Abstract

Exploration of bioactive compounds from endophytic bacteria as novel source of antibacterial need to be explored, as an alternative to substitute synthetic antibiotics. Based on previous studies, DM6 was a potential isolate that showed antibacterial activity. The isolate has been identified as Brevibacillus sp. based on 16S rRNA analysis. This study aimed to identify antibacterial compounds produced by DM6 isolate using GC-MS. The GC-MS results showed that the chloroform extract of DM6 isolate contained : 1-Octadecene (CAS).alpha.-Octadecene, Hexanedioic acid, dioctyl ester (CAS) Dioctyl adipate, Phenol, 3,5-bis(1,1-dimethylethyl)- (CAS) 3,5-Di-tert-butylphenol, and 1,4-diaza-2,5-dioxobicyclo[4.3.0]nonane. Adipic acid/hexanedioic acid and phenols are also known to contained in the leaves of Coleus scutellariodes. This indicated that endophytic bacteria were able to synthesize antibacterial compounds which similar with the host plant.
用气相色谱-质谱法分析棉麻叶内生细菌代谢产物的化合物谱
从内生细菌中寻找具有生物活性的化合物,作为新的抗菌药物来源,作为合成抗生素的替代品,有待于进一步探索。根据以往的研究,DM6是一种具有抗菌活性的潜在分离物。经16S rRNA鉴定为短芽孢杆菌属。本研究旨在利用GC-MS鉴定DM6分离物产生的抗菌化合物。GC-MS结果表明,DM6分离物的氯仿提取物中含有:1-十八烯(CAS)。-己二酸十八烯二辛酯(CAS)己二酸二辛酯,苯酚,3,5-二(1,1-二甲基乙基)- 3,5-二叔丁基苯酚,1,4-重氮-2,5-二氧双环壬烷[4.3.0]。众所周知,黄花Coleus scutellariodes的叶子中也含有己二酸/己二酸和酚类物质。这表明内生细菌能够合成与寄主植物相似的抗菌化合物。
