Abstract
An organism of the genus Corynebacterium rapidly decomposes 2,4-D in pure culture in a synthetic medium. Additives to the medium do not increase the fermentation rate significantly, although certain amino acids do so when provided as sources of N. Total destruction of the molecule is indicated by recovery of 2,4-D chlorine concurrent with loss of its spectro-photometric identity. Manometric experiments tend to substantiate complete destruction, showing an R.Q. of 1.12.
