Rhizosphere microbial community structure in relation to root location and plant iron nutritional status

Article Abstract:

Different bacterial species will colonize the roots of plants depending on the plant's nutritional status. Different species will also be found in different parts of the root, including primary root tips, secondary root tips, lateral roots and older roots distal from the tip.

Impact of fumigants on soil microbial communities

Article Abstract:

Among several fumigants used to sterilize soil before planting crops, methyl bromide has the greatest impact on soil bacteria and 1,3-dichloropropene has the least impact. This was the conclusion of researchers who used Biolog, phospholipid fatty acid analysis, and denaturing gradient gel electrophoresis to analyze microbial populations in soil.

Plant compounds that induce polychlorinated biphenyl biodegradation by Arthrobacter sp. strain B1B

Article Abstract:

A calorimetric assay was utilized to identify plant compounds that promote the biodegradation of polychlorinated biphenyls (PBCs) by Arthrobacter sp. strain B1B. Screening of plant extracts and soil organic matter for chemicals that induce PCB cometabolism indicated the role of several plant-derived terpenoids in inducing PCB degradation. Furthermore, the highest rates of PCB biodegradation by arthrobacter were induced by plant chemicals with unsaturated para-methane structural motif.
