Microbial community changes in a perturbed agricultural soil investigated by molecular and physiological approaches
Article Abstract:
Physiological and molecular approaches were used to investigate the response of bacterial communities in the soil to anaerobic and methane-enriched atmosphere. Methanotrophic and methylotrophic activities were likewise studied. Shifts in community structure and physiology were noted following gas perturbation. In addition, genetic analysis of the bacterial community found the diversity and enrichment of methanotrophs to be reduced following perturbation.

Treating soil solution samplers to prevent microbial removal of analytes
Article Abstract:
The accuracy of soil water data is affected by the microbial population present in sampling devices such as lysimeters. The microorganisms adsorbed nonbio- and biodegradable organic chemicals passing through the porous ceramic walls which results in concentration reading lower than the surrounding soil water. However, the accuracy of the reading improved with addition of either sodium hypochlorite or copper salt which eliminated microbial activity.

Removal of dibenzofuran, dibenzo-p-dioxin, and 2-chlorodibenzo-p-dioxin from soils inoculated with Sphingomonas sp. strain RW1
Article Abstract:
Addition of the Sphingomonas sp strain RW1 affects the removal of dibenzofuran, dibenzo-p-dioxin and 2-chlorodibenzo-p-dioxin from soil microcosms to final concentrations in the parts-per-billion range. Specifically, the density of RW1 organisms influences the rates and extents of removal. The rate of removal for 2-chlorodibenzo-p-dioxin depends on the content of soil organic matter, with half-life values between 5.8 h and 26.3 h.
