Detection of bphAa gene expression of Rhodococcus sp. strain RHA1 in soil using a new method of RNA preparation from soil.

To understand the response of soil bacteria to the surrounding environment, it is necessary to examine the gene expression profiles of the bacteria in the soil. For this purpose, we developed a new method of extracting RNA from soil reproducibly. Using this new method, we extracted RNA from a field soil, which was sterilized and inoculated with Rhodococcus sp.

Impacts of bioremediation schemes on bacterial population in naphthalene-contaminated marine sediments.

Microcosm experiments were conduced in which the surface of marine sediment was contaminated with naphthalene and subjected to either of three different bioremediation schemes, i.e., biostimulation (BS) by supplementing with slow-release nitrogen and phosphorus fertilizers, bioaugmentation (BA) by inoculating with Cycloclasticus sp.
