An extraction method for measuring soil microbial biomass C
, 1987 The effects of fumigation on organic C extractable by 0.5 M K2SO4 were examined in a contrasting range of soils. EC (the difference between organic C extracted by 0.5 M K2SO4 from fumigated and non-fumigated soil) was about 70% of FC (the flush of CO2-C ...

Change in soil microbial biomass along a rural-urban gradient in Varanasi (U.P., India)
Geology, Ecology, and Landscapes, 2018 Soil microbial biomass has been used as an early indicator of change in soil properties resulting from urbanization. We analyzed the effect of urbanization along a rural–urban gradient on soil microbial biomass and physico-chemical properties of the soil.

The changes in microbial biomass C and N in long-term field experiments
Plant, Soil and Environment, 2008 Microbial biomass nitrogen and carbon were studied in long-term field experiments with continuous cultivation of silage maize and with crop rotation. A positive effect of organic fertilizers on the microbial biomass nitrogen and the carbon content in ...

Microbial biomass in paddy soil [PDF]
Soil Science and Plant Nutrition, 1984 The authors investigated the role of microorganisms in paddy soil ecosystems and the influence of fertilizer and manure applications on the soil microbial biomass in paddy soils based on direct count using a fluorescence microscope. The results are summarized as follows.

Microbial Enzymes for Biomass Conversion
Annual Review of MicrobiologyPlant biomass has emerged as a cornerstone of the global bioenergy landscape because of its abundance and cost-effectiveness. The cell wall of plant biomass is an intricate network of cellulose, hemicellulose, and lignin. The hydrolysis of cellulose and hemicellulose by holoenzymes converts these polymers into monosaccharides and paves the way for the ...

Is the thermodynamic efficiency of soil microbial communities related to ecosystem maturity and stress? [PDF]
, 2014 According to the second law of thermodynamics, no process can be 100% efficient and all processes must increase the total entropy of the system they occupy.

Measurement of microbial biomass phosphorus in soil
, 1982 A method for measuring the amount of P held in soil micro-organisms (biomass P) is described and the assumptions on which it is based are discussed. Biomass P is calculated from the difference between the amount of inorganic P (Pi) extracted by 0.5 (Spm)
