Abstract: Provided is microbial materials for degradation of oils and toxic chemicals. The microbial material comprises (a) a microorganism and culture filtrate capable of degrading oil and toxic chemicals being at least one selected from the group consisting of Trichosporon loubieri Y1-A of deposit No. KCTC 10876BP, Trichosporon cutaneum, and white-rot fungi living upon the surface of wood, (b) rapeseed oils for producing more sophorolipid in surface of the said microorganism, (c) lipophilic powder being at least one selected from the group consisting of natural wax, synthetic wax, beeswax and waste candle, and (d) a microbial nutrient. This invention further comprises (e) the Bacillus subtilis of Deposit No. KCCM 10639 and the Bacillus subtilis of Deposit No. KCCM 10640. The microbial material can efficiently, rapidly degrade contaminants that are unreadily degradable, by increasing a contact area with the microorganism capable of degrading the unreadily degradable contaminants.

Abstract: The present invention relates to a composition for controlling plant diseases, which comprises novel bacterial strain Bacillus strain KCCM 10639 or KCCM 10640, and a method for controlling plant diseases using said bacterial strain. More particularly, the invention relates to a pure culture of novel bacterial strain Bacillus subtilis KCCM 10639, KCCM 10640 or a mixture thereof, a microbial formulation containing said pure culture as an active ingredient, and a method for controlling plant diseases using said pure strain or bacterial microorganism.
