Biogas bacteria

Biogas is produced by the bacteria in the form of small bubbles these float upward through the sludge bed/blanket, providing a good mixing action. When the biogas reaches the top of the reactor, it is collected and used as a fuel. 

Biogas is composed primarily of methane (GH ) and carbon dioxide. Biogas is a by-product from anaerobic bacteria breaking down organic material. Large amounts of biogas can be released from areas such as... 

This process is an extension of the anaerobic treatment of waste diseussed in Chapter 2, and is also similar to the natural process operating in landfill sites, which evolves methane. By treatment of biomass with bacteria in the absence of air a gas rich in methane can be produced a typical digester may produce over 300 m of gas containing over 50% methane per tonne of dry biomass. The economics of biogas generation for use as a fuel are currently unfavourable. The plants that do exist have been built because of the need to treat waste such as sewage sludge. 

Anaerobic decolorization of azo dyes was started back in the 1970s. Reticulated sintered glass was used as immobilization of anaerobic bacteria for the decolorization of wastewater and transformation of the azo dye to degradable products [58], Full decolorization was achieved in less than 4 h HRT, and in addition to it, methane as biogas was also produced. 

The same types of anaerobic bacteria that produced natural gas also produce methane today. Anaerobic bacteria are some of the oldest forms of life on earth. They evolved before the photosynthesis of green plants released large qnantities of oxygen into the atmosphere. Anaerobic bacteria break down or digest organic material in the absence of oxygen and produce biogas as a waste product. 

Biogas or synthetic natural gas production can be accomplished by utilizing the process of anaerobic digestion to convert biomass into methane. This multistage process of anaerobic decomposition involves hydrolysis of complex organic compounds by multiple bacterial species. The bacteria are grouped into the following classes ... 

In the absence of oxygen, in a closed reactor, anaerobic bacteria ferment organic matter into methane and carbon dioxide, a mixture named biogas. Biogas is produced through the activity of common methane bacteria that cause anaerobic degradation over a broad temperature range from 10°C to over 100°C. 

Biogas is the general term for gases produced by the fermentation of manure and plant material under anaerobic conditions. When plant material (manure, straw, vegetables) decays in the absence of air, bacteria produce biogas. Biogas is a mixture of 60% methane and carbon dioxide.
