[Transformation of the herbicide 2,4-D in an Azotobacter culture]

Transformation of the herbicide 2,4-D[14C] was studied in the cultures of Azotobacter chroococcum, Azotobacter vinelandii and Azotobacter agile. These cultures assimilated 2,4-D and metabolized it. The products of transformation included phenol derivatives, water-soluble products, and carbon dioxide. About 15% of the herbicide taken up by the cells was bound to protein.
