Investigating the effect of clicker use on problem-solving among adult learners: A cross-sectional survey
Authors: Bin Mubayrik Haifa Fahad
Published: May 2020

Classroom response systems (clickers) have been found to engage and attract student attention and facilitate the practical application of key ideas to solve problems. This study was designed to investigate the effects of clicker use on problem-solving among adult learners. A self-administered questionnaire was distributed to 60 students after giving them actual case studies for problem-solving using PowerPoint slides. An equal number of participants were assigned to each of the control (n=30) and experimental groups (n=30). Although both groups engaged in the same problem-solving tasks, the experimental group used clickers as a learning tool in the classroom. Data were analyzed using frequency, means, exploratory factor analysis, the Friedman ranking test, and linear regression analysis. The study findings revealed overall positive responses toward using clickers in the classroom. They also suggested that clickers encouraged thinking and problem-solving. It is concluded that problem-solving learning in adult education appears to be more effective when accompanied by clicker use than through conventional teaching methods.Received: 26 September 2019Accepted: 04 March 2020Published online: 19 May 2020

This work presents the advances being made on a research project addressing curriculum processes for the development of competencies at the San Juan National University’s Faculty of Engineering (Argentina) in the framework of institutional policies that seek to make its programs of study appropriate for the second generation of accreditation standards. This is an exploratory, descriptive and interpretative study that is currently in the analytic phase, during which time we have carried out a characterization of the study plans currently in force for seven engineering programs in place at the university. In this sense, we describe both the institutional transformation related to the creation of accreditation standards and the perspectives of institutional actors as regards the curriculum design of the San Juan National University Faculty of Engineering’s programs, analyzing the institutional dynamic that emerges from said process.Received: 27 December 2019Accepted: 04 March 2020Published online: 19 May 2020
Stakeholder perspectives on general competences: The case of graduates of Vietnam National University, Hanoi
Authors: Mai Lan Thi Quynh
Published: May 2020

This research draws from theories of graduate employability and transferable skills and the TASE project’s 13 graduate competences model, to explore the evaluation of the various stakeholders concerning the degree to which VNU graduates have acquired general competences. The survey measured three variables: (i) importance, (ii) achievement and (iii) priority, using the four categories of ‘none’, ‘weak’, ‘considerable’, and ‘strong’. Between February and December 2018, a total of 818 informants agreed to participate, including 168 employers, 152 alumni, 189 students who had just graduated in 2018 or were about to graduate, 51 lecturers and university managers, and 258 students. The importance of the 13 general competences was rated more highly than graduate achievement. The ability to uphold professional, moral and ethical values was rated by VNU employers as of greatest importance and the highest achievement. Similarly, VNU students and alumni rated this ability as their highest achievement. The ability to conduct research and the ability to understand, value, and respect diversity and multiculturalism were rated as of lowest importance by VNU employers. The former (ability to conduct research) was rated as of lowest importance by VNU alumni and their lowest achievement by both VNU alumni and VNU students. VNU students rated the latter ability (to understand, value, and respect diversity and multiculturalism) as of least importance. The ability to initiate, plan, organise, implement and evaluate courses of action was rated the lowest achievement by VNU employers. The ability to apply knowledge in practice was considered of greatest importance by both VNU students and alumni, but for the latter group this ability ranked equally with the ability to communicate clearly and effectively. Students gave most of their own general competences a significantly lower rating than that given by employers to alumni achievement.Received: 26 June 2019Accepted: 13 March 2020Published online: 19 May 2020

Published: May 2020

Se ha establecido un Grupo de Estudio y análisis sobre la mortalidad materna en Bogotá, liderado por personas desde el sector privado que han ofrecido su colaboración al sector público para que se emprendan acciones encaminadas a reducir la incidencia de este fenómeno. El éxito, luego de dos reuniones celebradas en julio y en agosto de 1993, es relativo: no se ha logrado aún capitalizar el interés entre las autoridades del sector público que esta clase de esfuerzos supone. El entusiasmo de los impulsadores no obstante, se mantiene muy en alto y la decisión ha sido, continuar adelante hasta lograr que algún día se reconozca que una ciudad como la capital colombiana debe y puede alcanzar niveles de salud materna similares a las de cualquier capital del mundo industrial porque posee desde hace mucho tiempo los elementos suficientes para lograrlo
Tamizaje prenatal de enfermedades fetales genéticas y adquiridas midiendo tres marcadores en suero materno: determinación de AFP, BHcG y E3 no conjugados
Authors: Acuña J. M.
Published: May 2020

