生物质制备乳酸研究进展

Research progress on lactic acid preparation with biomass

在众多的替代和新生资源之中,生物质资源由于其低成本、广泛易获取性和可再生性等特点而越来越受到重视,可作为生产能源、饲料和其他高附加值化学品的重要原料,成为了人类将来发展的替代资源之一。该文对以可再生生物质为原料通过发酵法生产具有广泛应用乳酸的研究进展进行了概述,并就现阶段在乳酸生产菌株、可再生生物质的种类及其前处理的方法、乳酸生产过程中营养源及乳酸的新型应用这几个方面进行了阐述。最后,对乳酸生产进行了未来工艺优化,下游产物的发展方向进行了展望。

Development and utilization of new resources has become the global problem. Compared with other energy substitute and new resources, biomass resources have advantages of low cost, wide available and renewable and attracted more attention. As important raw material of energy, feeds and other high-valued chemicals, biomass becomes one of alternative resources for future. The research progress on fermentation of lactic acid from biomass illustrates reviewed, mainly focused on lactic acid producing strains, types of renewable biomass, pretreatment methods, nutrients supplementation and the novel application of lactic acid. Finally, the optimization of fermentation technology and future perspectives of down-stream products are summarized.
