polycyclic aromatic hydrocarbons (pahs) are one of the most common contaminants found in soil. pahs exhibit a significant concern because of their toxicity, carcinogenic, teratogenic and mutagenic properties. using microorganisms for cleaning the pollution of soil can be cheap, effective and can provide environmental immunity. the goal of this study is to isolate and identify phenanthrene degra...

Although there are many health advantages assigned to different live bacteria such as probiotics, some health threatening effects have also been reported. For example, live bacteria can transfer antibiotic resistance genes to other commensal and opportunistic bacteria of gastrointestinal tract. Recently, it was shown that using killed bacteria have some advantages over live ones. In this resear...

Bacillus vireti DSM 15602(T) is a Gram-negative, spore-forming, and facultatively anaerobic bacterium. Here, we report the 5.309-Mb draft genome sequence of B. vireti DSM 15602(T), which will provide useful information for setting up phylogenomics for the genomic taxonomy of Bacillus-like bacteria, as well as for the functional gene mining and application of B. vireti.
