Abstract

Abstract

The effects of hydrochar and pyrochar prepared by food waste on the production of caproate from food waste fermentation were investigated. The physicochemical properties of the biochar and microbial community were analyzed. The results showed that the maximum production of caproate was only 1.65 g COD/L in the blank. The addition of 5 g/L hydrochar and pyrochar both promoted the production of caproate with the maximum production at 3.64 g COD/L and 24.24 g COD/L, which were 2.2 times and 14.7 times that in the blank respectively. While excess hydrochar and pyrochar (10 g/L and 20 g/L) inhibited the production of caproate. The comparative analysis of the physicochemical properties of the biochar showed that the pyrochar could promote direct interspecies electron transferring, and pyrochar with a larger specific surface area could provide more attachment sites for the functional microbes for caproate production and enrich its abundance, promoting the conversion of ethanol and butyrate into caproate. Microbial community analysis showed that the relative abundance of functional microbes for caproate production including Clostridium_sensu_stricto_12, Caproiciproducens and Clostridium_sensu_stricto_11 in the 5 g/L pyrochar was 35.6%, 2.0% and 1.7%, respectively.
