Reniforma strues, a new yeast from wastewater.
Mycologia 1990 Sep/Oct; 82(5):549-553
A new yeast isolated from wastewater was characterized. The new yeast, named Reniforma-strues, was detected and isolated from the biological film of a rotating biological contactor at the wastewater treatment facility for Morgantown, West Virginia. Samples of the yeast were collected and cultured on yeast extract malt extract agar (YM agar). When cultured on YM agar, R-strues produced budding kidney shaped somatic cells having a flat base circumscribed by a brim. It grew weakly in glucose yeast peptone water and vitamin free medium. It grew rapidly on YM agar. It did not ferment sugars. It assimilated only D-glucose, mannitol, and citric-acid. It hydrolyzed urea and reacted with diazonium-blue-B (DBB). It did not form starch like compounds or DNAase or amylase. The authors conclude that R-strues can be classified as a basidiomycetous yeast on the basis of its structure and its ability to produce urea and react with DBB.
