| Abstract: | In this study, an efficient and economical method for fractionation and sequential utilization of whole components of Chinese fir sawdust (CFS) was explored. By reusing hemicellulose hydrolysate, 54 % sulfuric acid was saved during the pretreatment process. Additionally, a robust strain of Bacillus coagulans CC17B was obtained through adaptive evolution, which not only could utilize the 100 % (v/v) reused hydrolysate without detoxification but was also unaffected by carbon catabolism repression. Combined with fed-batch simultaneous saccharification and fermentation, 54.8 % of the carbohydrate of Chinese fir sawdust was finally converted to lactic acid through B. coagulans CC17B. Furthermore, 44.6 % of the lignin was recovered from the liquid fraction, showing potential for efficient conversion to bio-oil. Overall, the hydrolysate reusing process and high robust strain of B. coagulans CC17B was applied to improve the economics of CFS biorefinery, which provides a promising strategy for the complete utilization of softwood biomass. [Display omitted] • The dilute acid usage was saved 54 % through hemicellulose hydrolysate reusing. • A robust Bacillus coagulans with excellent tolerance to hemicellulose hydrolysate was obtained. • The holocellulose of softwood were converted to lactic acid through B. coagulans CC17B.
