Optimizing anaerobic digestion: Benefits of mild temperature transition from thermophilic to mesophilic conditions

Environmental Science and Ecotechnology
Anaerobic digestion (AD) plays a significant role in renewable energy recovery. Upgrading AD from thermophilic (50–57 °C) to mesophilic (30–38 °C) conditions to enhance process stability and reduce energy input remains challenging due to the high ...

Expanding the potential soil carbon sink: unraveling carbon sequestration accessory genes in vermicompost phages

Applied and Environmental Microbiology
The compost microbiome is important in regulating soil carbon sequestration. However, there is limited information concerning phage communities and phage-encoded auxiliary metabolic genes (AMGs) in compost-applied soils. We combined metagenomics and meta-
