The anaerobic digestion of cow dung was investigated for 30days in a laboratory scale batch reactor. Totally nine bacterial strains were isolated from cow dung slurry. The bacterial isolates were preliminarily examined by morphological characteristics and they were further confirmed by 16S rRNA sequencing and analyzed through BLAST. Microbial dynamics showed that hydrolytic bacterial population...

Anaerobic digestion model No.1 (ADM1) was applied and expanded in this study to model and simulate anaerobic digestion (AD) of an industrial carbon capture reclaimer MEA (monoethanolamine) waste (MEAw) together with easily degradable organics. The general structure of ADM1 was not changed except for introducing state variables of MEA and complex organics (CO) in the waste and biochemical reacti...

BACKGROUND The hydrolysis of seaweed polysaccharides is the rate limiting step in anaerobic digestion (AD) of seaweeds. Seven different microbial inocula and a mixture of these (inoculum 8) were therefore compared in triplicate, each grown over four weeks in static culture for the ability to degrade Laminaria hyperborea seaweed and produce methane through AD. RESULTS All the inocula could deg...

Degrading antibiotics discharged in the livestock manure in a well-controlled bioprocess contributes to a more sustainable and environment-friendly livestock breeding. Although most antibiotics remain stable during manure storage, anaerobic digestion can degrade and remove them to various extents depending on the concentration and class of antibiotic, bioreactor operating conditions, type of fe...

Tobacco is widely planted across the world especially in China, which means that a large amount of tobacco waste needs to be treated. This study investigated the biogas fermentation of tobacco stalks co-digested with different biomass feedstocks and the inactivation of Tobacco mosaic virus (TMV), Cucumber mosaic virus (CMV) by anaerobic digestion. Results showed that the maximum methane yield o...

This study explored the effect of eight antimicrobials on efficiency biogas production in anaerobic digestion (AD) process cattle manure. The microbiome involved AD, presence and number genes mcrA, MSC MST specific for Archaea, antibiotic resistance (ARGs) concentration digestate (D) were examined. Supplementation antibiotics to substrate significantly lowered production. Amoxicillin caused a 7...

Abstract Basic sanitation is still lacking in many developing countries, resulting significant environmental health risks. The efficient disposal of food waste with potential resource recovery has recently gained much attention. Food considered to be a favourable substrate for the anaerobic digestion (AD) because it easy biodegradability, rich nutrient availability, and high water content. Wast...

Anaerobic digestion (AD) is the strategy of producing environmentally sustainable bioenergy from waste-activated sludge (WAS), but its efficiency was hindered by low biodegradability. Hence, usage nanomaterials found to be essential in enhancing degradability due nanostructure with specific physiochemical properties. The application thoroughly reviewed. This review focused on impact such as met...
