Goldstein, Solomon. (Brooklyn Coll., Brooklyn, N.Y.) Development and nutrition of new species of Thraustochytrium. Amer. Jcur. Bot. 50(3): 271‐279. Illus. 1963.—The life cycles of 2 lower Phycomycetes in sea‐water‐pollen culture are described and compared with variations observed in nutrient media. Some ecological implications are discussed. Both fungi are obligately marine and stenohaline. Maximal growth occurred with 2.5 and 3.0% NaCl not replaceable by KCl. However, omission of KCL from media resulted in reduced yields. Salinity optima were not temperature‐dependent and the organisms grew best at 12–25 C. Neither organism assimilated nitrogen in the form of KN0 3 or (NH 4 ) 2 SO 4 . Optimal harvests were obtained with glutamate as the source of nitrogen and with carbon supplied as glucose, maltose, soluble starch, or cellobiose.
