Studies of microbial diversity during dark fermentation of food waste

Deciphering the microbial composition is one of the most important steps in dark fermentation studies in order to optimize H2 production. In particular, changes in microbial composition after inoculum pre-treatment in comparison with the untreated inoculum reveals the efficiency of the process. Changes in microbial community composition were studied after inoculum pre-treatment with waste frying oil. Moreover, microbial dynamics were followed after dark fermentation of food waste using pre-treated inoculum.
