Bacteroides thetaiotaomicron - 690418, 690969, 692529 Bacteroides thetaiotaomicron isoenzymes I and II 34087 Paenarthrobacter aurescens - 690418 Pedobacter heparinus - 34081, 34082, 34086, 665449 Pedobacter heparinus isoform chondroitinase AC, upon growth on peptone with or without the inducer chondroitin sulfate, high specific activities for chondroitinases during the initial 6 h, which decreased thereafter. In contrast, in tryptic soy broth, high specific activities were obtained after 24 h growth in the presence of the inducer, generating large amounts of chondroitinase-rich extracts 34089 Proteus vulgaris - 34081, 34085, 663950, 663965, 665450, 705923, 705924, 706560, 714652 Proteus vulgaris growth on medium containing chondroitin sulfate C 34086, 665449 Proteus vulgaris induction of enzyme by addition of chondroitin sulfate C to growth medium 34084 Proteus vulgaris NCTC 4636 662099 Proteus vulgaris NCTC 4636, induced by chondroitin sulfate, isoenzyme ChS ABC lyase II 662099
