Abstract
Ce polysaccharide, doté de propriétés intéressantes d'écoulement et de formation de gel, est préparé par culture de Pseudomonas sp. NCIB 11264 (ATCC 31260). Ce polysaccharide, qui peut être produit facilement avec un rendement pouvant atteindre 75 % par culture continue, possède des propriétés qui sont comparables à celles des gommes de xanthane ou autres. Il est formé d'une unité répétitive qui contient 7 unités gluco-D comprenant 1 unité de glucose substitué en position 6, unités de glucose substitué en position 4, 2 unités de glucose substitué en position 3 et 2 unités de glucose bi-substitué en positions 4,6; 1 unité galacto-D constituée par du galactose substitué en position 3; 1 unité acétate; et 1 unité pyruvate; les unités contenant un point de ramification sur le glucose bisubstitué en position 4,6 et une chaîne latérale se terminant par une unité 4,6-0-(1-carboxyéthylidène)glucose-D; il a une rotation optique Ø alpha õ22 de -15 degrés (c 0,68 H2 O).
