通过将采集的猪粪经过堆肥试验,再通过菌株的分离与菌株的初筛,利用臭味六级分类法筛选出20株菌株。然后,经过菌株的复筛试验,利用硼酸溶液吸收法和亚甲基蓝法共筛选出2株去除硫化氢和氨气效果较好的菌株,分别是枯草芽孢杆菌和班图酒香酵母菌。其中,除臭效果最佳的是班图酒香酵母菌,除臭率高达45%,在改善养殖环境中具有重要的应用前景。 By collecting the pig manure compost test, and then through the separation of strains and preliminary screening of strains, the use of stinky six-class classification of 20 strains. Then, after the rescreening test of the strains, two strains which were better to remove hydrogen sulfide and ammonia were screened out by the method of absorption of boric acid solution and methylene blue, which were Bacillus subtilis and Bantu sage respectively. Among them, the best deodorant effect is Bantu wine yeast with a deodorization rate of up to 45%, which has an important application prospect in improving the culture environment.
