title: Resistance of Thiobacillus novellus to mitomycin C and rifampicin.
abstract: Thiobacillus novellus is highly resistant to mitomycin C and rifampicin. This resistance is not due to insusceptibility of the target molecules to the drugs, since mitomycin C cross-links the DNA and rifampicin inhibits the DNA-dependent RNA polymerase of T. novellus in vitro.
