Abstract

Azotobacter chroococcum isolated from forest soils containing decaying wood efficiently cleaved 2,4‐dichlorophenoxyacetic acid. The cleavage was profoundly influenced by cell concentration, moisture content of the soil and temperature at which the soil was incubated. Increase in cell concentration increased 2,4‐D degradation. At 30°C, 58% of the 2,4‐D was degraded and 50% moisture content favoured maximum degradation of 2,4‐D.
