OECD SIDS
4-METHYLPENTAN-2-OL
3. ENVIRONMENTAL FATE AND PATHWAYS ID: 108112
DATE: 4.07.2006
Type : aerobic
Inoculum : other: activated sludge from synthetic waste
Method : Alcohol added to flask at 16 mg/l, no information on
inoculum concentration, alcohol degradation time course
measured by GC.
Remark : This study investigated the relationship of biodegradation
rate constants for aliphatic alcohols, including
2-methyl-4-pentanol, to their octanol water partition
coefficients. The biodegradation rate constant for
2-methyl-4-pentanol was 0.0477.
Reliability : (4) not assignable
