The objective of this work was to isolate a novel thermophilic bacterial strain and develop a bacterial consortium (BC) for efficient degradation oily food waste. Four treatments were designed: 1:1 mixture of pre-consumption food wastes (PrCFWs) and post-consumption food wastes (PCFWs) (T-1), 1:2 mixture of PrCFWs and PCFWs mixture (T-2), PrCFWs (T-3) and PCFWs (T-4). Equal quantity of BC was inoculated into each treatment to compare the oil degradation efficiency. Results showed that after 15days of incubation, a maximum oil reduction of 65.12±0.08% was observed in treatment T-4, followed by T-2 (55.44±0.12%), T-3 (54.79±0.04%) and T-1 (52.52±0.02%), while oil reduction was negligible in control. Results indicate that the development of oil utilizing thermophilic BC was more cost-effective in solving the degradation of oily food wastes and conversion into a stable end product.
本工作旨在分离一株新型嗜热细菌菌株，并开发细菌混合菌剂（BC）以有效降解含油食物废物。设计了四种处理方式：预消费食物废物（PrCFWs）和消费后食物废物（PCFWs）的 1:1 混合物（T-1）、PrCFWs 和 PCFWs 的 1:2 混合物（T-2）、PrCFWs（T-3）和 PCFWs（T-4）。将等量的 BC 接种到每个处理中，以比较油降解效率。结果表明，在 15 天的孵育后，处理 T-4 中观察到最大的油减少率为 65.12±0.08%，其次是 T-2（55.44±0.12%）、T-3（54.79±0.04%）和 T-1（52.52±0.02%），而对照中油减少可忽略不计。结果表明，开发利用油的嗜热 BC 更具成本效益，可以解决含油食物废物的降解问题，并转化为稳定的最终产物。
