Abstract
The present study has been investigate the fungal species which lived in Shatt Al –Arab River, and the ability of some of them to produce lipase, as well as the effect of salinity on the activity of lipase production. Different species of fungi were isolated from water at the sites: Al-Faw , Abu - Floos Port and Ashar during the period 3/3 -29/9/2005.True aquatic fungi belong to Saprolegniaceae were isolated from Abu- Floos Port and Ashar during March and April, with no sign of their occurrence in Al- Faw. A lot of different fungal species which belong to Deuteromycetes, few of Ascomycetes, and very few belong to Zygomycetes were isolated. The activity of ten species were investigated for production of lipase . It is appeared that seven species have the ability to produce this enzyme. The most active fungi was Alternaria chlamydospora followed by Aspergillus candidus and Fusarium sp. and the lowest activity was the fungi Stachybotrys sp. and Scytalidium lignicola. The effect of salinity on the lipase activity of seven fungal species was examined at salty concentration 15 , 20 , 25 , 30 , 35 and 40 ppt, they have show significant effect in the reduce of redial growth and the lipase production by these fungi.
