Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Ready biodegradability of glycine was investigated in a MITI test using a mixture of sewage, soil and water from 10 collection sites as inoculum (Noguchi, 1993). The test was conducted according to OECD guideline 301 C. After a contact time of 14 days, glycine attained 76-82% degradation based on oxygen consumption and 96-100% degradation based on DOC removal. HPLC analysis of the substance confirmed full degradation of glycine. Hence, glycine can be determined as readily biodegradable according to the OECD criteria.
