Abstract
The growth, both radial and as biomass expressed by 13 fungal species from alkaline soils at two localities in the Makkah district was studied. No obligate alkaliphile was found but facultative alkaliphile was shown by Cylindrocarpon heteronemum and Acremonium strictum, while Fusarium moniliforme appeared to be highly alkaline-tolerant. Fast growing fungi such as Rhizopus nigricans, Cunninghamella elegans, Rhizoctonia solani and Arthrobotrys oligospora were alkaline-sensitive. Slower growing species were, on the other hand, alkaline-tolerant. A positive correlation was found between the level of alkaliphile and the frequency of occurrence in Saudi soils of the Makkah district.
