The recovery of biomass energy from food waste through anaerobic digestion as an alternative to fossil is great significance for the development environmental sustainability and circular economy. However, a substantial number additives (e.g., salt, allicin, capsaicin, allyl isothiocyanate, monosodium glutamate, nonnutritive sweeteners) are present in waste, their interactions with might affect recovery, which typically overlooked. This work describes current understanding occurrence fate waste. biotransformation pathways during well discussed. In addition, important discoveries effects underlying mechanisms on reviewed. results showed that most had negative by deactivating functional enzymes, thus inhibiting methane production. By reviewing response microbial communities additives, we can further improve our impact digestion.

Magnetite-loaded biochar generated by gasification serves as a potential additive to facilitate electron transfer and boost methane production. In this study, the focus was placed on mechanism of magnetite-loaded biochar-enhanced methanogens with live bacteria in real habitats, connection between microorganisms methanogenic pathway revealed. produced at FeCl3-to-woodchip ratio (w/w) 15/100 presented maximal production, where daily yield improved 157% compared control. Magnetite accelerated consumption short-chain fatty acids through dissimilatory iron reduction, it converted into siderite goethite after anaerobic digestion. The cycle coupling organic removal enhanced efficiency further transmitted electrons promote methanogenesis. As indicated from results, high DNA (Atelge, M. R.; Atabani, A. E.; Banu, J.
