Glucuronomannans

Glucuronomannans. Most glucuronomaimans occur as components of certain plant gums and are characterized by the presence of an 0-(P -D-glucurono-pyranosyl)-(1 2)-D-maimopyranosyl linkage ia the molecule (65). Less complex glucuronomaimans are found in the tissues of bracken Pteridium aquilinum) and in tobacco leaf cells where they may be part of the cultured cell wall (132) and exude into the medium in which the cells are grown (133).

Lipomyces. When component analyses were first carried out on heteropolysaccharides from these soil yeasts, it was recognized that the compositional differences had taxonomic value (18). As shown in Table III, polysaccharides from L. lipofer are glucuronomannans while those from strains of L. starkeyi also contain residues of g"galactose. Both types are 0-acetylated. It was further noted that acid hydrolysis liberated from L. starkeyi...
