form a complete mycelium. During the early fermentation 

 the fungus produced only 1-1 per cent, by volume of alcohol, 

 whilst S. cerevisice gave 6 per cent. ; but the Monilia con- 

 tinued the fermentation, and produced at the end of six months 

 5 per cent, by volume of alcohol, whilst the culture yeast gave 

 no further quantity. 



Hansen states that Monilia does not secrete invertase, 

 but, nevertheless, ferments cane sugar, from which he con- 

 cludes that cane sugar is directly fermentable. He suggests,

however, the possibility that cane sugar may be converted 

 into invert sugar in the interior of the cells, and that the latter 

 is immediately fermented. 



Hansen's observations were confirmed by the work of E. 

 Fischer and P. Lindner, and subsequently by Buchner and 

 Meisenheimer. They proved that an inverting enzyme cannot 

 be extracted either from the fresh or from the dried vegetation.
