At High Aw Growth Of P. Pisce Was Similar On Media Containing Either Solute, But Below 0·90 aW Growth Was More Rapid On Nacl Media, Indicating That P. Pisce Can Be Classified As A Halophilic Fungus. The Minimum aW For Growth On Nac1-Based Media Was 0·746; On Glucose/Fructose Media The Minimum Was 0·700 aW. Optimal Growth, I.E. Growth At 80% Or More Of The Maximum Growth, Occurred Between 0·96 And 0·91 aW at 30 °C. Over the wide range of temperatures studied, B. halophila exhibited more rapid growth on NaCl media than on glucose/fructose media over the entire range of aW at which growth occurred. The optimal growth rate on NaCl- based media occurred between 0·89 and 0·86 aW, an exceptionally low value. B. halophila can be classified as an extreme halophile, markedly intolerant of high aW, particularly on glucose/fructose-based media at temperatures above 30 °C. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-134-8-2255
