Sep 22, 2018 · The most effective proportion is with the ratio of 10:80:10 of water hyacinth: cow dung: sawdust and followed by 20:70:10 water hyacinth: cow dung: saw dust. The calorific value gets reduced to 3997.5 and 3875, respectively, for two proportions, respectively.

Oct 10, 2023 · Recently, the industrial focus has shifted to renewable raw materials due to the exhaustion and rising pressures about environmental and political issues. Lignocellulosic biowaste can be derived from a range of sources, such as animal manure, forestry waste, and agricultural waste, and it can be transformed into lactic acid through a biochemical process. There are 942.63 million cattle in the

Dec 22, 2012 · Cow dung, a cheap and easily available source of energy, was used as the substrate for the production of alkaline protease by solid-state fermentation using the Bacillus subtilis strain VV. In order to achieve the maximum yield of this enzyme, the following optimum process parameters are needed: fermentation period (72 h), pH (10.0), moisture content (140%), inoculum (25%), temperature (30

The potentials of biogas yield from cow dung were analyzed using standard microbiological . The results revealed that optimum biogas yield from cow dung without starter culture was 345mls, 640mls and 720mls and in the treatment with starter culture was 490mls, 640mls and 830mls respectively in 1kg, 2kg and 3kg weights within 15 days.

Nov 1, 2022 · Many countries are producing biogas from cow dung and agricultural and industrial wastes; India, Taiwan, USA, England, grace and Germany are producing biogas through anaerobic digestion process (Lovrak et al., 2022). During the anaerobic digestion process, agro-industrial waste is converted into biogas or methane with the optimized production process parameters, carbon to nitrogen ratio

Jun 1, 2016 · Possible applications of cow dung microorganisms in pharmaceutical industry has been indicated by Teo and Teoh and it was shown that isolate K4 possessed antibacterial activity against E. coli. Research has also been conducted on water, ethanol and n-Hexane extract of whole cow dung against Candida, E. coli, Pseudomonas and

Nov 17, 2023 · Biogas is a mixture of gases generated by decaying biodegradable material without the presence of oxygen. Its main contents are 50–70% of methane (CH4) by volume, 30–50% of carbon dioxide (CO2

Jan 10, 2015 · The result obtained from the biogas production showed that the co-digestion of cow dung and food waste produced the highest biogas of 164.8%, followed by the co-digestion of the three waste (cow

Jul 12, 2023 · Cow dung contains high concentrations of organic matter, which can be used for methane production by anaerobic digestion. However, the refractory lignocellulose in cow dung often hiders methane production through anaerobic digestion. Ultrasonic pretreatment is an efficient method to enhance lignocellulose degradation and methane production, but the mechanism is not well studied. In this work

E3S Web of Conferences, 2020. This paper aims at finding the effect of co-digestion of cow dung and food waste on total biogas yield. Biogas production was improved through co-digestion of cow dung and food waste (FW) containing a small fraction of inoculum under mesophilic temperature (37ºC) over a retention time of 24 days.
