Abstract—1,3,5-TMB (trimethylbenzene) has been
considered as a priority pollutant by several environmental
agencies due to its high toxicity, carcinogenicity and mutagenic
activity. Two bacteria with ability of degrading 1,3,5-TMB
were isolated from crude oil contaminated soil. The optimal
pH value and temperature for the growth of these bacteria
were 7.0 and 30℃. 1,3,5-TMB was used as sole carbon and
energy source by both strains. Strain A was identified as
Staphylococcus sciuri and strain C was Microbacterium
schleiferi, both of which were facultative anaerobic bacteria.
1,3,5-TMB was degraded by strain C with efficiency of
41.2±1.8%. The bacteria offered new source for
biodegradation of BTEX and bioremediation of
oil-contaminated soil and groundwater.
Index Terms—1,3,5-TMB, biodegradation, facultative
anaerobic strain, Staphylococcus sciuri, Microbacterium
schleiferi.
