2-methyl-1,8-octanediamine (MODA) was not biodegraded under the conditions of the present study.
A study was performed in order to determine the extent to which the
substance 2-methyl-1,8-octanediamine (MODA) is biodegraded. The study
was conducted to GLP and in accordance with the “Biodegradation Study of
Chemicals” specified in "About Test Methods for New Chemical Substances"
(Kanpogyo Notification No. 5, Yakuhatsu Notification No. 615, and 49
Kikyoku Notification No. 392 dated July 13, 1974) and “Ready
Biodegradability: 301C, Modified MITI Test (I)” specified in the “OECD
Guidelines for Testing of Chemicals (dated July 17, 1992). Active sludge
samples were obtained from 10 Japanese sites, and after preparation were
inoculated to the prepared test solutions so that the concentration of
suspended substances was 30 mg/L at a temperature of 25±1°C over a
period of 28 days and after treatment with a concentration of the test
substance of 100 mg/L. The results were compared against a blank and a
positive control (aniline).
