1. Conservation system improves soil microbial quality and increases soybean yield in the Northeastern Cerrado
ABSTRACT The conservation tillage systems is based on the surface protection by crop residue and reduced soil disturbance. These two principles can favor the soil quality and promote sustainable agricultural systems. The study was developed with the objective of measure soil microbial biomass, soil basal respiration, enzymatic activity and soybean yield in c

2. Effects of different legume green manures on tropical soil microbiology after corn harvest
ABSTRACT Legume green manure is a popular practice for sustainable agriculture in tropical environments. The use of grain, forage and purely green manure legumes in a subhumid tropical area in Northeast Brazil was investigated to determine the total C and N contents and estimate C-microbial biomass, soil basal respiration, microbial and metabolic quotients,

3. NATIVE MICROBIOTA AND ARBUSCULAR MYCORRHIZAL FUNGI ON GROWTH OF Paspalum millegrana SCHRAD
RESUMO Paspalum millegrana é uma poácea nativa das Américas, cuja interação com fungos simbiontes nativos ainda não pode ser encontrada na literatura. O objetivo deste trabalho foi avaliar a interação entre microrganismos nativos e fungos micorrízicos arbusculares no crescimento de P. millegrana Schrad. O delineamento experimental utilizado foi inte

5. Temporal variation of bacterial population and response to physical and chemical parameters along a petrochemical industry wastewater treatment plant
Abstract: The petrochemical industry has played a considerable role in generation and release of waste in the environment. Activated sludge and facultative lagoons are commonly used for domestic and industrial wastewater treatment due to their low-cost and minimal need for operational requirements. Microorganisms present in wastewater treatment plant (WWTP)

6. Microscale direct transesterification of microbial biomass with ethanol for screening of microorganisms by its fatty acid content
Abstract We present an improved method of direct transesterification suitable for the quantitative analysis of multiple dry samples for its fatty acid content, using a minimal amount of biomass and reactants. The method features an acid-catalyzed direct alcoholysis of microgram samples of dry biomass; the rationale behind the solvent and reagent proportions

7. Desenvolvimento de biomaterial composto por hidroxiapatita e clorexidina para aplicação na cavidade oral
Resumo A hidroxiapatita (HAp) está presente no organismo humano nos tecidos ósseos e dentários, em que do total da massa de cada tecido 30 a 70% correspondem a HAp, podendo ser aplicada como revestimentos de próteses ou até substituição de pequenas partes ósseas. Assim, o objetivo foi sintetizar HAp por precipitação, incorporar clorexidina (CHX) e

8. A Practical Fluorescence-Based Screening Protocol for Polyethylene Terephthalate Degrading Microorganisms
We propose a practical, low-cost and selective fluorescence-based protocol adapted to identify polyethylene terephthalate (PET) degrading microorganisms. The microbial hydrolysis of PET nanoparticles was monitored by 2-hydroxyterephthalate, a fluorophore produced in situ after radical hydroxylation of terephthalic acid (TPA), the final hydrolysis product, by

9. Identification of Anti-Inflammatory and Anti-Hypertensive Drugs as Inhibitors of Bacterial Diguanylate Cyclases
Biofilms are widely present in many human chronic infections, often more resistant to treatment with antibiotics. Bacterial diguanylate cyclases (DGCs) synthesize cyclic dimeric guanosine monophosphate (c-di-GMP) from two guanosine-5'-triphosphate (GTP) molecules. c-di-GMP is a central second messenger controlling biofilm formation, turning this class of enz

10. Purification and characterization of a thermostable alkaline cellulase produced by Bacillus licheniformis 380 isolated from compost
ABSTRACT During composting processes, the degradation of organic waste is accomplished and driven by a succession of microbial populations exhibiting a broad range of functional competencies. A total of 183 bacteria, isolated from a composting process, were evaluated for cellulase activity at different temperatures (37, 50, 60, and 70°C) and pH values. Out

11. Development of a novel compound microbial agent for degradation of kitchen waste
Abstract Large quantities of kitchen waste are produced in modern society and its disposal poses serious environmental and social problems. The aim of this study was to isolate degradative strains from kitchen waste and to develop a novel and effective microbial agent. One hundred and four strains were isolated from kitchen waste and the 84 dominant strains

12. Fermentation process for production of apple-based kefir vinegar: microbiological, chemical and sensory analysis
Abstract The aim of this study was to develop a kefir apple-based vinegar and evaluate this fermentation process using new methodology with Biospeckle Laser. Brazilian kefir grains were inoculated in apple must for vinegar production. In this study, the microbial community present in kefir, and correspondent vinegar, was investigated using Matrix Assisted La