La determinación de fetos anormales se ha basado tradicionalmente en la selección de pacientes por edad materna o antecedentes personales y familiares, detectando sólo un pequeño número de fetos anormales. La introducción de la medición y estandarización de tres marcadores en suero materno (Aifafetoproteína, AFP, gonadotropina coriónica, BHcG, y estrioles no conjugados, uE3) ha probado ser una herramienta útil en la selección de un grupo importante (54% a 67%) de pacientes que sin tener otra indicación para diagnóstico prenatal, gestan fetos anormales y/o tienen gestaciones anormales. La dificultad de la aplicación del triple marcador estriba en: 1. la necesidad de tener curvas estandarizadas para su interpretación, 2. la interpretación cuantitativa de los valores absolutos de la prueba basados en programas de computador complejos y costosos y 3.Ia interpretación clínica de los resultados basada en un análisis de regresión gaussiano de triple variable, haciendo que los valores obtenidos sean de utilidad al clínico.La presente revisión proporciona las líneas de manejo, indicaciones y protocolos actuales de aplicación del tamizaje con Triple Marcador.

Published: May 2020

Aunque el Test de no estrés, es un método ampliamente aceptado de vigilancia fetal, uno de sus problemas ha sido la falta de estándares para su interpretación. Se valoraron prospectivamente 142 pruebas, realizadas en 90 pacientes, utilizando un sistema de calificación de parámetros múltiples que cuantifica cinco variables: frecuencia cardíaca basal, frecuencia y amplitud de las oscilaciones, aceleraciones y desaceleraciones. Empleando estrictos parámetros de confirmación del Bienestar Fetal, el sistema tuvo una sensibilidad del 50%, especificidad del 98.4% y exactitud del 96.9%. El análisis de las mismas pruebas utilizando solamente criterios de reactividad dio una sensibilidad del 75%, especificidad del 92% y exactitud del 91.6%.La cuantificación de parámetros múltiples del TNS permiten una lectura fácil y objetiva de los trazados, independiente de la presencia de movimientos fetales. Facilita el análisis de trazados de dudosa reactividad y unifica criterios de interpretación para comparar estudios entre grupos e instituciones.

Este trabajo tiene como objetivo comprobar la aplicación de la US endovaginal (USE) en obstetricia, sus beneficios e inconvenientes en relación con la técnica abdominal, la utilidad diagnóstica en alteraciones embrionarias, fetal es, ovulares y maternas durante el embarazo, además de un análisis del futuro de la (USE) en el plano investigativo.Para este estudio se seleccionaron pacientes entre abril de 1990 y octubre de 1991 de la Unidad de Alto Riesgo Obstétrico del Departamento de Ginecología y Obstetricia del Hospital Simón Bolívar que necesitasen un estudio ecográfico integral (US Abdominal y Endovaginal), según los parámetros antes mencionados, y se citaron a un programa secuencial de estudio ecográfico correlacionado con los hallazgos clínicos y paraclínicos de cada caso. Siendo este programa uno de los resultados de la política académica de nuestro postgrado de gineco-obstetricia consistente en vincular al servicio tecnología foránea mediante la colaboración de instituciones privadas.En dicho estudio se utilizó un ultrasonógrafo PHILIPS de 256 grises de resolución con un transductor lineal de 4 MHZ, un sectorial de foco medio de 3.5 MHZ, y un endovaginal de 7.5 MHZ con un ángulo de visión de 90°. Las gráficas se imprimieron en un printer de papel termosensible de alta resolución. Se efectuó además como soporte teórico una revisión bibliográfica de más de 100 referencias entre 1987-1991 sobre temas como: los usos de la USE en el primer trimestre normal y patológico, su correlación con los niveles séricos de BHCG, el papel de la USE en el diagnóstico precoz de anomalías congénitas, su uso en la incompetencia cervical y placenta previa.Todo esto compendiado en 8 capítulos e ilustrado con un reporte gráfico de 60 ilustraciones sobre nuestra experiencia en cada uno de estos temas.Después de un año de estudios ecográficos correlacionados (clínico-imagenológico), no dudamos en concluir que la US Endovaginal marca una nueva era en el diagnóstico precoz en obstetricia y por ende en la terapéutica de la obstetricia moderna.
Valor semiológico de la secreción mucosa genital de la recién nacida

