The Study of Degradation Characteristics of Isolated Pseudomonas Sp. LKY-5 on Dibenzothiophene

Abstract:

Dibenzothiophene (DBT) may seriously pollute the environment with its mutagenicity, teratogenicity and carcinogenicity. And it is recalcitrant to be degraded by microorganisms due to its low bioavailability and high hydrophobicity. In this paper, the five parameters, namely, initial concentration, temperature, pH, agitation rate and inoculum size were experimented and studied by the isolated Pseudomonas sp. LKY-5 for degradation processes. The results shown that the initial concentration of 100 mg/L, temperature of 30°C, pH of 7.5, agitation rate of 160 rpm, inoculum size of 10 % were optimal for the biodegradation of dibenzothiophene.
