A strain, named BBB-01, was isolated from rice shoots based on the confrontation plate assay activity against several plant pathogenic fungi. The genome of this bacterial strain consists of two circular chromosomes and one plasmid with 8,201,484 base pairs in total. Pangenome analysis of 23 strains suggests that BBB-01 has the closest evolutionary relationship to pv. and pv. . BBB-01 emitted dimethyl disulfide and 2,5-dimethylfuran when it was cultivated in lysogeny broth and potato dextrose broth, respectively. Dimethyl disulfide is a well-known pesticide, while the bioactivity of 2,5-dimethylfuran has not been reported. In this study, the inhibition activity of the vapor of these two compounds was examined against phytopathogenic fungi, including , , , and , and human pathogen . In general, 2,5-dimethylfuran is more potent than dimethyl disulfide in suppressing the growth of the tested fungi, suggesting that 2,5-dimethylfuran is a potential fumigant to control plant fungal disease.
一种名为 BBB-01 的菌株是根据对几种植物病原真菌的对峙平板测定活性从水稻芽中分离出来的。该细菌菌株的基因组由两个圆形染色体和一个质粒组成，总共有 8,201,484 个碱基对。对 23 株菌的泛基因组分析表明，BBB-01 与 pv. 和 pv. 具有最密切的进化关系。当 BBB-01 在溶菌肉汤和马铃薯葡萄糖肉汤中培养时，分别发出二甲基二硫醚和 2,5-二甲基呋喃。二甲基二硫醚是一种著名的杀虫剂，而 2,5-二甲基呋喃的生物活性尚未报道。在这项研究中，检测了这两种化合物的蒸气对植物病原真菌（包括 、 、 、 和 以及人类病原体 ）的抑制活性。总的来说，2,5-二甲基呋喃比二甲基二硫醚更能抑制测试真菌的生长，这表明 2,5-二甲基呋喃是一种潜在的熏蒸剂，可以控制植物真菌病。
