Background: The thermophilic, anaerobic bacterium, Clostridium thermocellum is a model organism for consolidated processing due to its efficient fermentation of cellulose. Constituents of dilute acid pretreatment hydrolysate are known to inhibit C. thermocellum and other microorganisms. To evaluate the biological impact of this type of hydrolysate, a transcriptomic analysis of growth in hydrolysate-containing medium was conducted on 17.5%?v/v Populus hydrolysate-tolerant mutant (PM) and wild type (WT) strains of C. thermocellum.ResultsIn two levels of Populus hydrolysate medium (0% and 10%?v/v), the PM showed both gene specific increases and decreases of gene expression compared to the wild-type strain. The PM had increased …
