title: Small pectinolytic spirochetes from the rumen.
abstract: Two strains of small spirochetes utilizing pectin as sole source of energy for growth were isolated from the rumen of cattle and partially characterized. The pectinolytic enzyme produced by one of the organisms was classified as a poly-1,4-alpha-D-galacturonide lyase (EC 4.2.2.2). A pectinesterase (EC 3.1.1.11) was also produced.
