This paper investigated the effect of co-composting of lincomycin mycelia dregs (LMDs) with furfural slag on the degradation of lincomycin, maturity and microbial communities. Results showed that after 66 days composting, the concentration of lincomycin was removed above 99%. The final pH, C/N and germination index (GI) all met the national standards in maturity. Enumeration of total cultivable microbes showed the composting process was not inhibited by the addition of LMDs. Microbial diversity suggested that co-composting was beneficial to increase the abundance and diversity of bacterial communities for LMDs' treatment. Canonical correlation analysis (CCA) indicated the bacteria communities were strongly affected by residual lincomycin, with lincomycin reduced greatly, microbial communities of T and CK became similar at the end of composting. The potential bacteria to degrade lincomycin were Anaerococcus, Peptostreptococcus, and Lactobacillus. Based on these results, this research indicated that the co-composting was a feasible treatment for LMDs.
本文研究了林可霉素菌丝渣(LMDs)与糠醛渣共堆肥对林可霉素降解、成熟度和微生物群落的影响。结果表明,堆肥 66 天后,林可霉素的浓度去除率超过 99%。最终的 pH 值、C/N 比和发芽指数(GI)均符合成熟度的国家标准。总可培养微生物的计数表明,添加 LMDs 并没有抑制堆肥过程。微生物多样性表明,共堆肥有利于增加细菌群落的丰度和多样性,从而有利于 LMDs 的处理。典范对应分析(CCA)表明,细菌群落受残留林可霉素的强烈影响,随着林可霉素的大量减少,T 和 CK 的微生物群落在堆肥结束时变得相似。降解林可霉素的潜在细菌为厌氧球菌、消化链球菌和乳酸杆菌。基于这些结果,本研究表明共堆肥是 LMDs 的一种可行处理方法。