Estrategias de Ahorro Energético en Hogares: ¿Termotanque Eléctrico o Gas?
Authors: Juanicó Luis E. , Bove Italo
Published: May 2020

Se presentan novedosas estrategias de ahorro energético utilizando termotanques eléctricos hogareños con las que obtenienen ahorros significativos, desde 675 kWh/año para un único usuario hasta 2.490 kWh/año para una familia de siete miembros, que se traducen (tarifa 3 $/kWh) en $2.000 y $7.500 al año. Instalando tres termotanques: uno compacto 20 litros en cocina a 50 °C, otro de 50 litros a 45 °C en un baño, ambos con reloj programador y desconección nocturna, y otro de 150 litros en otro baño (apagado y con encendido remoto) el consumo anual de esta familia se reduce a $14.000 contra $21.500 de la configuración básica (un termotanque 150 litros siempre a 75 °C). Se discute la conveniencia del uso de termotanques eléctricos o gas (natural o envasado). El costo anual de combustible con gas natural (4 $/m3) o envasado (50 $/kg) para esta familia asciende a $4.400 y $55.000, respectivamente; no obstante incluyendo otros costos asociados (mantenimiento y seguridad, $12.500 anuales) la comparación favorece a la mejor opción eléctrica. Esta conclusión podría cambiar el paradigma a favor del gas natural en hogares, y concientizaría sobre sus riesgos.

Published: May 2020

Aim: To evaluate the influence of social capital on self-perception related to orthodontic treatment need. Methods: A cross-sectional study was conducted with a sample of 578 11-16 years-old adolescents from a city in southern Brazil. Social capital was evaluated using the Social Capital Questionnaire for Adolescent Students (SCQ-AS). Index of Orthodontic Treatment Need (IOTN) assessed malocclusion and self-perception related to orthodontic treatment need. Sociodemographic aspects of adolescents were also evaluated. Individual analyses were performed, relating the study variables to the outcome, estimating the odds ratio with the respective confidence intervals of 95%. The variables with p<0.20 in the individual analyses were tested in the multiple logistic regression models, and those with p<0.10 remained in the model. Results: Social capital did not influence the self-perception related to orthodontic treatment need. Adolescents with high orthodontic needs were 5.35 (CI 95%: 2.68 to 10.65) times more likely to perceived orthodontic treatment need (p <0.05). Crowding and dental absence were associated with self-perception related to orthodontic treatment need (p <0.05). Conclusions: Social capital did not influence the self-perception related to orthodontic treatment need.

In this study, a wavelet denoising method is first used to eliminate the influence of noise. Then, an overlapping smooth window technique is introduced into the asymmetric multifractal detrended cross-correlation analysis method, which was combined with the multiscale multifractal analysis method, resulting in the proposed asymmetric multiscale multifractal detrended cross-correlation analysis method. This method not only remedies the pseudo-fluctuation defect of the traditional method, but also explores the asymmetric multifractal cross-correlation between China’s rebar futures and spot markets at different scales. The results show the existence of an asymmetric multifractal cross-correlation between rebar futures and spot markets with upward and downward trends at different scales. This cross-correlation is highly complex at the small-scale, and more pronounced when the futures market is in an uptrend.

This paper estimates users’ search intents when using the context search engine (CSE) by analyzing submitted queries. Recently, due to the increase in the amount of information on the Web and the diversification of information needs, the gap between user’s information needs and a basic search function provided by existing web search engines becomes larger. As a solution to this problem, the CSE that limits its tasks to answer questions about temporal trends has been proposed. It provides three primitive search functions, which users can use in accordance with their purposes. Furthermore, if the system can estimate users’ search intents, it can provide more user-friendly services that contribute the improvement of search efficiency. Aiming at estimating users’ search intents only from submitted queries, this paper analyzes the characteristics of queries in terms of typical search intents when using CSE, and defines classification rules. To show the potential use of the estimated search intents, this paper introduces a learning to rank into CSE. Experimental results show that MAP (mean average precision) is improved by learning rank models separately for different search intents.

A selective encryption algorithm is proposed to improve the efficiency of high efficiency video coding (HEVC) video encryption and ensure the security of HEVC videos. The algorithm adopts the integer dynamic coupling tent mapping optimization model as the pseudo-random sequence generator, and multi-core parallelization is used as the sequence generation mechanism. The binstrings during the process of context adaptive binary arithmetic coding are selected for encryption, which conforms to the features of invariable binstream and compatible format in terms of video encryption. Performance tests for six types of standard videos with different resolutions were performed. The results indicated that the encryption algorithm has a large key space and benefits from a high encryption effect.

