✦ Synopsis

Mycobacterium aurum L1 and Xanthobacter autotrophicus G J10 were characterized with respect to their potential use in the biological treatment of waste gases containing vinyl chloride (VC) and 1,2-dichloroethane (DE). VC at a concentration of 125 g m -3 in the gas phase was not toxic but DE at 22 g m -3 already resulted in a decreased growth rate. Kinetic properties of washed cells were determined and chemostat cultures were run to optimize the medium for VC removal. Using a mixed culture of the two strains, simultaneous removal and mineralization of VC and DE was demonstrated. The affinity constants of growing cells found for the two substrates are, however, significantly higher than the maximal allowable concentrations of VC and DE in waste gases.
