Abstract: The invention relates to a process for the production of biogas from organic material comprising: treating said organic material with an enzyme composition comprising a phytase, preferably a phytase and a cellulase and/or hemicellulase, and digesting the enzyme treated organic material to form biogas, and further to the use of an enzyme composition comprising a phytase to increase the digestibility of proteins and polysaccharides by microbes present in a process suitable for the conversion of organic material into biogas; the use of an enzyme composition comprising a phytase to increase the availability of minerals in a process suitable for the conversion of organic material into biogas; and the use of an enzyme composition comprising a phytase to reduce precipitation of salts on hardware such as (metal) surfaces and in lines and pumps in a process suitable for the conversion of organic material into biogas.
