Abstract

Sphingomonas subarctica T7b was isolated from soil in Toyotomi, Hokkaido, Japan as an
organism capable of desulfurizing aromatic hydrocarbons in light gas oil (LGO) through enrichment
culture. S. subarctica T7b could grow on mineral salt sulfur-free (MSSF) medium with the
n-tetradecane oil phase containing dibenzothiophene (DBT), alkyl dibenzothiophenes (alkyl DBTs)
or alkyl benzothiophenes (alkyl BTs) as the sole sulfur source and desulfurize these compounds,
but could not utilize the tetradecane as a carbon source. This is the first report of a gram-negative
bacterium which can desulfurize 4,6-dibutyl DBT and 4,6-dipentyl DBT. The desulfurized product
of DBT produced by this strain was 2-hydroxybiphenyl, as in the case of other DBT-desulfurizing
bacteria. S. subarctica T7b could desulfurize LGO and the sulfur content was decreased to
41% within 36 h.
