Bacterial degradation of ammonium lignosulfonate.
Bacterial strains were selected for their capacity to assimilate and to transform ammonium-lignosulfonate. Modification of the methyl content and of low molecular weight alkyl functions were demonstrated by gas-chromatography and HLPC analysis. Most of these strains completely degraded simple phenolic compounds related to lignosulfonate without inhibition by the carbohydrates present in the liquor. Further investigation suggested that the enzymes involved in the fission of the aromatic nuclei were constitutive in the strains tested.
