(formerly ) is a gram-positive, aerobic, spore-forming bacterium found in a wide range of environmental niches. Here, we report the complete genome sequence of S188 isolated from soil, which can decrease hydrogen sulfide (HS) levels and help reduce malodor generation in livestock farms. Putative genes related to sulfide assimilation and conversion were found in the genome of 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 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 HS reduction would facilitate the optimization of the HS-degrading ability of S188.
（以前）是一种革兰氏阳性、需氧、产芽孢的细菌，存在于广泛的环境生态位中。在此，我们报告了从土壤中分离出的S188的完整基因组序列，它可以降低硫化氢（HS）水平，并有助于减少畜牧场中的恶臭产生。在S188的基因组中发现了与硫化物同化和转化相关的推定基因；其中，鉴定出一种O-乙酰高丝氨酸（O-AH）脱硫酶、两种主要与含硫氨基酸生物合成相关的半胱氨酸合酶、五种硫氰酸酶或硫转移酶以及一种氮还原酶。关于S188的基因组信息为导致恶臭的含硫物质的可能生物降解或转化机制提供了见解，这有助于减少气味产生。此外，鉴定负责HS还原的关键基因或分子将有助于优化S188的HS降解能力。
