Question : How microbes are used in Gobar gas production ? |
|
Answer» Solution :Biogas is a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen Biogas can be produced from raw materials such as agricultural wastes, manure municipal wastes , plant material sewage food waste , etc Biogas is produced under anaerobic condition when the organic fertilizer Biogas PRIMARILY consists of methane (63 PERCENT), along with `CO_(2)` and hydrogen Methane producing bacteria are called methanogens and one such common bacterium is Methanobacterium Biogas is devoid of smell and burns with a blue flame without smoke . The Methanogens are also present in anaerobic sludge and rumen of cattle In rumen , these bacteria help in the breakdown of cellulose . Theexcreta of cattle called dung is commonly called Gobar gas is generated by the anaerobic decomposition of cattle is commonly called Gobar . Gobar gas is generated by the anaerobic decomposition of cattle dung . It consists if methane `CO_(2)` with some hydrogen nitrogen and other gases in trace amounts. In a biogas plant anaerobic digestion is carried out in an air TIGHT cylindrical tank known as digester . It is made up of concrete bricksand cement or steel Bio - wastes are collected and slurry of dung is fed into this digester . It has a side OPENING into which organic materials for digestion are incorporated formicrobial activity . Anaerobic digestion is accomplished in three stages : solubilisation acidogenesis and methanogenisis . The outlet and is used as fertilizer . Biogasis used for cooking and lighting . the TECHNOLOGY of biogas production was developed in India mainly due to the efforts of Indian Agricultural Research Institute (IARI) and Khadi and Village Industries Commission (KVIC). |
