Mixed culture biotechnology (MCB) could become an attractive addition or alternative to traditional pure culture based biotechnology for the production of chemicals and/or bioenergy. On the basis of ecological selection principles, MCB-based processes can be established that generate a narrow product spectrum from a mixed substrate. Three example processes are briefly discussed in this paper: anaerobic digestion aimed at the production of methane-containing biogas, mixed culture fermentation for the production of solvents or biohydrogen, and a two-step process for the production of polyhydroxyalkanoates. These examples give an idea of the potential contribution of mixed culture biotechnology to sustainable production of bioenergy from waste.
混合培养生物技术（MCB）可能成为传统的基于纯培养的生物技术在化学品和/或生物能源生产方面有吸引力的补充或替代方法。基于生态选择原则，可以建立基于MCB的工艺，从混合底物中产生狭窄的产品谱。本文简要讨论了三个示例工艺：旨在生产含甲烷沼气的厌氧消化、用于生产溶剂或生物氢的混合培养发酵，以及生产聚羟基脂肪酸酯的两步法。这些示例让我们了解了混合培养生物技术对可持续利用废物生产生物能源的潜在贡献。
