Contents Notes
Nineteen new strains of bacteria capable of degrading cresol have been isolated and characterized. All are capable of simultaneous metabolism of all three isomers of cresol at concentrations of 900 ppm. Four of the most promising organisms have been subjected to physiological studies to determine optimal and extremes of sewage activity. The following can be stated: (1) Optimal pH 7.3 to 8.3, optimal temperature 35 degrees Centigrade with some activity at 45 degrees Centigrade, have ability to survive short periods of cresol starvation and upon re-exposure again metabolize cresol as may be seen in field conditions. (2) At least one strain can thrive on cresol concentration of 1450 ppm which is three times greater than any published reports. (3) All strains appear able to metabolize o-dichlorobenze, a toxic compound and a problem in treatment of industrial wastes.
