摘  要:
为了降低猪场恶臭物质对环境的影响,从实验室保存的菌种中筛选得到4株高效除臭微生物,并研究其对猪粪便中吲哚的降解作用.结果表明,单因素粪便发酵试验筛选得到的克雷伯氏菌、贝莱斯芽孢杆菌、产朊假丝酵母和干酪乳杆菌对粪便中吲哚去除率分别为56.55%、59.12%、34.07%和53.03%(P<0.05).根据微生物之间协同关系的微生态理论,采用响应面试验设计优化微生物菌株组合模式,经响应面分析预测的各菌种最佳组合模式为克雷伯氏菌0.04%、贝莱斯芽孢杆菌0.11%、产朊假丝酵母0.59%和干酪乳杆菌0.01%,最佳组合模式下粪便吲哚去除率为62.13%.

摘  要:
In order to reduce the environment pollution from malodorous substance in pig farm, a single-factor experiment was performed by screening four species of highly effective deodorizing microorganisms. The results showed that the removal rates of indole were 56.55%, 59.12%, 34.07% and 53.03% in pig manure fermented by Klebsiella sp., Bacillus velezensis, Candida utilis and Lactobacillus casei, respectively(P<0.05). Based on the microecological theory of synergistic relationships among microbes, a response surface regression design was developed to optimize the combination of different species of microbes. And the optimal combination of the four microbial strains for pig manure fermentation was 0.04% Lebsiella sp., 0.11% Bacillus velezensis, 0.59% Candida utilis and 0.01% Lactobacillus casei. The removal rate of indole was 62.13% under the above conditions.
