of its influencing factors put forward higher requirements for soil erosion prevention and control. Based on GIS technology and the RUSLE model, this paper quantitatively studies the temporal and spatial variation characteristics of soil erosion intensity in Chengde City(CC) from 2003 to 2018 and analyzes the temporal and spatial characteristics of R, K, LS, C, P factors according to the model calculation results, and analyzes the formation mechanism of key units of soil erosion in CC. The results show that: The area of tolerable erosion in CC in 2018 was 35152.19 km2 (accounting for 90.22% of the total area), which was at the level of tolerable erosion on the whole. The average soil erosion modulus of CC in 2003, 2006, 2009, 2012, 2015, and 2018 were 41.38, 45.06, 46.58, 83.66, 27.67, and 73.34 t.km-2.y-1, reaching the maximum value of 83.66 t.km-2.y-1 in 2012, showing a rising trend and then declining trend in the research period. Soil erosion deteriorated in some areas of CC and regional differences increased, which caused serious environmental problems. Fitting results showed that the R factor was one of the important factors for the increase of regional differences and average erosion modulus. According to the characteristics of the problem, a precise governance model of soil erosion prevention based on the intensity and causes of soil erosion was put forward, and a “landing” scheme of soil erosion prevention and control measures was put forward. Furthermore, the control of soil and water loss in key areas should be strengthened in the future.
Migration in the Russian-Kazakhstan Border Region (on the Example of the South Urals)
Authors: Avdashkin Andrey A.
Published: September 2022

After the collapse of the USSR, the contours of the new state borders crossed the areas of settlement of ethnic groups, making the issue of the nature of the frontier actual. In the Russian-Kazakh sector, this was clearly manifested in the discrepancy between the areas of settlement of the Russian-speaking population and the very line of the state border. The challenges generated by the Kazakhization policy and the difficulties of post-socialist transit stimulated the outflow of the population from the northern regions of Kazakhstan to Russia. The purpose of the article is to reconstruct the migration of the Russian-speaking population in the Russian-Kazakh border area using the example of the South Urals. The source database was made up of archival documents, information from the regional statistics committee on migration, and materials from interviews with Russian-speaking migrants from Kazakhstan. The basis of Central Asian migration to the region was the Russian-speaking population of the border regions of Kazakhstan (Russians, Tatars, Ukrainians, Germans). Two waves of migration stand out clearly: “forced” in the 1990s., and more “pragmatic” in 2000-2019 allowed to significantly compensate for the demographic losses, contributed to the influx of a young and economically active population into the region. The main areas of their exodus were Kostanay and Rudny (Kostanay region). The developed practices of cross-border cooperation and the presence of previously established communities allowed the newcomers to maintain strong ties with their “homeland”, to facilitate the recruitment of new migrants. In the course of the study, the author identified the quantitative and qualitative parameters of migration from Kazakhstan, and determined the role of the frontier in the migration processes to the South Urals.
Faster Constant-Time Decoder for MDPC Codes and Applications to BIKE KEM
Authors: Paiva Thales B. , Terada Routo
Published: September 2022

BIKE is a code-based key encapsulation mechanism (KEM) that was recently selected as an alternate candidate by the NIST’s standardization process on post-quantum cryptography. This KEM is based on the Niederreiter scheme instantiated with QC-MDPC codes, and it uses the BGF decoder for key decapsulation. We discovered important limitations of BGF that we describe in detail, and then we propose a new decoding algorithm for QC-MDPC codes called PickyFix. Our decoder uses two auxiliary iterations that are significantly different from previous approaches and we show how they can be implemented efficiently. We analyze our decoder with respect to both its error correction capacity and its performance in practice. When compared to BGF, our constant-time implementation of PickyFix achieves speedups of 1.18, 1.29, and 1.47 for the security levels 128, 192 and 256, respectively.
Perceived Information Revisited
Authors: Ito Akira , Ueno Rei , Homma Naofumi
Published: September 2022

