During these processes especially for the former one, play a key role some kind of specialized microorganisms which can produce a mixture of gases (Biogas composed of 65% methane and 35% carbon dioxide) and a mixture of liquid (which carries a high value of mineral nutrient elements like nitrogen, phosphorus, especially used as fertilizer additive, etc. References: [1] S.
