Response of the Higher Basidiomycetic Ganoderma resinaceum to Sodium Chloride Stress

ABSTRACT

Ganoderma resinaceum tolerated sodium chloride salt stress within a range of 0 mM till 300 mM. It responded to salt stress with fluctuation in proline formation at different NaCl concentrations. However,the mycelial dry weight,total protein contents and exopolysaccharides did not changed considerably. Increasing sodium chloride concentration led to morphological alteration in fungal mycelia with disappearance of fungal cell wall,plasmolysis,and vacuolation as indicated with electron microscopic examination of the fungal growth.