In this study, we present new analytical metrics for evaluating the performance of side-channel attacks (SCAs) by revisiting the perceived information (PI), which is defined using cross-entropy (CE). PI represents the amount of information utilized by a probability distribution that determines a distinguishing rule in SCA. Our analysis partially solves an important open problem in the performance evaluation of deep-learning based SCAs (DL-SCAs) that the relationship between neural network (NN) model evaluation metrics (such as accuracy, loss, and recall) and guessing entropy (GE)/success rate (SR) is unclear. We first theoretically show that the conventional CE/PI is non-calibrated and insufficient for evaluating the SCA performance, as it contains uncertainty in terms of SR. More precisely, we show that an infinite number of probability distributions with different CE/PI can achieve an identical SR. With the above analysis result, we present a modification of CE/PI, named effective CE/PI (ECE/EPI), to eliminate the above uncertainty. The ECE/EPI can be easily calculated for a given probability distribution and dataset, which would be suitable for DL-SCA. Using the ECE/EPI, we can accurately evaluate the SR hrough the validation loss in the training phase, and can measure the generalization of the NN model in terms of SR in the attack phase. We then analyze and discuss the proposed metrics regarding their relationship to SR, conditions of successful attacks for a distinguishing rule with a probability distribution, a statistic/asymptotic aspect, and the order of key ranks in SCA. Finally, we validate the proposed metrics through experimental attacks on masked AES implementations using DL-SCA.
Redshift: Manipulating Signal Propagation Delay via Continuous-Wave Lasers
Authors: Yamashita Kohei , Cyr Benjamin , Fu Kevin , Burleson Wayne , Sugawara Takeshi
Published: September 2022

We propose a new laser injection attack Redshift that manipulates signal propagation delay, allowing for precise control of oscillator frequencies and other behaviors in delay-sensitive circuits. The target circuits have a significant sensitivity to light, and a low-power continuous-wave laser, similar to a laser pointer, is sufficient for the attack. This is in contrast to previous fault injection attacks that use highpowered laser pulses to flip digital bits. This significantly reduces the cost of the attack and extends the range of possible attackers. Moreover, the attack potentially evades sensor-based countermeasures configured for conventional pulse lasers. To demonstrate Redshift, we target ring-oscillator and arbiter PUFs that are used in cryptographic applications. By precisely controlling signal propagation delays within these circuits, an attacker can control the output of a PUF to perform a state-recovery attack and reveal a secret key. We finally discuss the physical causality of the attack and potential countermeasures.

Published: September 2022

Despite the growing demand for software implementations of ECDSA secure against attackers with full control of the execution environment, scientific literature on ECDSA white-box design is scarce. The CHES 2021 WhibOx contest was thus held to assess the state-of-the-art and encourage relevant practical research, inviting developers to submit ECDSA white-box implementations and attackers to break the corresponding submissions.In this work, attackers (team TheRealIdefix) and designers (team zerokey) join to describe several attack techniques and designs used during this contest. We explain the methods used by the team TheRealIdefix, which broke the most challenges, and we show the efficiency of each of these methods against all the submitted implementations. Moreover, we describe the designs of the two winning challenges submitted by the team zerokey; these designs represent the ECDSA signature algorithm by a sequence of systems of low-degree equations, which are obfuscated with affine encodings and extra random variables and equations.The WhibOx contest has shown that securing ECDSA in the white-box model is an open and challenging problem, as no implementation survived more than two days. In this context, our designs provide a starting methodology for further research, and our attacks highlight the weak points future work should address.
Power to Pulse Width Modulation Sensor for Remote Power Analysis Attacks
Authors: Udugama Brian , Jayasinghe Darshana , Saadat Hassaan , Ignjatovic Aleksandar , Parameswaran Sri
Published: September 2022

Field-programmable gate arrays (FPGAs) deployed on commercial cloud services are increasingly gaining popularity due to the cost and compute benefits offered by them. Recent studies have discovered security threats than can be launched remotely on FPGAs that share the logic fabric between trusted and untrusted parties, posing a danger to designs deployed on cloud FPGAs. With remote power analysis (RPA) attacks, an attacker aims to deduce secret information present on a remote FPGA by deploying an on-chip sensor on the FPGA logic fabric. Information captured with the on-chip sensor is transferred off the chip for analysis and existing on-chip sensors demand a significant amount of bandwidth for this task as a result of their wider output bit width. However, attackers are often left with the only option of using a covert communication channel and the bandwidth of such channels is generally limited. This paper proposes a novel area-efficient on-chip power sensor named PPWM that integrates a logic design outputting a pulse whose width is modulated by the power consumption of the FPGA. This pulse is used to clear a flip-flop selectively and asynchronously, and the single-bit output of the flip-flop is used to perform an RPA attack. This paper demonstrates the possibility of successfully recovering a 128-bit Advanced Encryption Standard (AES) key within 16,000 power traces while consuming just 25% of the bandwidth when compared to the state of the art. Moreover, this paper assesses the threat posed by the proposed PPWM to remote FPGAs including those that are deployed on cloud services.
Side-Channel Expectation-Maximization Attacks
Authors: Béguinot Julien , Cheng Wei , Guilley Sylvain , Rioul Olivier
Published: September 2022

