Data underlying the publication: nZVI impacts substrate conversion and microbiome composition in lactate-based chain elongation from D- and L-lactate substrates

Medium-chain carboxylates (MCC) derived from biomass biorefining are attractive biochemicals to uncouple the production of a wide array of products from the use of non-renewable sources. Biological conversion of biomass-derived lactate during secondary fermentation can be steered to produce a variety of MCC through chain elongation. We explored the effects of zero-valent iron nanoparticles (nZVI) and lactate enantiomers on substrate consumption, product formation and microbiome composition in batch lactate-based chain elongation.

源自生物质生物炼制的中链羧酸盐（Medium-chain carboxylates, MCC）是一类极具吸引力的生物基化学品，可实现各类产品生产与不可再生资源使用的解耦。在二次发酵过程中，对生物质来源乳酸的生物转化进行调控，可通过链延长途径生成多种中链羧酸盐。本研究探究了零价铁纳米颗粒（zero-valent iron nanoparticles, nZVI）与乳酸对映体对基于乳酸的分批式链延长体系中底物消耗、产物生成及微生物组组成的影响。
