Industrial and urban organic wastes increase soil microbial activity and biomass

Soil Microbial Biomass Determination

Basic Idea: The quantity of microbial biomass in a given soil sample is inherently difficult to measure. To some degree, any measurement of microbial biomass is relative – different methodologies or variations in methodologies will yield microbial biomass estimates that are not directly comparable. For this reason, if you want to measure microbial biomass – choose a method and stick with it exa...

Heavy metal Impact on Soil Microbial Biomass , Soil dehydrogenase activity and Soil Respiration rate

The contamination of agricultural soils by heavy metals is a global problem. Soil texture as a biotic factor represents one of the most important factors that influences the distribution of organic matter and ultimately play decisive role in retention of heavy metals in soil ecosystem. The effects of heavy metals on soil microbial processes were investigated. Analytical grade sulphate and chlor...

Effects of sulfonamide and tetracycline antibiotics on soil microbial activity and microbial biomass.

Increasingly often soil residual concentrations of pharmaceutical antibiotics are detected, while their ecotoxic relevance is scarcely known. Thus, dose related effects of two antibiotics, sulfapyridine and oxytetracycline, on microorganisms of two different topsoils were investigated. The fumigation-extracted microbial C (E(C)) and ergosterol were determined to indicate soil microbial and fung...

Supercritical Water Gasification of Biomass and Organic Wastes

With the exhaustion of fossil fuels and the severe pollution of the environment, it’s urgent to find substitute renewable energy resources. Biomass is a kind of widespread and abundant renewable resource with lower sulfur content than fossil fuels, so the pollution to environment from biomass usage is much slighter than that from fossil fuels usage. Besides, zero emission of CO2 can be realized...
