摘要 |
The present invention relates to biogas production processes with enzymatic pre-treatment, said processes comprising the steps of providing a slurry comprising a lignocellulose- and pectin-containing material, water and two or more enzyme treatments; allowing the two or more enzyme-treatment steps to degrade the lignocellulose- and pectin-containing material, and adding the degraded material to a biogas digester tank at a suitable rate and ratio to effectively convert the material to biogas in the digester. |