Block ciphers are protected against side-channel attacks by masking. On one hand, when the leakage model is unknown, second-order correlation attacks are typically used. On the other hand, when the leakage model can be profiled, template attacks are prescribed. But what if the profiled model does not exactly match that of the attacked device?One solution consists in regressing on-the-fly the scaling parameters from the model. In this paper, we leverage an Expectation-Maximization (EM) algorithm to implement such an attack. The resulting unprofiled EM attack, termed U-EM, is shown to be both efficient (in terms of number of traces) and effective (computationally speaking). Based on synthetic and real traces, we introduce variants of our U-EM attack to optimize its performance, depending on trade-offs between model complexity and epistemic noise. We show that the approach is flexible, in that it can easily be adapted to refinements such as different points of interest and number of parameters in the leakage model.
On the application of Two-Photon Absorption for Laser Fault Injection attacks

Published: September 2022

Laser Fault Injection (LFI) is considered to be the most powerful semiinvasive fault injection method for implementation attacks on security devices. In this work we discuss for the first time the application of the nonlinear Two-Photon Absorption (TPA) effect for the purpose of LFI. Though TPA is an established technique in other areas, e.g. fluorescence microscopy, so far it did not receive any attention in the field of physical attack methods on integrated circuits. We show that TPA has several superior properties over the regular linear LFI method. The TPA effect allows to work on non-thinned devices without increasing the induced energy and hence the stress on the device. In contrast to regular LFI, the nonlinearity of the TPA effect leads to increased precision due to the steeper descent in intensity and also a vertically restricted photoelectric effect. By practical experiments, we demonstrate the general applicability of the method for a specific device and that unlike a regular LFI setup, TPA-LFI is capable to inject faults without triggering a latch-up effect. In addition we discuss the possible implications of TPA-LFI on various sensor-based countermeasures.

Objective: Nanofat grafting has been reported to improve tissue repair by the Stromal Vascular Fraction (SVF) of nanofat. However, the oil and liquid portions of fat tissues were released by mechanical emulsification during the nanofat procedure. Here, we reported a simple method to remove the oil and water for concentrating nanofat.

Methods: The concentrate of nanofat was obtained by processing nanofat using negative pressure produced by syringer and two-step centrifugation. The volume of oil and fat tissue as well as morphological changes of nanofat concetrate obtained by different procedures was examined. Meanwhile, the SVF numbers, the proliferation and differentiation capacity of Adipose-Derived Stem Cells (ADSCs) were determined. The clinical outcome of nanofat concentrate in treatment hypertrophic scar was evaluated.

Results: The centrifugation and negative pressure had no significant effect on the proliferation activity of the SVF in the concentrate of nanofat. The concentrated rate after 0, 15, 30 and 60 times of emulsification was 2.08±0.042, 2.63 ± 0.07, 3.8 ± 0.01 and 8.2 ± 0.12 times greater than the original, respectively. The SVF number per 10 ml of fat in the above-mentioned groups were increased by 1.80 ± 0.15, 2.68 ± 0.27, 4.64 ± 0.20 and 3.44 ± 0.27 times, respectively. The capacity of cell proliferation and differentiation decreased significantly after more than 30 times emulsification. The concentrates of nanofat effectively improve the appearence and hardness of hypertrophic scar.

Conclusion: The nanofat concentrate prepared by our method include more SVF cells and less oil and might be more effective during clinical use.

