CHARACTERISTICS OF FACULTATIVE ANAEROBIC BACTERIUM STRAIN BDNS3 ISOLATED FROM HERBICIDEIDIOXIN CONTAMINATED SOIL IN DANANG AIRPORT AREA

Abstract

The facultative anaerobic bacterial strain BDNS3 was isolated from mixture of two soil samples that collected in "active landfill" biotreatment field experiments 10DNT and 100DNT for detoxification of herbicide/dioxin contaminated soil in former US military base in Danang airport area, by enrichment procedure. Bacterial strain BDNS3 was able to grown in SH I medium suppJied with dioxin containing soil extracted solution and produce H2S gas. The cells of BONS3 strain are Gram negative and short rod sharpe, no flagel1a and evarage size is 3 flm x 0.84 l.un. Based on morphological characteristics and analysis of partial sequence of 168 rRNA gene, BDNS3 bacterial strain should be placed in genus Bacteroides and named as Bacteroides sp. BDNS3. The nucleotide sequence of 168 rRNA gene fragment ofBDNS3 bacterial strain was deposited in GenBank with assession number FJl884l2
