Microbial community structure in a silty clay loam soil after fumigation with three broad spectrum fungicides
(Taylor & Francis, 2008-04)
The short-term effect of three broad spectrum fungicides on microbial activity, microbial biomass, soil ergosterol content, and phospholipid fatty acid (PLFA) profiles was studied. A silty clay loam soil was treated ...
Tannery sludge compost amendment rates on soil microbial biomass of two different soils
(Elsevier France-editions Scientifiques Medicales Elsevier, 2011-03-01)
Composting is recognized as one of the most cost-effective and environmentally sound alternatives for organic waste recycling. Long-composted wastes have the potential to substitute for inorganic fertilizers. We investigated ...
Lead distribution in organic matter of loamy oxisol treated with manure and its effect on microbial biomass
(Marcel Dekker Inc, 2001-01-01)
This paper reports a study regarding the distribution of lead in the organic matter fractions of a loamy oxisol treated with stable manure, and its effect on the soil microbial biomass. The experimental design was a ...
Three decades of soil microbial biomass studies in Brazilian ecosystems: lessons learned about soil quality and indications for improving sustainability.
(Soil Biology & Biochemistry, Oxford, v. 42, p. 1-13, 2010., 2010)
Biotechnological Utilization of Biodiesel-Derived Glycerol for the Production of Ribonucleotides and Microbial Biomass
(HUMANA PRESS INCTOTOWA, 2012)
Ten yeast strains were evaluated concerning their capabilities to assimilate biodiesel-derived glycerol in batch cultivation. The influence of glycerol concentration, temperature, pH and yeast extract concentration on ...
A new approach to determine soil microbial biomass by calorimetry
(Springer, 2011-04)
A method to determine soil microbial biomass (SMB) by isothermal calorimetry is reported. Soil samples ranging in pH from 6.2 to 9.4 and different textures were used to develop the method. Soil at 60% of its field capacity ...
Microbial populations and activities in sewage sludge and phosphate fertilizer-amended soil
(Elsevier B.V., 1996-07-01)
A greenhouse study was conducted to determine the number of microbial populations and activities in sewage sludge and phosphate fertilizer-amended dark red latosoil for cultivation of tomato plants. Sewage sludge was applied ...
Humic fractions of forest, pasture and maize crop soils resulting from microbial activity
(Sociedade Brasileira de Microbiologia, 2014-09-01)
Humic substances result from the degradation of biopolymers of organic residues in the soil due to microbial activity. The objective of this study was to evaluate the influence of three different ecosystems: forest, pasture ...
