NOVELTY - A plant Bacillus sp. (Strain UTM03) under preservation number (CGMCC No. 5643) is new.    USE - As plant Bacillus sp. used in sludge compost application; as thermophilic bacillus (UTM03) or yeast product or microbial inoculum for producing compost inoculating agent (claimed).    ADVANTAGE - The strain Bacillus licheniformis (UTM03) as seed compost, is good for improving the stacking biological activity, shortens the compost fermentation of the delay period, allows fast starting composting process, accelerates degradation of organic matter, reduces plant toxicity, reduces nitrogen loss, accelerates rotten accelerator for organic materials to realize the harmless, and reduces and stabilizes treatment. The compost reduces sludge compost conditioner, the usage amount of the compost cost as original seed compost, provides stable quality, and is green and environment-friendly, avoids pollution and has excellent performance; capable of avoiding the sludge compost by salt or heavy metal concentration, caused by the microorganism, which is inactivated or compost product caused by injury or heavy metal to plant super-elevation, and has better economic benefit and social benefit.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a sludge composting method involving: 1) preparing the bacteria liquid: taking the Bacillus strains according to the UTM03 inclined surface activating and expanding culture, continuously culturing to obtain bacteria liquid, 2) preparing original seed composting: preparing auxiliary material and, mixing auxiliary material and ferment bacteria liquid uniformly, composting and fermenting to obtain original seed compost, where the water content is 70-90% of sludge, 3) carrying out composting and fermenting to obtain rotten compost to obtain first level seed compost, 4) replacing first level seed compost to original seed composting for fermenting to obtain rotten compost to obtain second level seed composting, fermentation culture preparing seed compost and four-level sludge seed compost. The auxiliary material is 3-5 mm of wooden meal, straw and peanut shell.
