During synthrophic growth of Hydrogenophaga palleronii (strain S1) and Agrobacterium radiobacter (strain S2) with 4-aminobenzene sulfonate (4ABS) only strain S1 desaminates 4ABS by regioselective 3,4-dioxygenation. The major part of the metabolite catechol-4-sulfonate (4CS) is excreted and further m

✦ Synopsis
Growth of a mixed culture, Pseudomonas palleronii and Agrobacterium radiobacter using the toxic chemical " 4-aminobenzenesulfonic acid " was followed by: the measurement of the total cell density by using celi counter and the plate count procedure for enumerating each strain according to the different morphology. The results from these two procedures deviated considerably due to the inability to form colonies on solid agar media.

A mixed culture of Bacillus sp. K1 and Sphingomonas paucimobilis EPA 505 was exposed to chromate and naphthalene. Batch experiments showed that chromate was reduced and naphthalene was degraded by the mixed culture. Chromate reduction occurred initially at a high rate followed by a decrease in rate
