title: [Diversity of culturable butane-oxidizing bacteria in oil and gas field soil].
abstract: Butane-oxidizing bacteria in soil sample sites from Puguang gas field in Sichuan province and Jianghan oil field in Hubei province were isolated and 16S rRNA gene sequence and phylogenetic analysis were applied. The differences of number and phylogenetic position and population diversity of hydrocarbon-oxidizing bacteria in different environment were investigated. The results show that 25 strains of butane-oxidizing bacteria were isolated. Based on sequencing of 16S rRNA gene, the species of bacteria in two samples are classified into 3 phyla including Firmicutes, Actinobacteria and Proteobacteria. The community structure of butane-oxidizing bacteria isolated from two oil samples is simple, both of them contain 4 genus including Bacillus, Pseudomonas, Rhodococcus and Arthrobacter. Strains in the genus of Ochrobactrum and Mycobacterium were only isolated from Puguang gas field. The number and population diversity of butane-oxidizing bacteria in Puguang gas field was more than those in Jianghan oil field.
