PURPOSE: Novel bacillus khr-10-mx gene, a clean emulsion expressed from the gene, and an additive composition for liquid fuel containing the clean emulsion for inducing reduction of harmful gas are provided, which can increase octane value of internal combustion engine for preventing abnormal combustion of internal combustion engine, so that output power, torque and fuel efficiency are enhanced, and emission of air pollutants such as CO, HC, NOx is reduced. CONSTITUTION: The additive composition for liquid fuel is characterized in that it comprises 10 to 50 wt.% of at least two kinds of aliphatic alcohol having 2 to 11 of hydrocarbon; 10 to 50 wt.% of at least one kind of unsaturated or saturated hydrocarbon; 10 to 30 wt.% of at least one kind of ether having two cyclic hydrocarbon radical of less than 6 of carbon atom, the ether being at least one kind selected from a group consisting of methyl t-butyl ether (MTBE), t-amyl methyl ether (TAME) or t-butyl ether. The additive composition is used by mixing with biological clean dispersant at a weight ratio of 0.01 to 1 of the dispersant to the additive composition. The biological clean dispersant is prepared by cultivating as a strain at least more than one selected from a group consisting of bacillus khr-10-mx (KCTC 8533P) and khr-5-mx (KCTC 0078BP) at 5x10¬8 CFU/ml to 5x10¬9 CFU/ml, followed by separation and purification. |
