Description 438-442
Bacterial
degradation of phenol (100 to 800 ppm) was studied. It was observed that
bacterial diversity and the rate of phenol biodegradation were influenced by
the phenol concentrations in the medium. The rate of biodegradation was reduced
at higher concentrations of phenoli and Pseudomonas spp and Vibrio
spp were mainly involved in the process. The distribution of bacterial
genera in the medium was dependent on the compound and its concentration. Pseudomonas
and Vibrio were present in all concentrations of phenol, o-cresol
and orcinol. Whereas, Bacillus and Alcaligenes could tolerate
only up to 200 ppm of these compounds in the medium.  Flavobacterium was absent in o-cresol,
while it could tolerate 500 ppm of orcinol and 200 ppm of phenol. Cytophaga tolerated
300 ppm of orcinol, and 100 ppm of phenol and o-cresol.

From the
present study, it is concluded that in case of an accidental spill of these
phenolic compounds many naturally present bacteria could be of great help in
their biodegradation and purification of the system thereafter.
