Abstract The present study aimed to evaluate the hydrogen production of a microbial consortium using different concentrations of sugarcane vinasse (2–12 g COD L −1 ) at 37 °C and 55 °C. In mesophilic tests, the increase in vinasse concentration did not significantly impact the hydrogen yield (HY) (from 1.72 to 2.23 mmol H 2  g −1 COD influent ) but had a positive effect on the hydrogen production potential ( P ) and hydrogen production rate ( R m ). On the other hand, the increase in the… Expand
