酒曲菌属发酵可再生材料生产乳酸的最新研究进展

Advances in Lactic Acid Production from Renewable Materials by Rhizopus Fungi

乳酸对于许多生物可降解以及生物兼容的聚乳酸聚合物的生产有很大作用,乳酸可以从大量可再生材料中通过酒曲菌属发酵制得,较之细菌来讲,酒曲菌属具有许多优势,包括淀粉分解特性、较低的营养需求量、以及富含价值的发酵副产物——真菌生物量,综述酒曲菌属发酵生产乳酸的过程管理、代谢机制以及分子生物学的最新研究进展。

Lactic acid is valuable due to wide its potentialfor the production of biodegradable and biocompatible polylactate polymers. Lactic acid can be produced from renewable materials using various fungal species of the Rhizopus genus, which have advantages compared to the bacteria, including their amylolytic characteristics, low nutrient requirements and valuable fermentation by-product-fungal biomass. This paper reviews recent research in process engineering, metabolic and enzymetic mechanisms, and molecular biotechnology associated with lactic acid production by Rhizopus fungi to get a better understanding of biochemical activities.
