At psychrophilic temperatures (<20 °C), anaerobic digestion produces less methane (CH4). For (PAD) to be successful, investigation of cold-adapted microbial consortia involved in production is critical. This study aimed investigate the community driving enhanced from cold-adaptation process and bioaugmentation PAD with inoculum (BI). Microbial cattle manure (CM) food waste (FW) were adapted applied during batch CM FW bioaugment at 15 °C. Cold adaptation BI resulted cumulative specific yields 0.874 ± 0.231 0.552 0.089 L CH4 g−1 volatile solids, respectively, after 14 weeks, while absence (control) led acidification no PAD. Following 16S rRNA V4–V5 amplicon sequencing metagenomic analyses, Methanosarcina was revealed as a key driver methanogenesis cold bioaugmentation. Furthermore, based on predictive functional metabolic analysis communities, possible synergies proposed terms substrate utilization by dominant groups. instance, production, Bacteroides Methanobrevibacter possibly syntrophic relationship, which promoted Methanosarcina. These findings provide insight into prospective that can harnessed and/or regulated for improvement

Aquaponics integrates aquaculture and hydroponics, promoting circularity through the recirculation of water nutrients. However, waste management remains a challenge. This study aimed to evaluate anaerobic digestion (AD) aquaponic effluent (AE) combined with cattle manure (CM) for biogas production. An Indian model biodigester was fed AE, CM 1:1, 1:3, 3:1 W (Water):CM, under mono-digestion (MoAD) AE:CM co-digestion (CoAD) conditions. The chemical characteristics substrates digestates were assessed, as well potential production over 19 weeks. Overall, CoAD provided better results regarding characterization at Notably, 1:3 ratio resulted in most promising outcomes among tested demonstrated higher efficiency, initiating by third week reaching highest accumulated volume. It is probable that AE increased dissolved organic load, optimizing conversion matter eliminating need additional process. Thus, emerged alternative valorization aquaponics, contributing renewable energy generation, agricultural sustainability, promotion circular economy.
