RESUMO

A selective procedure was used to isolate pectinolytic intestinal bacteria from human subjects. The three isolates with the greatest pectinolytic activity utilized pectin and a few related compounds as fermentable substrates for growth but did not utilize any other compound tested. Thus, their substrate utilization pattern was markedly different from that of previously described intestinal pectinolytic isolates. The three isolates are representatives of a nutritionally defined group of bacteria for which the term pectinophilic is proposed.
