ABSTRACT
Two halophilic fungal isolates named Trichoderma piluliferum fs. Halophila AZ and Aspergillus restrictus were isolated from Sharm El-Sheikh and from Raas Sader regions at Sinai–Egypt. They tolerates till 30 and25 %( w/v) NaCl (respectively). The former required at least 5% (w/v) NaCl, while the second grew poorly at salt free medium. Morphogenesis and ultrastructure of the two fungal isolates revealed that, 10 – 20 % NaCl concentration was the best for normal growth and cell ultrastructure and .It is worth to mention that this is the first record for true obligate halophilic fungal isolate (Trichoderma piluliferum fs. halophila AZ). The two fungal isolates could be used in many biotechnological applications.
