Anaerobic cometabolism of fruit and vegetable wastes using mammalian fecal inoculums: Fast assessment of biomethane production

Performance of thermophilic anaerobic digesters using inoculum mixes with enhanced methanogenic diversity

“…Similarly, inocula containing both hydrogenotrophic orders ( Methanobacteriales and Methanomicrobiales ) were included in the seeding mixes. In addition to enriching the methanogenic component, combining several seeding sources increases the chances of an overall diverse microbial community that offers the advantage of better and faster degradation of organic compounds due to syntrophic interactions where the waste of one species is needed by other species …”

“…In addition to enriching the methanogenic component, combining several seeding sources increases the chances of an overall diverse microbial community that offers the advantage of better and faster degradation of organic compounds due to syntrophic interactions where the waste of one species is needed by other species. 9 Five types of seeding sources were tested using QPCR: thermophilic digestate, cattle manure, WAS, compost and leachate. The digestate and manure exhibited a very close methanogenic composition.…”

“…Alternatively, several types of manure, e.g. horse, dog and sheep feces, were mixed to enhance the anaerobic ‘co‐metabolism’ of fruit and vegetable waste …”

“…horse, dog and sheep feces, were mixed to enhance the anaerobic 'co-metabolism' of fruit and vegetable waste. 9 Other sources, less studied than animal manure, that have the potential to enrich the initial seed include municipal waste compost and landfill leachate. In fact, municipal waste compost can host thermophilic methanogens in anoxic niches, at a level of ∼ 2 × 10 7 to 10 9 g −1 dry weight.…”

Use of Waste to Obtain Energy in Latin America: A Systematic Review

“…Obtaining biogas from waste Evaluates and verifies the implementation of an electromagnetic field in anaerobic digestion for the conversion of organic waste into biogas (de Souza Matos Biogas production from fruit and vegetable waste (Islas-Espinoza et al, 2017).…”
