Spirulina is the major source of biogas production.
Spirulina is an organism that grows in both fresh and salt water. It is a type of bacteria called cyanobacterium, which is often referred to as blue-green algae used as a source of valuable food specifically used for proteins. It is not used in the production of biogas. The production of biogas requires microbes which can undergo decomposition where they breakdown organic matter in the absence of oxygen and produce biogases like methane.
