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 3922T, isolated from Liaohe oil field in China, and G. thermodenitrificans KCTC 3902T. The strain KCTC 3922T 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 3902T 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.

The genus Serratia incorporates many agriculturally important species. Serratia fonticola strain GS2, isolated from a sesame rhizosphere, can produce N -acyl homoserine lactone quorum sensing signal molecules and indole-3-acetic acid (IAA). Here we report the complete genome sequence and phenotypic characteristics based on genomic information of this bacterium. The complete genome sequence of S. fonticola strain GS2 consists of a chromosome of 6.1 Mbp and two plasmids of 132 kbp and 94 kbp. The genome clusters for IAA and N -acyl homoserine lactone biosynthesis were identified in the genome. Subsequently, the Salkowski test and gas chromatography-mass spectrometry (GC–MS) analysis also revealed that the strain GS2 produces indolic compounds (27.1 μg mL −1 ) and IAA (6.7 μg mL −1 ) in its culture broth. HPLC analysis confirmed that the strain GS2 produced the quorum sensing signal molecules N -hexanoyl- L -homoserine lactone and N -octanoyl- L -homoserine lactone. This new information on the genome sequence and phenotype features will inform future ecological studies related to plant-microbe interactions.
