Enzymes for Bio-Gas Generation
USE OF ANCHORED ENZYMES FOR BIO-GAS GENERATION AND PRODUCTION OF NATURAL GAS: An Indian company is offering this technology. Anchored methanogenic enzymes are prepared from cultured methane bacteria. These enzymes are superior to endogenous methane bacteria in that, they by-pass the constraints posed by the miss-match between Solids Retention Time (SRT) and Hydraulic Retention Time (HRT), thus enhancing the bio-gas production rate by as much as 10 times. The use of these enzymes also improves the CH4: CO2 ratio, from the usual 60:40 to 75:25. The bio gas thus produced, yields natural gas, which is essentially methane, by removing the carbon dioxide (CO2) using any of the following techniques : (i)Absorbing CO2 in an alkaline absorbent; (ii) Dissolving the CO2 under pressure in water; (iii) Freezing and separating the CO2 from CH4; (iv) Diffusion through a porous tube. Apart from the usual source of bio-gas, i.e., cow-dung, Municipal Solid Waste (MSW) and sewerage containing cellulose bio-degradable components, can also be used as the feed stock. Such a procedure will fully meet the entire fuel needs of the country - for power generation, running of vehicles, etc. greatly reducing environmental pollution. Use of MSW, duly sorted and components separated, will also yield many Value Added Products (VAP), with significant commercialization potential. The methane can be used as feed-stock for many industrial chemicals, as also for the production of hydrogen (H2), to be used in fuel cells - a multi-million dollar enterprise in the USA.
