✦ Synopsis

The structure of an acidic exopolysaccharide of two strains of Pseudomonas marginalis, a bacterium which causes soft rots of various vegetables, has been determined to consist of a repeating unit of: -4)

1-The glucose is pyruvated at O-4 and O-6 and the mannoseis acetylated at either O-2 or O-3.

RESULTS AND DISCUSSION

From 40 agar plates, the strains yielded the following amounts of crude EPS: 76 and 173 mg of noncapsular and capsular EPS, respectively, for strain PF-05-2; and 329 and 57 mg of noncapsular and capsular EPS, respectively, for strain PM-LB-l. Each
