Journal of University of Anbar for Pure Science , volume:12 issue:1

Unculturable and non sporulating fungi represent a great challenge in studying biotrophic ,endotrophic and mycorrhizal fungal groups. In this study a novel culture dependent technique complemented with PCR was used to detect and identify of unculturable fungi in soil . To develop techniques for cultivation of unculturable fungi for the purpose of expanding studies on fungal biodiversity in soil , Soil Infusion Agar (SIA) was developed . By this technique, from higher dilutions of soil five tiny colonies (less than 1mm in diameter) had grown on SIA after incubation for 1-3 months at 280C , but had not shown growth when replicated on traditional mycological media ,were selected , purified studied culturally and microscopically and identified by molecular methods . Growth of the five clones on PDA, but not Sabouraud Dextrose Agar and Czpak Dox Agar of incubation when a loopful of a colony grown after several successive subculturing on SIA was transferred to PDA. The growth on PDA has been empirically proven due to the inoculums size effect and the period of incubation at 280C. Two fungal specific primer sets (EF4F/ITS4r and EF60F/ITS4r) were used to amplify partial sequences of fungal r RNA gene included ITS sequences .The five partial sequences of the five clones were aligned through the BLASTN phylogenetic analysis against NCBI database which revealed higher identities. The blast tree showed that all clones are neighbor joined to Aspergillus ssp and Pichia sp. These results led us to consider the clones as viable but non culturable fungi (VBNC fungi) like the common phenomenon found in some bacterial species.

This research included preparation of two types of fiber composites and the the basis as ato break the stereotypes and manual volumetric rate of 25% . The characterization of the fiber is divided into two types: Overlapping material composed of epoxy resin as a subsidized two layers and four layers , six layers of fiber glass basis of the type (E-Glass) is woven mat. Overlapping material composed of epoxy as supported by two layers and four layers , six layers of caors rock wool fibers basis . In this paper the hardness characteristic study of the above complexes in natural conditions and after immersion normal water for different time periods is (5,10,15) days at room temperature . The results showed the process that the value of surface hardness for both types of specimens in natural conditions increases with the number of layers of reinforcement and that the value of the complexes fiberglass higher than the value of the complex rock wool fibers , after immersion the samples with water usual noticed that the surface hardness decreases with increasing duration of water immersion and with increasing number of reinforcement layers and both types of complexes , but their value in the complexes, fiberglass largest of its value for the characterization of rock wool fibers
