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 alginate oligosaccharides treatment on preservation and fresh-keeping mechanism of shrimp during frozen storage
Abstract In this study, we investigated the influence of alginate oligosaccharides (AOS) coating on the quality of white shrimp (P. vannamei) at 4 ± 1 °C. We measured shrimp quality by surveying changes in certain properties, such as sensory quality, the microbiota, total volatile basic nitrogen (TVB-N), pH, and sensory characteristics. Compared to control

3. Free-living diazotrophs drive castor bean nitrogen input in tropical semiarid soils
RESUMO: Existem poucos estudos sobre a diversidade microbiana em solos de mamona no ambiente semiárido tropical. Os produtos de mamona têm sido amplamente utilizados em todo o mundo e justificam a importância comercial da ricinocultura no semiárido nordestino brasileiro. Como não há qualquer tipo de fertilização, ou manutenção de resíduos da cult

4. Sugarcane inoculated with endophytic diazotrophic bacteria: effects on yield, biological nitrogen fixation and industrial characteristics
Abstract: The growing need for the use of clean energy has led society to seek alternatives to fossil fuels in order to less pollute the environment. Sugarcane has been known to produce enough biomass and to have associative microorganisms, such as plant growth-promoting bacteria (PGPB), which have the potential to improve the yield of crops. The objective

5. Red clover silage: an alternative for mitigating the impact of nitrogen excretion in ovine production systems
ABSTRACT The objective was to quantify the flow of intestinal nutrients and nitrogen excretion and retention in sheep receiving isoproteic diets. Eight Texel x Lacaune wethers (average body weight = 25±2.5 kg) were fitted with duodenal cannula and housed in metabolic cages. Wethers were assigned to the treatments in a crossover design with two periods of 20

6. Cover cropping system and mulching can shape soil microbial status in fruit orchards
ABSTRACT The use of cover crop in agricultural fields has been well elucidated, especially regarding nitrogen fixation from legume crops and their function as weed protection. Furthermore, to cover crops can benefit the soil microbial community. This study aimed to evaluate and compare the benefits of mulching and cover cropping systems on soil microbial gro

7. Microbial Properties of Soil in Different Coverages in the Colombian Amazon
ABSTRACT Changes in coverage affect the activity of soil’s microbial communities, affecting the carbon and nitrogen cycle. The variability of biochemical properties in different coverages (native forest, forest plantation, silvopastoral system and pasture) located in the northwest of the Colombian Amazon was evaluated. Edaphic properties were determined as

8. Soil Microbial Biomass as an Edge Effect Indicator in Semi-Deciduous Seasonal Forest Fragments
ABSTRACT This work had the objective to evaluate the activity and microbial biomass of the soil as an indicator of edge effect in Semi-Deciduous Seasonal Forest fragments. Three fragments of different sizes (small, medium and large) located in the Southwest region of Bahia state were evaluated, in which three sampling ranges were defined in each, and soil sa

9. Effects of trees and nitrogen supply on the soil microbiological attributes on integrated crop-livestock systems
ABSTRACT The diversification of plants, as an association between trees and the warm-season grasses, supports soil biodiversity and thus, soil quality. However, based on the prevailing climatic conditions, management techniques employed and because of the several combinations possible in such associations, variations may be observed in this type of respons

10. VALORIZATION OF SOLID WASTES FROM THE BREWERY AND BIODIESEL INDUSTRIES FOR THE BIOPRODUCTION OF NATURAL DYES
This study aims to assess a new approach for concomitant valorization of two industrial wastes - raw glycerin and spent brewer’s yeast - for the bioproduction of valuable carotenoids. Microbial pigments have numerous applications in the food and cosmetic industries. First, four cultures of yeasts were screened using pure glycerol and either (NH4)2SO4 or ur

11. Soil quality indicators after conversion of “murundu” fields into no-tillage cropping in the Brazilian Cerrado
Resumo: O objetivo deste trabalho foi avaliar as alterações na qualidade do solo devido a diferentes tempos de adoção do sistema plantio direto em campos de murundus convertidos para agricultura, bem como identificar quais seriam os melhores indicadores para explicar essas alterações. O estudo foi realizado em Plintossolo Háplico, no Município de Por

12. 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)