With the growth of robot technology, more educational-support robots, which support learning, are paid attention to. For example, one robot supports the school life of students. Another robot helps students to learn English better. Most researches have focused on robot behavior and investigating the effect. Previous research has reported that a society in which robots and humans learn together will soon be a reality. If a society where robots and humans learn side by side is realized, children will be in houses where they will learn alongside multiple unspecified robots. We think that perspectives of third parties, such as educators and guardians, are important for further improvements in the field. Thus, we think that a system is necessary wherein third parties can direct robots to provide suitable learning support to learners. This paper proposes a system for teachers that can direct robots to provide suitable learning support to learners, who simultaneously can grasp their learning conditions as they study alongside robots.

Inherent thermal adaptation in livestock is an important economic trait that cannot be overlooked, most especially in animals reared in sub-optimal thermally stressful environments. The present study explored the possibility of using multifactorial discriminant analysis (DA) to separate two duck genera {Muscovy and Common (Mallard) ducks) and their hybrid (Mule ducks) to distinct genetic groups using physiological, haematological and biochemical parameters. Data were collected after exposure of ducks to solar radiation for 90 minutes (12.00 – 13.30 hours). The result of analysis of variance indicated that genotype significantly (P<0.05) affected heamoglobin (Hb), basophil (Bas), total protein (TP), albumin (Alb), globulin (Glb), skin temperature (SKT), respiratory rate (RRT), panting rate (PTR) and rectal temperature (RTC). Stepwise DA revealed that PTR, RRT, Bas and TP in descending order were the most important parameters discriminating the three duck genotypes. The result of cross validation showed that 71.00%, 97.30% and 50.00% of Muscovy, Common and Mule ducks were correctly classified in their expected genetic group respectively. The Euclidean distance between the duck genotypes indicated that longest distance (86.507) was between Muscovy and Common (Mallard) ducks while shortest distance (12.415) was between Muscovy and Mule ducks. The results are applicable in breed adaptation studies, management, conservation and improvement programmes.
Small Intestine Characteristics and Nutrient Retention in Broiler Chickens Submitted to Different Protein Regimes and Betaine Supplementation
Authors: Ratriyanto Adi , Sunarto Sunarto
Published: May 2020

This study was designed to determine the intestinal characteristics and nutrient retention of broiler chickens subjected to different protein regimes supplemented with betaine. Four experimental diets were formulated, consisting of two basal diets containing 20% and 23% crude protein (CP), both with and without betaine supplementation at the level of 0.14%. The diets were applied to 180 broiler chickens that were randomly allotted to 2×2 factorial arrangement with five replicates of nine chickens each. The diet with 20.0% CP generated better small intestine characteristics than the diet with 23.0% CP as indicated by the longer ileum and total small intestine length (P<0.05). This improvement was associated with lessened CP excretion and improved dry matter (DM) and CP retention (P<0.05) in the birds fed 20% CP. Furthermore, dietary betaine supplementation enhanced the ileum, total small intestine length, villus height, and villus-to-crypt ratio (P<0.05), indicating a greater surface area for nutrient absorption. This enhancement was reflected in the reduction of DM and CP excretion and improvement in DM and CP retention in the betaine supplemented group (P<0.05). Therefore, we conclude that feeding a diet of 20% CP with betaine supplementation improved the small intestine characteristics and nutrient retention of broiler chickens.

We report 2 cases of missing condylar region associated with severe elbow trauma treated with our new surgical technique and present the outcomes at the 9- and 10-year follow-ups. Our method focused on anatomical isometric point reconstruction, which consisted of the reconstruction of the missing condylar region with the iliac bone and the collateral ligament with the palmaris longus tendon.

Conclusions:

This injury is rare, and treatment is challenging because of the difficulty in identifying the isometric point. Both patients achieved good elbow function. The bone defect region was almost remodeled with minimal bone tunnel enlargement. Overall, our technique can provide positive results.
A Majority of Single Versus Double-Row Rotator Cuff Repair Comparisons Fail to Consider Modern Single-Row Techniques
Authors: Maassen Nicholas H. , Somerson Jeremy S.
Published: May 2020

Background:

There is considerable published research comparing single-row (SR) and double-row (DR) rotator cuff repairs. Conclusions of primary studies as well as multiple meta-analyses have differed. One underexplored factor has been the variability in techniques that are identified as “single-row” or “double-row.” Our goal was to conduct a systematic review of primary research and meta-analyses comparing SR and DR fixation techniques, with attention to the specific technique types compared.

