3. Physicochemical and microbiological dynamics of the fermentation of the ccn51 cocoa material in three maturity stages
Resumo A dinâmica físico-química e microbiológica durante a fase de fermentação do material de cacau CCN51 foi avaliada em três fases de maturidade (fase 2: 130-152 dias após a antese DDA, fase 3: 153-174 DDA e Fase 4: 175 -196 DDA). Através da técnica da microfermentación foi monitorizado a cada 24h as variáveis físico-químicas (pH, acidez ti

5. Use of Maldi-Tof MS biosensor in microbial assessment of Brazilian kefir grains
RESUMO O objetivo deste estudo foi avaliar o uso do biossensor de Maldi-Tof MS na avaliação microbiana de grãos de kefir. Maldi-Tof MS é uma nova metodologia para o diagnóstico rápido de micro-organismos. Um total de 358 micro-organismos foram isolados, 31 foram leveduras e 327 foram bactérias (divididas em bactérias láticas e acéticas). Colônias

6. In vitro study of postbiotics from Lactobacillus plantarum RG14 on rumen fermentation and microbial population
ABSTRACT An in vitro study was carried out to identify the effects of different inclusion levels of postbiotics from Lactobacillus plantarum RG14 on rumen fermentation profiles, gas production kinetics, and microbial population in rumen fluid collected from goats. Postbiotics were added at different levels (0, 0.3, 0.6, 0.9, and 1.2%) and incubated for 72 h

7. Isolation and prospection of diazotrophic rhizobacteria associated with sugarcane under organic management
Abstract Microorganisms associated with organic management are essential in nutrient transformation and release for plant use. The present study aimed to isolate, identify and characterize plant growth promoting diazotrophic rhizobacteria associated with sugarcane under organic management. Rhizospheres of organic sugarcane varieties IAC 911099 and CTC4 were

8. Antagonistic endophytic bacteria associated with nodules of soybean (Glycine max L.) and plant growth-promoting properties
Abstract A total of 276 endophytic bacteria were isolated from the root nodules of soybean (Glycine max L.) grown in 14 sites in Henan Province, China. The inhibitory activity of these bacteria against pathogenic fungus Phytophthora sojae 01 was screened in vitro. Six strains with more than 63% inhibitory activities were further characterized through optical

9. Mangrove endophyte promotes reforestation tree (Acacia polyphylla) growth
ABSTRACT Mangroves are ecosystems located in the transition zone between land and sea that serve as a potential source of biotechnological resources. Brazil's extensive coast contains one of the largest mangrove forests in the world (encompassing an area of 25,000 km2 along all the coast). Endophytic bacteria were isolated from the following three plant spec

10. REPARAÇÃO DE α-ACETILOXI-N-CICLOEXILAMIDAS ATRAVÉS DA REAÇÃO DE PASSERINI UTILIZANDO DIMETILCARBONATO COMO SOLVENTE AMBIENTALMENTE AMIGÁVEL
A series of α-acetyloxy-N-cyclohexylamides was efficiently obtained via Passerini reaction of cyclohexyl isocyanide, acetic acid, and different aromatic and aliphatic aldehydes using refluxing dichloromethane or dimethylcarbonate (DMC). Reactions performed with DMC led to desired products in moderate to good yields, corroborating this solvent as a eco-frien

11. Assessment of Rice Associated Bacterial Ability to Enhance Rice Seed Germination and Rice Growth Promotion
ABSTRACT The application of beneficial bacteria has recently been used for sustainable agriculture. In current research, 71 bacterial isolates were obtained from rice plant and the rhizosphere soil of different paddy fields in Guilan province, Iran. After primitive investigation, 40 bacteria with typical predominant characteristics were selected. By PCR-RFLP
