Chicken manure containing antibiotics is a hazardous biological waste. The purpose of our study was to investigate how different concentrations of penicillin G alter the bacterial community to affect humification during aerobic composting of chicken manure. The effect of quorum sensing on the bacterial community was also evaluated. Penicillin G mainly affects low fold changes (within 4) for low-abundance (within 200) microbial genera. We found that the bacterial community cooperated to regulate humus and humic acid synthesis. The microbial genera that make up the bacterial community are different, but each bacterial community may have the same ecological function. Quorum sensing affects humic acid synthesis by regulating carbohydrate metabolism and amino acid metabolism in bacterial communities through mechanisms such as the pentose phosphate pathway and the shikimate pathway. This work presents an understanding of the impact of quorum sensing on the collaboration between bacterial communities during composting.
鸡粪中含有抗生素，是一种危险的生物性废物。本研究旨在探讨不同浓度青霉素 G 如何改变细菌群落，从而影响鸡粪好氧堆肥过程中的腐殖化。同时还评估了群体感应对细菌群落的影响。青霉素 G 主要影响低丰度（低于 200）微生物属中低折叠变化（低于 4）。我们发现细菌群落合作调节腐殖质和腐殖酸的合成。构成细菌群落的微生物属不同，但每个细菌群落可能具有相同的生态功能。群体感应通过戊糖磷酸途径和莽草酸途径等机制调节细菌群落中的碳水化合物代谢和氨基酸代谢，从而影响腐殖酸的合成。这项工作阐明了群体感应对堆肥过程中细菌群落协同作用的影响。
