Some Characteristics of Pectolytic Bacteria Associated with Potato in Tasmania

Gram-negative pectolytic bacteria, predominantly green fluorescent pseudomonads, were obtained from approximately 13% of apparently sound selections of seed tubers in the Tasmanian Certified Seed Potato Scheme. Pseudomonads were also associated with tuber soft rot and were isolated from wilted plants in the field. Flavobacterium-like organisms were isolated from tubers with soft and dry rots and from potato field soil.
