Biodegradation in water:
under test conditions no biodegradation observed

Additional information

The ultimate biodegradability of Glycyl (GR3400A) was assessed by measurement of generated carbon dioxide. The procedure followed was Standard 14593 of the Internal Organisation for Standardisation (ISO), which is essentially equivalent to OPPTS guideline 835.3120.

The mean inorganic carbon yield attributable to Glycyl (GR34000A) was less than 1% of the initial organic carbon loading thoughout the time course of this study. Although Glycyl (GR34000A) did not undergoe significant mineralisation under the conditions employed in this study, this is not necessarily an indication that Glycyl (GR34000A) would persist or accumulate in the environment.
