Further Studies on the Water Relations of Xerophilic Fungi, Including Some Halophiles Free

Abstract

Germination and growth of six fungi, and , isolated from salt fish, and two new undescribed species from other sources, a sp. and a sp., were examined on media in which water activity ( ) was controlled over a wide range by glucose/fructose, glycerol or NaCl. Three species, and , grew more rapidly on media containing NaCl in comparison with glucose/fructose, and hence can be considered to be halophilic. Two other species, and , were also unusually tolerant of NaCl: could grow on media saturated with NaCl, while grew more rapidly on NaCl-based media down to 0·82 than any other xerophile examined so far. In contrast, the sp. was intolerant of salt. The sp. was obligately xerophilic, with growth confined to the range 0·935–0·68 .
