Cryptococcus laurentii albidus

Kooiman separated exocellular amylose formed in liquid media at pH < 5 by Cryptococcus albidus and Cryptococcus laurentii var. flavescens NRRL Y-1401 from a polysaccharide containing D-man-nose, D-xylose, and D-glucuronic acid. X-Ray diffraction patterns of the retrograded amyloses were identical with that of tuber starch (B modification). Periodate oxidation, optical rotational measurements, and hypoiodite oxidation data suggested a linear a-D-(l—>4)-linked structure having a chain length of about 44 units for the Cr. albidus amylose. Cryptococcus neoformans produces a crystalline amylose that was isolated by the method of Schoch. It has an iodine value and alpha- and hefa-amylase hydrolysis characteristics similar to those of corn amylose.

A number of heteropolysaccharides resembling that of Cr. laurentii in sugar composition have been isolated from Cryptococcus diffluens (Torulopsis rotundata) (now Cryptococcus albidus var. diffluens). ... 

Rhodotorula mucilaginosa, Rh. minuta, Sporobolomyces albidus, and Sp. salmonicolor, but present in Cryptococcus diffluens. However, Meyer (49) clearly demonstrated such activity in the intracellular extract and in the cell walls of Rhodotorula minuta var. texensis, Rh. glutinis, Cryptococcus albidus, Cr. terreus, and Cr. laurentii. The activity in the cell walls of these yeasts was always much higher than that of the intracellular extract. 0-(l- 6)-Glucanase activity of these species was either lacking or extremely low, but chitinase activity was significant in most strains.
