Description

Twenty-eight strains of aerobic chemoheterotrophic bacteria capable of decomposing methanethiol and hydrogen sulfide were isolated from soil samples obtained from mountains, forests, farm fields, parks, hot springs, riversides, the seashore, pigpens, cowsheds, henhouses and other areas in Japan. Among the strains isolated, TOS-35 and TOS-55 had the greatest activities against both methanethiol and hydrogen sulfide. Based on physiological traits, strain TOS-35 was identified as a member of the genus Alcaligenes and strain TOS-55 as that of the genus Pseudomonas. Some authentic strains such as Pseudomonas putida IFO 3738, Comamonas testosteroni IFO 12048, Brevundimonas diminuta IFO 14213 and Burkholderia cepacia IFO 14595 were found to be capable of oxidizing methanethiol and hydrogen sulfide. Our results showed that many species of chemoheterotrophic bacteria in nature are capable of decomposing organic and inorganic sulfur compounds.
