Abstract

Growth Characteristics Of And , Two Fungi Isolated From Dried Salt Fish, Were Examined At 20, 30, 34 And 37 °C Over A Range Of Water Activity (a) Values (0·99–0·70) On Media Containing Various Concentrations Of Nacl Or Glucose/Fructose. At High Aw Growth Of Was Similar On Media Containing Either Solute, But Below 0·90 a Growth Was More Rapid On Nacl Media, Indicating That Can Be Classified As A Halophilic Fungus. The Minimum a For Growth On Nac1-Based Media Was 0·746; On Glucose/Fructose Media The Minimum Was 0·700 a. Optimal Growth, I.E. Growth At 80% Or More Of The Maximum Growth, Occurred Between 0·96 And 0·91 a at 30 °C. Over the wide range of temperatures studied, exhibited more rapid growth on NaCl media than on glucose/fructose media over the entire range of a at which growth occurred. The optimal growth rate on NaCl- based media occurred between 0·89 and 0·86 a, an exceptionally low value. can be classified as an extreme halophile, markedly intolerant of high a, particularly on glucose/fructose-based media at temperatures above 30 °C.
