Kh. Oh et Ms. Cha, DEGRADATION OF DIMETHYLAMINE SALT OF 2,4-DICHLOROPHENOXYACETATE BY A MIXED BACTERIAL CULTURE IN STIRRED-TANK REACTORS, Biotechnology letters, 18(9), 1996, pp. 1035-1040
An aerated microbiological process was tested in 1.5-1 stirred tank re
actors for the treatment of dimethylamine salt of 2,4-dichlorophenoxya
cetate (2,4-D). A mixed culture was used with the concentration range
of 54 to 216 mg 2,4-D/l. The highest concentration was completely depl
eted within 6 to 8 days of contact time. 2,4-Dichlorophenol, the first
intermediate of the degradative pathway, accumulated transiently in t
he growth medium.
