초록

휘발성 황화합물 중 생물학적으로 가장 난분해성으로 알려 져 있는 DMS에 대한 분해능이 우수한 신균주를 분리. 동정 하여 Gordonia sihwaniensis PKL-1로 명명하였다. 이 균주는 D DMS 초기농도가 35 mg/L 이상일 때에도 우수한 분해능을 보였고, 회분식 배양에서 최대 비분해속도 $\upsilon_{max}$ 없는 0.0016 mg/(mg-protein).hr이 었고, 최적 의 온도와 pH는 각각 $25^{\circ}C$ 와 pH는 7이였다.

Biodegradation of dimethyl sulfide (DMS) was studied in a batch culture using Gordonia sihwaniensis PKL-1 isolated from a compost biofilter after 100 days of operation for the removal of volatile organic compounds. Optimal pH and temperature for the removal of DMS were 7 and $25^{\circ}C$, respectively. The Michaelis-Menten kinetic constants for DMS removal, $\upsilon_{max}$ and $K_s$, were 0.0016 mg/(mg-protein)ㆍhr, and 8.05 mg/L, respectively.
