Description of key information

All enzyme classes are readily biodegradable. Degradation products are primarily peptides and amino acids, then carbon dioxide and water which cause no harm to nature [1]. OECD ready biodegradability tests have been conducted on lipases, cellulases and amylase with results (92 to 99% DOC removal) that surpass the OECD threshold limit of 70% DOC removal [2].
