Co-culture of Bacillus coagulans and Candida utilis was firstly investigated in the efficient treatment of Lactobacillus fermentation wastewater (LFW) containing total organic carbon (TOC) of 22.0 g/L and total nitrogen (TN) of 2.4 g/L. The utilization of lactic acid by C. utilis was responsible for the relief of feedback inhibition to promote the growth of B. coagulans. The removal ratio of TOC by B. coagulans and C. utilis was only 9.1% and 22.7%, respectively, which was improved to 49.0% by co-culture. The removal ratio of TN by B. coagulans and C. utilis was merely 6.3% and 12.5%, respectively, which was also promoted to 44.6% by co-culture. Both the high growth of B. coagulans and the efficient removal of TOC and TN from LFW was achieved with the co-culture, which is not previously reported and very important in the production of probiotics with the resource utilization of LFW.
首次研究了凝结芽孢杆菌和产朊假丝酵母的共培养在高效处理总有机碳（TOC）为22.0 g/L、总氮（TN）为2.4 g/L的乳酸菌发酵废水（LFW）中的应用。产朊假丝酵母对乳酸的利用有助于缓解反馈抑制，从而促进凝结芽孢杆菌的生长。凝结芽孢杆菌和产朊假丝酵母对TOC的去除率分别仅为9.1%和22.7%，通过共培养提高到了49.0%。凝结芽孢杆菌和产朊假丝酵母对TN的去除率分别仅为6.3%和12.5%，通过共培养也提高到了44.6%。共培养实现了凝结芽孢杆菌的高生长以及对LFW中TOC和TN的高效去除，这在以前未见报道，并且在利用LFW资源生产益生菌方面非常重要。
