SACCHAROMYCOPSIS. 383 



It ferments dextrose, maltose, and saccharose, as well as 

 <Z-mannose and dextrin. According to Lepeschkin, 8. mellacei 

 may also form a mycelium (see S. Pombe). 



According to investigations made by P. Greg in the author's 

 laboratory, divergencies of a marked and permanent character 

 distinguish the species belonging to this type. Thus some 

 yield malodorous products in the fermenting liquor, some very 

 fine products, whilst others differ greatly in the length of time 

 required to complete the fermentation in one and the same 

 sterilised molasses and dunder under identical conditions. The 

 amount of alcohol produced by these types varied from 6-6 to 

 7-6 per cent, by volume. The rate of multiplying also differed 

 widely in these species. Further details relating to comparative 

 results in practice are given in papers by Greg as well as by Hart, 

 who has carried out rum-fermentation with ellipsoidal species. 



In the author's laboratory Schizosaccharomycetes have been 

 found by Holm in Grecian wine must, on cocoa beans, and on 

 Mohwa flowers from Cawnpore. 



Saccharomycopsis guttulatus or Saccharomyces guttulatus 

 (Robin) Wilhelmi 



was found by Remack in 1845 in the contents of the stomach 

 and intestines of a rabbit, and subsequently described by 

 Robin under the name Cryptococcus guttulatus. 

 Both classified it amongst the yeast fungi. 

 In 1896 Buscalioni gave a comprehensive 

 morphological description of the organism, 

 which he named S. guttulatus. We are in- 

 debted to Wilhelmi for the following descrip- 

 tion (Schionning has associated this form 

 with one described by him as Saccharomy- 

 copsis capsularis). The cells are elliptical and 

 longish - oval with blunt ends. The length Fig- ss. 



varies from 6 to 16 ^ width 2 to 4/u. They ""fSSSSSS"' 

 contain abundant quantities of glycogen. 

 With poor nourishment, from two to four large and strongly- 

 refracted vacuoles are observed. Budding is linear or spiral. 

 Under favourable conditions of nutriment the buds will be
