270 FAMILY OF SACCHAROMYCETACEAE 



nourished, this species produces ascospores after 18 hours at 25 C. 

 They are very numerous in each asc. In decoctions of cocoa this 

 yeast produces an alcoholic fermentation and forms a scum. It does 

 not invert saccharose and dies rapidly in this solution. 



YEAST FROM SALT! Hoye 1 



This species was found by Hoye in the analysis of air. This 

 author used as a nutrient medium a wheat paste to which was added 

 17 per cent of salt. It is a round yeast which forms a single spore 

 in. each asc. The best medium is a fish bouillon with 10 per cent of 

 salt added. In nutrient liquids with 3 per cent of salt, development 

 ceases completely. The different proportions of salt have no influence 

 on the shape of the cells. This yeast produces no fermentation in 

 apple juice. 



SACCHAROMYCES ANGINAE. Achalme and Troisier 2 



This species was found by Achalme and Troisier in a clinical 

 angina analogous to thrush. The cells are oval (8 to 9 by 5-6 ju), 

 isolated in groups of 8 to 10, often budding at one 

 of the poles. (Fig. 123.) In cultures, they pro- 

 duce ascs with 4 rounded ascospores (2 microns). 

 On gelatin, this yeast develops with grayish white 

 colonies, with the deep colonies brown and

SACCHAROMYCES TUMEFACIENS. (Curtis) Busse 

 Syn.: SACCHAROMYCES SUBCUTANEOUS TUMEFACIENS. Curtis 3 



This species was observed by Curtis from a tumor of the hip 

 and from a lumbar abscess in man. In the tumor it presents oval or 

 spherical cells with granular contents (16 to 20 ju) and is surrounded 

 by a gelatinous capsule (Fig. 124.) In cultures, the cells oval at first
