摘要：The potential for production of chemicals from microalgal biomass has been considered as an alternative route for CO₂ mitigation and establishment of biorefineries. This study presents the development of consolidated bioprocessing for succinate production from microalgal biomass using engineered Corynebacterium glutamicum . Starch-degrading and succinate-producing C. glutamicum strains produced succinate (0.16 g succinate/g total carbon source) from a mixture of starch and glucose as a model microalgal biomass. Subsequently, the engineered C. glutamicum strains were able to produce succinate (0.28 g succinate/g of total sugars including starch) from pretreated microalgal biomass of CO₂-grown Chlamydomonas reinhardtii . For the first time, this work shows succinate production from CO₂ via sequential fermentations of CO₂-grown microalgae and engineered C. glutamicum . Therefore, consolidated bioprocessing based on microalgal biomass could be useful to promote variety of biorefineries.
