Abstract

Lactic acid plays an important role in industrial applications ranging from the food industry to life sciences. The growing demand for lactic acid creates an urgent need to find economical and sustainable substrates for lactic acid production. Agricultural waste is rich in nutrients needed for microbial growth. Fermentative production of lactic acid from non-food-competing agricultural waste could reduce the cost of lactic acid production while addressing environmental concerns. This work provided an overview of lactic acid fermentation from different agricultural wastes. Although conventional fermentation approaches have been widely applied for decades, there are ongoing efforts toward enhanced lactic acid fermentation to meet the requirements of industrial productions and applications. In addition, agricultural waste contains a large proportion of pentose sugars. Most lactic-acid-producing microorganisms cannot utilize such reducing sugars. Therefore, advanced fermentation techniques are also discussed specifically for using agricultural waste feedstocks. This review provides valuable references and technical supports for the industrialization of lactic acid production from renewable materials.

利用农业废弃物生产乳酸的先进发酵技术

乳酸在从食品工业到生命科学的工业应用中发挥着重要作用。对乳酸的需求不断增长，迫切需要找到经济和可持续的乳酸生产基质。农业废弃物富含微生物生长所需的营养物质。利用非食品竞争性农业废弃物发酵生产乳酸可以降低乳酸生产成本，同时解决环境问题。这项工作提供了一个概述乳酸发酵从不同的农业废弃物。尽管传统的发酵方法已经被广泛应用了几十年，但仍在努力提高乳酸发酵，以满足工业生产和应用的要求。此外，农业废弃物中含有大量戊糖。大多数产生乳酸的微生物不能利用这种还原糖。因此，还专门讨论了利用农业废弃物原料的先进发酵技术。这篇综述为可再生材料生产乳酸的工业化提供了宝贵的参考和技术支持。
