Abstract

Malodor emitted while producing fertilizer from hatchery egg waste treated with microorganism is an important limiting factor. To reduce this problem, we attempted to use two yeast strains, Saccharomyces cerevisiae, KACC 30008 and KACC 30068. Both yeast strains reduce ammonia gas emission 35.4% than only treated with bacterium, Bacillus amyloliquefaciens. When both strains were used together, that was reduced as 57.1%. KACC 30008 and 30068 strains reduced hydrogen sulfide 42 and 90.4%, respectively. Both strains together reduced hydrogen sulfide gas as 98.5%. KACC 30008 did not decrease methyl mercaptan emission. However KACC 30068 decreased 40% and both strains together decreased the gas emission as 66.7%. Overall, this study showed that yeast treatment could enhance the effect of B. amyloliquefaciens treatment in the reduction of malodorous gas emission.

부화장에서 폐기하는 달걀을 Bacillus amyloliquefaciens를 이용 분해하여 비료화하는 데 있어 발생하는 악취는 폐기물 처리에 있어 중요한 제한요소 중 하나이다. 이런 문제를 해결하기 위하여 두 개의 효모, Saccharomyces cerevisiae KACC 30008와 KACC 30068를 사용하여 실험하였다. 효모 균주는 모두 세균만을 사용하여 분해 처리하였을 때보다 섞어서 사용한 경우 암모니아 발생을 약 35.4% 감소하였고, 두 균주를 같이 섞어 사용한 경우는 57.1% 감소시켰다. 두 균주는 황화수소 또한 42%와 90.4%씩 각각 감소시켰고, 동시에 두 균주를 같이 사용했을 때에는 황화수소 발생을 98.5% 감소시켰다. 메틸메르캅탄의 경우 KA30008은 감소시키지 못하였으나 KA30068은 40%, 두 균주를 함께 사용한 경우는 66.7% 감소시켰다. 전체적으로 본 연구는 효모의 처리가 B. amyloliquefaciens를 사용하여 폐달걀 분해 시 악취 발생을 저감하는 효과를 더 증진시킴을 보여주었다.
