a Data from CO2 production and cell yield by washed cells.
b Data from analysis of the decay rate of pentane extracts; specific affinities estimated from Vmax/Km for these and subsequent data.
c Data from CO2 production and cell yield in fresh sample.
d Data from headspace analysis of the rate of toluene decay.
