Cream Colored Yeast

Macroscopic Appearance A spherical yeast not forming a pseudomycelium, encapsulated by a cream to brown colored mucus. 

History, Use and/or Medical Implications A non-fermenting yeast with alliances to the Ascomycetes, Cryptococcus neoformans (Sanf.) Vuill. causes a deadly disease in animals and humans called cryptococcosis, otherwise known as Torula meningitis or yeast meningitis . This yeast attacks and reproduces in the central nervous system, particularly in the brain and spinal fluid. Symptoms begin with a stiff neck and headache and end in total or partial blindness, paralysis, coma and respiratory failure. Less severe symptoms occur in other parts of the body, for which there is a 

Comments Ciypfococcusis a non-fermenting yeast with alliances to some Ascomycetes Torula (Black Yeast), Rhodotorula (Red Yeast) and Candida. 

In 1 979 one of the containment buildings at the Tennessee Clinch River Breeder Reactor project had to be quarantined because of a massive outbreak of Ciyptococcusneoformans.

Yeast spot, caused by Nematospora coryli and N. lycopersici, can discolor soybean seed and lower oil content (Sinclair, 1999d). The mouth parts of several species of stink bug transmit these pathogens that infect the seed when the insect feeds on the embryo (Sinclair, 1999c, Russin Boethel, 1994). Early infection during pod development may lead to pod abortion while later feeding can lead to light- or cream-colored...

Crea.m Yeast. At a 5% soHds concentration in the fermentor, the yeast occupies about 12% of the fermentor volume. It is harvested by centrifugation in nozzle centrifuges and washed several times with water. The final centrifugate is cooled and stored in refrigerated tanks. This yeast cream (so called because of its off-white color) may be sold directly in this form, since in large baking faciHties, it may be piped directly to any desired location. 

The yeast film is called flor and the biological aging process has been known as crianza de flor for a long time at Xeres. The more or less rapid and intense flor formation and its aspect and color (white, cream, golden, burnt) depend on many... 

Yeast colonies produced a pink color on DRBC which facilitated its identification, whereas in OCY agar yeast colonies took on a cream or clear color. Bacterial colonies were not detected on the media. However, the presence of bacteria on DRBC was reported by Korburger et al. (1985), in their evaluation of molding ground meat and carrots. In addition, bacterial development was observed in wheat flour and corn meal samples in the latter study.