Biosurfactant-expressing bacteria have been shown to have potential in many biotechnological applications including the biodegradation of petroleum fractions, such as premium motor spirit (PMS). This study was aimed at investigating the potential use of biosurfactant-expressing bacterial isolates in the biodegradation of premium motor spirit (PMS) at various concentrations (100-100,000ppm). The biosurfactant-expressing bacteria were isolated from mechanic workshop in Malumfashi, Katsina, Nigeria using standard techniques. The isolates identified belonged to the genera Acinetobacter, Bacillus, Micrococcus, Pseudomonas and Stenotrophomonas. These isolates were screened for biosurfactant expression using drop collapse, haemolysis, oil–water behavior assays and emulsification index test. Positives isolates were investigated for PMS degradation by growing the isolates on mineral salt media supplemented with (0.1ml) premium motor spirit (PMS) as sole source of carbon. Although, higher total hydrocarbon degrading bacterial counts were obtained from soils where isolates positive for biosurfactant expression are predominant, there was no statistically significant difference between isolate source using Kruskal-Wallis H test (p = 0.67). The isolates Bacillus velezensis and Stenotrophomonas maltophilia were positive for biosurfactant-production potential using drop-collapse, β-haemolysis, oil spreading, and emulsification index and drop collapse tests with higher tolerance to PMS at concentrations up to 100,000 ppm. Statistical analysis using multiple-comparison analysis of variance (ANOVA) confirmed that the isolates exhibited varying PMS degradation response (p = 0.0066); furthermore, the tolerance of the bacteria to the PMS is dose-dependent (p = 0.00012). Post-hoc analysis using Tukey’s test identified Bacillus velezensis as the most efficient biosurfactant-producing and hydrocarbon degrading isolate (p = 0.0264 and 0.0034); moreover, the threshold concentration for high PMS tolerance was found to be 1000ppm and above (p = 0.0174, 0.0008 and 0.0001).These isolates’ ability to grow on mineral salt media supplemented with PMS as a sole source of carbon presents a veritable avenue for exploitation in biotechnology, towards biosurfactants-mediated bioremediation of hydrocarbon pollutants in oil contaminated soils.

Methicillin-resistant Staphylococcus aureus (MRSA) is a major public health concern, and it is responsible for both hospital and community associated infections globally. In this study, we aimed at determining the prevalence and pattern of resistance of MRSA to commonly used antibiotics in Anyigba, Nigeria. This was a hospital based, cross-sectional study conducted between August 2017 and February 2018. One hundred and fifty routine clinical specimens were collected from selected health facilities in Anyigba for laboratory analyses. Standard laboratory methods were employed in the identification of the isolates. Methicillin-resistant Staphylococcus aureus (MRSA) was confirmed using Oxacillin Resistance Screening Agar Base (ORSAB) supplemented with 2g/l of Oxacillin. Screening to determine the antibiotic resistance profiles of all confirmed MRSA isolates was by disc diffusion method. A total of 124 (82.7%) isolates of Staphylococcus aureus were recovered from clinical samples obtained. Of these isolates, 28 (22.6%) were methicillin resistant. The percentage distribution rate of MRSA was highest (50.0%) in urine samples. Majority of these isolates were resistant to at least four of the six antibiotics tested. Most of the isolates recovered from urine samples were resistant to Gentamicin (92.9%), Amoxicillin (100.0%) and Cotrimoxazole (85.7%). Our study showed a significant presence of MRSA isolates in the clinical specimens collected, with a relatively high rate to gentamicin, Amoxicillin and Cotrimoxazole antibiotics. This study highlights the need for monitoring of antimicrobial use considering the lack of innovation in the development of new antimicrobials which lessens efforts at combating infections caused by antibiotic-resistant pathogens.

Exopolysaccharides (EPS) are exogenous bacterial sugar polymers with many applications in dairy, pharmaceutical and cosmetic industries, using it as thickeners, stabilizers and gelling agents. The study aimed to screen for potential exopolysaccharide producers from Lactobacillus spp. isolated from locally fermented milk (nono). Twenty-five nono Samples were collected from Wambai market, Kano. Lactic acid bacteria were isolated using de Man Ragosa and Sharpe Agar. Isolates were identified by API 50 CHL kit and web, and screened for EPS production in which the EPS was extracted and quantified using the phenol-sulphuric method. Next, the influence of carbon source (Glucose, Sucrose and Lactose) and concentrations on EPS were evaluated on some of the isolated strains. The functional groups of the EPS were confirmed using FTIR. The isolated Lactobacillus spp. were all Gram positive, catalase and oxidase negative, API identification yielded; Lactobacillus acidophilus 1, Lb. brevis 1, Lb. fermentum, Lb. paracasei ssp paracasei, Lb. acidophilus 3. Ten isolates yielded EPS in the range of 248.33mg/l - 07.83mg/l. The FTIR analysis of extracted EPS produced peaks around 3,300–881cm-1. Hence the study has brought to light the presence of potential EPS producing LAB in nono, which could be further exploited to harness their potential.
