Microbial mineralisation of benzene and characterisation of microbial biomass in soil above hydrocarbon-contaminated groundwater

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...

electrokinetic remediation of a heavy metal-contaminated soil and its effect on microbial biomass-c and on microbial coefficient

use of electrokinetic technique for remediation of contaminated soils has recently been highly attended to, but there are still concerns regarding the effect of this process on soil microbial activity. in this study, changes in concentration of heavy metals extractable through 4n nitric acid, microbial biomass-c, and microbial coefficient, following electrokinetic remediation of a native soil c...

Characterizing Microbial Activity and Diversity of Hydrocarbon-Contaminated Sites

Benzene Degradation by Variovorax sp within a Coal-tar Contaminated Groundwater Microbial Community

24 Investigations of environmental microbial communities are crucial for the discovery of 25 populations capable of degrading hazardous compounds and may lead to improved 26 bioremediation strategies. The goal of this study was to identify microorganisms responsible for 27 aerobic benzene degradation in coal-tar contaminated groundwater. Benzene degradation was 28 monitored in laboratory incuba...

Diesel Degradation and Bioemulsifiers Production Using Bubble-Column with a Microbial Consortium Isolated from Hydrocarbon-Contaminated Soil

Diesel is composed of various toxic compounds that can have a negative influence on the environment including plants, microorganisms, and even groundwater being used for cultivation and human consumption. Diesel oil biodegradation kinetics was investigated using bubble-column reactor and microbial consortium isolated from a hydrocarbons spill site and were assessed<em...
