G oldstein , S olomon . (Yale U., New Haven, Conn.) Studies of two polycentric chytrids in pure culture. Amer. Jour. Bot. 48(4): 294–298. Illus. 1961.—A study was made of some of the chemical and physical factors affecting the growth of Nowakowskiella elegans Schroeter and N. ramosa Butler in pure culture. Maximal harvests of the former were obtained at 15°C. and those of the latter fungus at 20°C. Media buffered at pH 6.4 favored their growth; light had no effect upon yields; and harvests increased markedly in response to shaking. Both fungi required an exogenous supply of thiamin with maximum yields obtained upon incorporating 10μg./l. of the vitamin into a thiamin‐deficient medium. Inorganic nitrogen salts and several organic nitrogen compounds were readily metabolized by these water molds. The use of xylose, glucose, or mannose as the sole source of carbon gave optimal yields of both organisms and neither utilized a variety of sugar acids and alcohols.
