- Abstract
- Denitrification is a crucial process for the global nitrogen cycle through the reduction of nitrates by heterotrophic bacteria. Denitrifying microorganisms play an important role in eliminating fixed nitrogen pollutants from the ecosystem, concomitant with N2O emission. Although many microbial denitrifiers have been identified, little is known about the denitrifying ability of the genus Geobacillus. Here, we report the first complete genome sequences of Geobacillus subterraneus KCTC 3922(T), isolated from Liaohe oil field in China, and G. thermodenitrificans KCTC 3902(T). The strain KCTC 3922(T) contains a complete set of genes involved in denitrification, cofactor biogenesis, and transport systems, which is consistent with a denitrifying activity. On the other hand, G. thermodenitrificans KCTC 3902(T) exhibited no denitrifying activity probably due to the lack of molybdnumtransferase (moeA) and nitrite transporter (nirC) genes. Therefore, comparative genome analysis of Geobacillus strains highlights the potential impact on treatment of nitrate-contaminated environments.
