Soil contamination with petroleum hydrocarbon products such as diesel and engine oil is becoming one of the major environmental problems. This study describes hydrocarbons degrading bacteria (PHAD) isolated from long-standing petrol polluted soil from the eastern region, Dammam, Saudi Arabia. The isolated strains were firstly categorized by accessible shape detection, physiological and biochemistry tests. Thereafter, a technique established on the sequence analysis of a 16S rDNA gene was used. Isolation of DNA from the bacterial strains was performed, on which the PCR reaction was carried out. Strains were identified based on 16S rDNA sequence analysis, As follows amplified samples were spontaneously sequenced automatically and the attained results were matched to open databases. Among the isolated bacterial strains, S1 was identified as Staphylococcus aureus and strain S1 as Corynebacterium amycolatum.
柴油和机油等石油烃类产品对土壤的污染正成为主要的环境问题之一。本研究描述了从沙特阿拉伯达曼东部地区长期受汽油污染的土壤中分离出的烃降解细菌(PHAD)。首先通过可及形态检测、生理生化试验对分离出的菌株进行分类。此后,使用了一种基于16S rDNA基因序列分析的技术。从细菌菌株中提取DNA,并在其上进行PCR反应。基于16S rDNA序列分析对菌株进行鉴定,如下所述,扩增后的样品自动进行自发测序,并将所得结果与开放数据库进行比对。在分离出的细菌菌株中,菌株S1被鉴定为金黄色葡萄球菌,菌株S2被鉴定为无枝菌酸棒状杆菌。 (注:原文中关于菌株S1的描述重复且有误,译文按纠正后的内容“菌株S2”进行翻译)
