Abstract

An extracellular polysaccharide was isolated from the culture medium of a virulent strain (U-7) of Pseudomonas solanacearum. The polysaccharide caused tomato cuttings to wilt. It seemed to be composed mainly of N-acetylgalactosamine together with small amounts of rhamnose, glucose, and protein. This is, to our knowledge, the first example of homo-N-acetylgalactosaminoglycan in nature.
