Abstract

Abstract The carotenoid pigments of the Gram-negative bacterium Pseudomonas rhodos were identified as 4,4′-diapocarotene-4-oic acid, di (β,ᴅ-glucosyl) 4,4′-diaptocarotene-4,4′-dioate, and β,ᴅ-glucosyl-4,4′-diapocarotene-4-oate-4′-oic acid. One hydroxy group of the glucose moieties, probably at C (6), was esterified with one of several fatty acids (12:0, 14:0, 14:1, 16:0, 1 6 :1).
