Microbial growth on 2-bromobutane

A member of the genus Arthrobacter was isolated which grew at the expense of 2-bromobutane as sole source of carbon and energy. Evidence is presented which suggests that the initial conversion of 2-bromobutane to 2-butanol is a spontaneous chemical hydrolysis and not mediated by the organism. Further evidence from oxygen consumption experiments indicates that 2-bromobutane is oxidized through 2-butanol, methyl ethyl ketone, ethyl acetate to acetate and ethanol. Results of experiments with cells grown on pathway intermediates reveal that the enzymes necessary for the oxidation of 2-butanol, methyl ethyl ketone, ethyl acetate, ethanol and acetaldehyde are not coordinately, but individually induced by their respective substrates.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/41779/1/10482_2004_Article_BF00421980.pd