Methods:

We evaluated meta-analyses and individual studies that directly compared SR and DR repairs. Primary studies from 8 high-quality meta-analyses published prior to 2014, and any Level-III or higher studies published from 2014 to 2019, were included. Specific techniques of repair were identified, and the manuscripts were classified on the basis of the specific type of simple or complex SR or DR repair that was performed. Conclusions of the studies were then assessed according to these classifications.

Results:

Twenty-two studies met the eligibility criteria; 9 were Level-I studies, 7 were Level-II, and 6 were Level-III. Of the 22 studies, only 3 (14%) of the studies compared a biomechanically superior complex SR technique and a DR repair. The remaining 19 (86%) of the studies utilized biomechanically inferior, simple SR techniques in their comparisons.

Conclusions:

While there is a large amount of published evidence comparing SR and DR rotator cuff repair techniques, there are few studies assessing how the strongest SR techniques compare with DR techniques. This identifies a deficiency in the current understanding of rotator cuff repair techniques. Future studies specifically designed with these techniques in mind will help to further the understanding of which technique is clinically and financially superior in this continuously changing medical environment.

The use of quality and certified seeds is an absolute requirement in the construction of the seed garden of coconut plant. Lobu tall coconut is one of the potential coconuts owned by North Sulawesi Province. The research was conducted  in Lobu Village, Touluwaan District, Southeast Minahasa Regency, North Sulawesi Province from 2016 to 2018. The purpose of the study was to determine the characters that directly have an impact on the yield using path analysis based on Singh and Chaudary Formula on twelve morphology characters using programme of R i386 3.5.2 package Agricole software. The results of a simple correlation analysis show that there is no relationship between morphological characters and number of fruits, but correlates with the weight of whole fruit. The results of the path analysis showed that only the seed weight character had a direct effect on the weight of whole fruit (r = 0.53) and there were no indirect effects. Seed weight characters can be used as a selection criteria of mother palms to increase coconut productivity of Odeska Lobu coconut.

Hasil analisis korelasi sederhana menunjukkan tidak terdapat hubungan antara karakter morfologi dengan karakter hasil jumlah buah, tapi berkorelasi dengan karakter hasil berat buah utuh. Hasil analisis lintas menunjukkan hanya karakter berat biji yang berpengaruh langsung terhadap berat buah utuh (r = 0.53) dan tidak terdapat pengaruh tidak langsung. Karakter berat biji dapat dimanfaatkan sebagai kriteria seleksi pohon tetua sebagai sumber benih untuk meningkatkan produktivitas kelapa Dalam Odeska Lobu. 
Morphological changes in the proximity of the Greek colonies founded along the western (Romanian) Black Sea coast: Orgame, Histria, Tomis, and Kallatis
Authors: PREOTEASA Luminita
Published: May 2020

This paper is a review of the up to date knowledge about the coastal environmental transformations around the Greek settlements along the present–day Romanian shoreline. The aim is to define a general pattern of the morphological configuration the Greeks were looking for when establishing their colonies. Existing quantitative and qualitative database on shoreline evolution both along the low lying deltaic sector (N) and along the soft rock cliffs along the southern sector of the present–day Romanian coast together with the present day morphological configuration analysis at each study site were used to assess large spatial (~180 km alongshore) and temporal scales (ca. 2500 yrs) of coastal behavior. The coastal dynamics during the late Holocene was controlled by the deltaic lobes development along the northern part of the present day Romanian coast which led to important shoreline progradation and subsequent isolation from the shoreline of Histria and Orgame Greek cities. The continuous sediment input depletion, sea level rise, storms set-up, longshore transport system and local tectonic activity drove the cliff line retreat along the southern sector, with important parts of the Tomis and Kallatis settlements being lost to the sea.
Sistema de salud de Haití
Authors: Fene Fato , Gómez-Dantés Octavio , Lachaud James
Published: May 2020

