Effect of Salinity on the Fungal Occurance in Al-Shega Area at Al-Qassim, Saudi Arabia

Mona S.S. Al Tamie    

Abstract: The present study included isolation, identification and evaluation of physiological traits of some halotolerant fungi isolated from soil samples taken from Al-Shega province at Al-Qassim region. The results revealed the existence of seventeen species belonging to ten genera. The most frequent genus was Aspergillus from which the isolates were detected. High fungal growth rate was observed at low salt concentrations while at high salt concentrations, the fungal growth was reduced. Emericilla nidulans has achieved the first place in the ability to grow and survive in salt concentration of 15%. All isolates vary in their growth rate at pH values of 6.5 and 8, Acremonium rutilum, Fusarium chlamydosporum, Aspergillus pulverulentus and Fusarium oxysporum showed the highest growth rate. Results indicated that Emericilla nidulans, Syncephalastrum racemosum, Aspergillus fumigates, Aspergillus parasiticus and Ulocladium atrum could grow at all degrees of temperatures (30, 40 and 50°C) and also under low and moderate concentrations of NaCl (0, 5 and 10%) but the concentration of 15% NaCl only could not encourage the growth of Emericilla nidulans under 30°C. Cephalosporium humicola, Mucor racemosus, Aspergillus parasiticus, Ulocladium atrum and Aspergillus flavus could grow on the nickel (Ni) concentration of 0.25 and 0.5% but the concentration of 1% stopped fungal growth. For a shot of all the isolated fungi grew on the lead concentrations of 0.25 and 0.5%. All fungal isolates were sensitive to cadmium. All fungus showed allergy sensitivity to cadmium (Cd), since they were not able to grow in the presence of Cd ions.
