Study of the biodeterioration of vulcanized rubber pipe-seals exposed to inoculated tap water
article
A novel natural rubber vulcanizate has been tested for its resistance to attack by the rubber-degrading bacterium Nocardia asteroides under conditions which simulate those of pipe-seals in water-supply pipes. The vulcanizate was exposed to tap water inoculated with rubber-degrading bacteria. The growth of bacteria on the surface of the material and any resultant deterioration were monitored by scanning electron microscopy, fluorescence microscopy, transmission electron microscopy, viable counts in selective media and the determination of tensile strength. After an exposure of nearly two years the samples were found to have undergone no significant deterioration.
