Changes in soil microbial biomass with manure application in cropping systems: A meta-analysis [PDF]

, 2019
Soil microbial biomass carbon (SMBC) and nitrogen (SMBN) are important indices of soil bio-fertility. While intensively managed cropping systems can reduce microbial biomass, application of manure is a potential way to rebuilt microbial biomass and ...

Integrated Bioprocesses for Urban Food Waste: Insights into Biological Pathways, Process Integration, and Circular Economy Perspectives

Recycling
Food waste (FW) presents a critical issue, representing an environmental liability and a largely untapped resource. Its heterogeneity and low valorization rate among main-stream alternative treatments challenge its integration into economically and ...

Integrated anaerobic membrane bioreactor-yeast biorefinery for co-production of hydrogen, volatile fatty acids, and microbial oil from food waste

Scientific Reports
With growing food waste challenges globally, acidogenic fermentation using an anaerobic membrane bioreactor (AnMBR) was developed for the co-production of hydrogen, volatile fatty acids (VFAs), and microbial oil from food waste.

Microbial Biomass in Paddy Soil [PDF]

Soil Science and Plant Nutrition, 1985
The authors investigated the role of microorganisms in the paddy soil ecosystem and the influence of fertilizer and manure application on the soil “microbial biomass” in paddy soils using Jenkinson’s fumigation method. The results obtained are summarized as follows.

Modelling soil organic matter turnover [PDF]

, 2004
This thesis investigates various ways of determining and predicting soil carbon quality. The continuous-quality theory was used to study soil carbon quality changes under perturbations and to explain soil C:N ratios. Also, using the framework of the same

Effect of cytostatic drugs on microbial behaviour in membrane bioreactor system [PDF]

, 2010
The aim of this work is to evaluate the influence of cyclophosphamide and its principal metabolites (CPs) on microbial behaviour in a membrane bioreactor system. Two laboratory-scale membrane bioreactors (MBR) were run in parallel with a sludge retention

Sources of nitrogen for winter wheat in organic cropping systems [PDF]

, 2013
In organic cropping systems, legumes, cover crops, residue incorporation, and manure application are used to maintain soil fertility, but the contributions of these management practices to soil nitrogen (N) supply remain obscure.
