Lactic acid fermentation of food waste as storage method prior to biohydrogen production: Effect of storage temperature on biohydrogen potential and microbial communities

This study aims to investigate the impact of utilizing lactic acid fermentation (LAF) as storage method of food waste (FW) prior to dark fermentation (DF). LAF of FW was carried out in batches at six temperatures (4 �C, 10 �C, 23 �C, 35 �C, 45 �C, and 55 �C) for 15 days followed by biological hydrog...

LAF of FW was carried out in batches at six temperatures (4 �C, 10 �C, 23 �C, 35 �C, 45 �C, and 55 �C) for 15 days followed by biological hydrogen potential (BHP) tests. Different storage temperatures resulted in different metabolites distribution, with either lactate or ethanol being dominant (159.2 � 20.6 mM and 234.4 � 38.2 mM respectively), but no negative impact on BHP (averaging at 94.6 � 25.1 mL/gVS).
