A new Bacillus cereus phage, SWEP1, was isolated from black soil. The host lysis activity of phage SWEP1 has a relatively short latent time (20 min) and a small burst size of 83 PFU. The genome of SWEP1 consists of 162,461 bp with 37.77% G+C content. The phage encodes 278 predicted proteins, 103 of which were assigned functionally. No tRNA genes were found. Comparative genomics analysis indicated that SWEP1 is related to Bacillus phage B4 (86.91% identity, 90% query coverage). Phenotypic and genotypic characterization suggested that SWEP1 is a new member of a new species in the genus Bequatrovirus, family Herelleviridae.

新型蜡状芽孢杆菌噬菌体 SWEP1 的表型和基因型特征。

从黑土中分离出一种新的蜡状芽孢杆菌噬菌体 SWEP1。噬菌体 SWEP1 的宿主裂解活性具有相对较短的潜伏时间 (20 分钟) 和 83 PFU 的小爆发大小。SWEP1 的基因组由 162,461 bp 组成，G+C 含量为 37.77%。噬菌体编码 278 种预测蛋白质，其中 103 种被指定为功能性蛋白质。没有发现 tRNA 基因。比较基因组学分析表明，SWEP1 与芽孢杆菌噬菌体 B4 相关（86.91% 同一性，90% 查询覆盖率）。表型和基因型特征表明 SWEP1 是 Bequatrovirus 属 Herelleviridae 新物种的新成员。
