| Summary: | Priestia megaterium (formerly Bacillus megaterium) is a gram-positive, aerobic, spore-forming bacterium found in a wide range of environmental niches. Here, we report the complete genome sequence of P. megaterium S188 isolated from soil, which can decrease hydrogen sulfide (H2S) levels and help reduce malodor generation in livestock farms. Putative genes related to sulfide assimilation and conversion were found in the genome of P. megaterium S188; among these, one O-acetylhomoserine (O-AH) desulfhydrase, two cysteine synthases-primarily related to the biosynthesis of sulfur-containing amino acids, five rhodanese or sulfurtransferases, and one nitrogen reductase were identified. The genomic information on P. megaterium S188 provides insights into the possible biodegradation or conversion mechanisms of sulfur-containing substances that cause malodors, which can help reduce odor generation. Furthermore, identification of the key genes or molecules responsible for H2S reduction would facilitate the optimization of the H2S-degrading ability of S188. |
