Continuous Biohydrogen Production from Sugarcane Molasses

The potentials of using biodigestion as a core processing step in sugarcane biorefineries opens up a wide range of biotechnological possibilities, in which sugar-rich materials may be fermented without adding acquisition costs. This study aimed to the optimization of the continuous long-term (630 d) thermophilic bioH2 production from molasses, defining adequate hydraulic retention time (HRT) levels. And the study of the compartmentalized assessment was used to unravel the dynamics of substrate conversion, cell retention patterns and the microbial characterization in different zones of a thermophilic molasses-fed fixed-film reactor at low organic loading rate.
