효소활성 자재를 이용한 음식물류 폐기물처리 공정 특성 및 미생물의 동정

Abstract

To process effectively the extinction of food waste used by enzymatic activity material, as much of enzyme, the selected excellent strains, which resolve organic matter well were put and studied the function to remove a bad smell and make food waste light. First of all, made the specific microscopic organism in soil microbe(radiation germ, yeast) revitalize and set in sawdust the result of enzymatic activity is that Bacilluscereus,Bacillusthuringiensis, Bacillussp,Serratiasubsp. etc. came to move. Bacillus andSerratia, as microorganisms, are well known for their processing food waste effectively. To identify the effect of processing food waste treatment used by enzymatic activity material of microorganism, there was a production of fermentor and studied giving different temperature, ventilation map, pH, and etc. As a result, little change caught in pH, however, approximately 20 % change caught in temperature and ventilation map. The decomposition of food waste making the use of microorganism should keep neutral pH mostly, keep 60 ℃ temperature to make the food waste light. however, in case of using enzymatic activity material of microorganism, the decomposition of food waste achieved with a good condition even in pH 4~9, and 35 ℃ temperature. Especially, only 30 % of injection of ventilation map can make decomposition efficiency outstanding. Therefore, the expenses for handling food waste would be reduced. To make the bad smell of food waste decrease, mixed and stirred enzymatic activity material and food waste was measured by gas detector. Hydrogensulfide was also decreased from 30 mg/L to 1 mg/L as a result. This experiment gives us the ability to contribute the effective disposal and odor removing of food waste. Moreover, the aspect of secure the microorganism resource for processing food waste is significance as well.
