Effects of initial microbial biomass abundance on respiration during pine litter decomposition.
PLoS ONE, 2020 IMPORTANCE:Microbial biomass is one of the most common microbial parameters used in land carbon (C) cycle models, however, it is notoriously difficult to measure accurately.

Microbial responses to doses of cover plant straw in cerrado piauiense oxisol
Bioscience Journal, 2020 Carbon and nitrogen from the soil microbial biomass play a significant role in the rotation of C and N, and promote nutrient cycling. Thus, the objective of this study was to evaluate changes in the soil microbial biomass with growing doses of cover ...

Adenosine triphosphate and microbial biomass in soil
Soil Biology and Biochemistry, 1979 Two methods for measuring adenosine 5'-triphosphate (ATP) in soil were compared, one based on extraction with NaHCO3-CHCl3 and thel other on extraction by a trichloracetic acid-phosphate-paraquat reagent. Recoveries of added ATP were greater with the NaHCO3-CHCl3 reagent but the extraction of “native” soil ATP by NaHCO3-CHCl3 was only about a third of ...

Methods for elucidating microbial biomass
IRA-International Journal of Management & Social Sciences (ISSN 2455-2267), 2016 <p>The microbial biomass of soil is defined as the part of the organic matter in the soil that constitutes living organisms smaller than the 5-10 mm<sup>3. </sup>It is generally expressed in the milligrams of carbon per kilogram of soil or micrograms of carbons per gram of dry weight of soil. Typical biomass carbon ranges from 1 to 5%
