The whole genome sequence (WGS) of Bacillus coagulans BCP92 is reported along with its genomic analysis of probiotics and safety features. The identification of bacterial strain was carried out using the 16S rDNA sequencing method. Furthermore, gene-related probiotic features, safety assessment (by in vitro and in silico), and genome stability were also studied using the WGS analysis for the possible use of the bacterial strain as a probiotic. From the BLAST analysis, bacterial strain was identified as Bacillus (Heyndrickxia) coagulans. WGS analysis indicated that the genome consists of a 3 475 658 bp and a GC-content of 46.35%. Genome mining of BCP92 revealed that the strain is consist of coding sequences for d-lactate dehydrogenase and l-lactate dehydrogenases, 36 genes involved in fermentation activities, 29 stress-responsive as well as many adhesions related genes. The genome, also possessing genes, is encoded for the synthesis of novel circular bacteriocin. Using an in-silico approach for the bacterial genome study, it was possible to determine that the Bacillus (Heyndrickxia) coagulans strain BCP92 contains genes that are encoded for the probiotic abilities and did not harbour genes that are risk associated, thus confirming the strain's safety and suitability as a probiotic to be used for human application.
报道了凝结芽孢杆菌BCP92的全基因组序列(WGS)及其益生菌和安全性特征的基因组分析。使用16S rDNA测序方法对细菌菌株进行鉴定。此外,还通过WGS分析研究了与基因相关的益生菌特征、安全性评估(体外和计算机模拟)以及基因组稳定性,以确定该细菌菌株作为益生菌的潜在用途。通过BLAST分析,该细菌菌株被鉴定为凝结芽孢杆菌(海恩德里克氏菌属)。WGS分析表明,该基因组由3475658个碱基对组成,GC含量为46.35%。对BCP92的基因组挖掘显示,该菌株包含d-乳酸脱氢酶和l-乳酸脱氢酶的编码序列、36个参与发酵活动的基因、29个应激反应相关基因以及许多与黏附相关的基因。该基因组还拥有编码新型环状细菌素合成的基因。通过计算机模拟方法对细菌基因组进行研究,可以确定凝结芽孢杆菌(海恩德里克氏菌属)菌株BCP92含有编码益生菌能力的基因,且不含有与风险相关的基因,从而证实了该菌株作为用于人类的益生菌的安全性和适用性。
