. Bulletin. Agriculture. Some New Varieties of Mycoderma Yeast. 399 MYCODERMA YEAST S (PI itc XXVIII S), FOUND IN THE AIR OF A SAKE FACTORY. GENERAL CHARACTERIS' Chiefly round and very rare el- lipse. The cell con- tents are very briglit 2'5-5 ja. b., On knji-extract cr wort it forms a ring at common tempeiature, but on an artificial solution containing alcohol (Nageli"s solution), or glycerin instead of sugar (liayduck's. solution) or Hayduck's solution shows a very energetic growth. It forms on wort- gelatine a waxy conical co'ony with a ring-like canal near the top of the colony.

It forms on wort- gelatine a waxy conical co'ony with a ring-like canal near the top of the colony. Streak culture on wort cr kdji-extract gelatine gives a white waxy coating. It liquefies gelatine very slowly. Giant colonies- on wort-gelatine are a white, elevated mass of waxy nature. On the central part some petal-like figures radiate from centre very similar to that of S. hyalos- poriis. On sugar-bouillon-agar it gives rather flat and waxy colonies. Ferments only glu- cose. Assi- milates glu- cose, sac- charose but not maltose. Optimum temp. 27-30° C. Killing temperature lies at 54'4° C.
