Abstract

Lactic acid is a versatile building block that can be produced via microbial fermentation. Owing to the high optical purity, approximately 90 % of lactic acid is produced by microbes. Recently, the biosynthesis of lactic acid from lignocellulose has concerned much attentions. However, the cost-effective process faces several obstacles because of the complex structure of lignocellulose. This review will comprehensively summarize the state-of-the-art lactic acid production from lignocellulose, including the commonly used lactate-producing microorganisms, the co-utilization of glucose and xylose for the lactic acid production, as well as the lactic acid production from lignocellulose hydrolysate. Furthermore, the strategies regarding the lignocellulosic lactic acid production via consolidated bioprocessing will be also discussed, which can greatly reduce the complexity of the fermentation process.

利用木质纤维素生产乳酸的进展与前景。

乳酸是一种可通过微生物发酵生产的多功能建筑材料。由于光学纯度高，大约 90% 的乳酸由微生物生产。最近，从木质纤维素中生物合成乳酸备受关注。然而，由于木质纤维素结构复杂，这一经济有效的工艺面临着一些障碍。本综述将全面总结从木质纤维素中生产乳酸的最新技术，包括常用的乳酸生产微生物、葡萄糖和木糖共同用于乳酸生产以及从木质纤维素水解物中生产乳酸。此外，还将讨论通过综合生物工艺生产木质纤维素乳酸的策略，这可以大大降低发酵过程的复杂性。

期刊介绍： Enzyme and Microbial Technology is an international, peer-reviewed journal publishing original research and reviews, of biotechnological significance and novelty, on basic and applied aspects of the science and technology of processes involving the use of enzymes, micro-organisms, animal cells and plant cells. We especially encourage submissions on: Biocatalysis and the use of Directed Evolution in Synthetic Biology and Biotechnology Biotechnological Production of New Bioactive Molecules, Biomaterials, Biopharmaceuticals, and Biofuels New Imaging Techniques and Biosensors, especially as applicable to Healthcare and Systems Biology New Biotechnological Approaches in Genomics, Proteomics and Metabolomics Metabolic Engineering, Biomolecular Engineering and Nanobiotechnology Manuscripts which report isolation, purification, immobilization or utilization of organisms or enzymes which are already well-described in the literature are not suitable for publication in EMT, unless their primary purpose is to report significant new findings or approaches which are of broad biotechnological importance. Similarly, manuscripts which report optimization studies on well-established processes are inappropriate. EMT does not accept papers dealing with mathematical modeling unless they report significant, new experimental data.
