CORYNEBACTERIUM BARKERI, nov. spec.; A PECTINOLYTIC BACTERIUM EXHIBITING A BIOTIN-FOLIC ACID INTER-RELATIONSHIP

Abstract

The isolation of a pectinolytie bacterium, Corynrbacterium barkeri nov spec is described. Its morphological, cultural, physiological and nutritional adibutes are enumerated. The organism has an unusual vitamin nutrition in that i& recpiremcnf far biotin ir partly replaceable by folic acid. Calcium has been shown to'bc essential for pectin decdrnposition. The name Coryxbndeiiem borkeri, no spec., in hbnour bf Dr. H. A. Barker, has been proposed for this bacterium.