El sistema de salud haitiano se conforma por un sector público y un sector privado. El primero está compuesto por el Ministerio de Salud Pública y Población (MSPP) y la Caja de Seguro de Accidentes de Trabajo, Enfermedades y Maternidad (Ofatma). El sector privado incluye a los seguros y prestadores de servicios de salud privados. El MSPP ofrece servicios básicos a la población no asalariada (95% de la población total), mientras que la Ofatma ofrece seguros contra accidentes de trabajo, enfermedades y maternidad a los trabajadores del sector formal privado y público. El gasto total en salud en Haití representó 5.4% del producto interno bruto en 2016 y el gasto en salud per cápita fue de 38 dólares estadunidenses. Hay una enorme dependencia de los recursos externos. El MSPP es el responsable de la mayor parte de las actividades de rectoría. El mayor reto que enfrenta el sistema de salud de Haití es ofrecer servicios integrales de salud con protección financiera a toda la población. Esta meta no podrá alcanzarse sin mayores recursos financieros, sobre todo públicos, y sin un importante esfuerzo de fortalecimiento institucional.

What are the barriers, facilitators and interventions targeting help-seeking behaviours for common mental health problems in adolescents? A systematic review
Authors: Aguirre Antonia , Silva Ignacio , Billings Jo , Jimenez Magdalena , Rowe Sarah
Published: May 2020

Background: Increasing rates of mental health problems among adolescents are of concern. Teens who are most in need of mental health attention are reluctant to seek help. A better understanding of the help-seeking in this population is needed to overcome this gap. Methods: Five databases were searched to identify the principal barriers, facilitators and interventions targeting help-seeking for common mental health problems in adolescents aged 10-19 years. The search was performed in June 2018 and updated in March 2019. Two independent screening processes were made using the eligibility criteria. Quality assessment of each study was performed and findings summarised using a narrative synthesis. Results: 90 studies meet the inclusion criteria for this review for barrier and facilitators (n=54) and interventions (n=36). Stigma and negative beliefs towards mental health services and professionals were the most cited barriers. Facilitators included previous positive experience with health services and mental health literacy. Most interventions were based on psychoeducation, which focused on general mental health knowledge, suicide and self-harm, stigma and depression. Other types of interventions included the use of multimedia and online tools, peer training and outreach initiatives. Overall, the quality of studies was low to medium and there was no general agreement regarding help-seeking definition and measurements. Conclusion: Most of interventions took place in an educational setting however, it is important to consider adolescents outside the educational system. Encouraging help-seeking should come with the increased availability of mental health support for all adolescents in need, but this is still a major challenge for Child and Adolescent Mental Health Services. There is also a need to develop shared definitions, theoretical frameworks and higher methodological standards in research regarding help-seeking behaviours in adolescents. This will allow more consistency and generalisability of findings, improving the development of help-seeking interventions and ensuring timely access to mental health treatments.

Background:There is an urgent need to discover biological biocontrol agents to control bacterial wilt. This study reports on a new lipopeptide-producing biocontrol strain FJAT-46737 and explores its lipopeptidic compounds, and this study investigates the antagonistic effects of these compounds.Results:Based on a whole genome sequence analysis,the new strain FJAT-46737 was identified asBacillusvelezensis, and seven gene clusters responsible for the synthesis of bioactive secondary metabolites in FJAT-46737 were predicted. The antimicrobial results demonstrated that FJAT-46737 exhibited broad-spectrum antimicrobial activitiesin vitroagainst three bacteria and three fungi. Pot experiments showed that the control efficiencies for tomato bacterial wilt of the whole cultures, the 2-fold diluted supernatants and the crude lipopeptide of FJAT-46737 were 66.2%, 82.0%, and 96.2%, respectively. The above results suggested that one of the antagonistic mechanisms of FJAT-46737 was the secretion of lipopeptides consisting of iturins, fengycins and surfactins. The crude lipopeptides had significant antagonistic activities against several pathogens (includingRalstonia solanacearum,Escherichia coliandFusarium oxysporum) and fengycins were the major antibacterial components of the lipopeptides againstR. solanacearum in vitro. Furthermore, the rich organic nitrogen sources (especially yeast extracts) in the media promoted the production of fengycin and surfactin by FJAT-46737. The secretion of these two lipopeptides was related to temperature fluctuations, with the fengycin content decreasing by 96.6% and the surfactins content increasing by 59.9% from 20oC to 40oC. The optimal temperature for lipopeptide production by FJAT-46737 varied between 20oCand 25oC.Conclusions:TheB.velezensisstrain FJAT-46737 and its secreted lipopeptides could be used as new sources of potential biocontrol agents against several plant pathogens, and especially the bacterial wilt pathogenR. solanacearum.
