Biobutanol production from sulfuric acid ‐pretreated red algal biomass by a newly isolated Clostridium sp. strain WK

In this study, a diluted sulfuric acid pretreatment method was established for biobutanol from red algal biomassGelidium amansii using a newly isolatedClostridium sp. strain WK. Under the optimal condition of 2% sulfuric acid treated in 20  Min at 131 °C, the maximal hydrolysis percentage of biomass can reach up to 80.95%, and the biobutanol production was obtained to be 3.46 g/L with a yield of 0.20 g/g after the fermentation of biomass hydrolysate. This result demonstrated a 12.5‐fold enhancement of conversion efficiency comp ared with the untreated control, which provides a new and efficient way to develop the biobutanol industry by utilizing the abundant, low cost, and carbohydrate‐rich algal biomass.
