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

摘要: Germination and growth of six fungi, Basipetospora halophila, Polypaecilum pisce, Aspergillus penicilloides, A. wentii, Eurotium repens Exophiala werneckii, isolated from salt fish, two new undescribed species other sources, a Geomyces sp. sp., were examined on media in which water activity (a w) was controlled over wide range by glucose/fructose, glycerol or NaCl. Three species, B. P. pisce Ex. grew more rapidly containing NaCl comparison with hence can be considered to halophilic. Two penicilloides A, also unusually tolerant NaCl: could grow saturated NaCl, while wentii NaCl-based down 0.82 a w than any xerophile so far. In contrast, the intolerant salt. The obligately xerophilic, confined 0.935-0.68 a w.
