“…This provided Mohamed Abdel-Wahab (Botany Department, Faculty of Science, South Valley University, Sohag, Egypt) the possibility to publish his pioneering study on the Egyptian obligate mangrove-inhabiting fungi of the Red Sea in 1996. Three contributions of El-Sharouny et al (1998, 1999) and Abd-Elaah (1998) shed light on the ecology and taxonomy of mangrovicolous, algicolous and aquatic fungi of the Red Sea in Upper Egypt. Abdel-Wahab (2000) obtained his PhD on the biodiversity of fungi in subtropical mangroves; he recorded 25 fungi on intertidal wood of Avicennia marina collected from three mangrove stands of the Red Sea coast of Egypt.…”

Records of Egyptian fungi, including lichenized fungi, are scattered through a wide array of journals, books, and dissertations, but preliminary annotated checklists and compilations are not all readily available. This review documents the known available sources and compiles data for more than 197 years of Egyptian mycology. Species richness is analysed numerically with respect to the systematic position and ecology. Values of relative species richness of different systematic and ecological groups in Egypt compared to values of the same groups worldwide, show that our knowledge of Egyptian fungi is fragmentary, especially for certain systematic and ecological groups such as Agaricales, Glomeromycota, and lichenized, nematode-trapping, entomopathogenic, marine, aquatic and coprophilous fungi, and also yeasts. Certain groups have never been studied in Egypt, such as Trichomycetes and black yeasts. By screening available sources of information, it was possible to delineate 2281 taxa belonging to 755 genera of fungi, including 57 myxomycete species as known from Egypt. Only 105 taxa new to science have been described from Egypt, one belonging to Chytridiomycota, 47 to Ascomycota, 55 to anamorphic fungi and one to Basidiomycota.

“…The activity of GOT was observed in the samples of Fusarium solani and Fusarium oxysporum and not detected in other isolates of Fusarium. 7 They studied the activity of transaminases enzyme in several fungus. Neither they studied the activity of transaminases in S. schenckii nor studied the effect of KI with varied concentration on it.…”

Background : Sporotrichosis is chronic, pyogranulomatous fungal infection of cutaneous or subcutaneous. It is caused by the dimorphic fungus Sporothrix schenckii (S. schenckii). Aims: This study describes the in-vitro effect of potassium iodide (KI) on the transaminases enzymes, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) produced by the filamentous form of S. schenckii. Methods and Material: A master culture of S. schenckii was prepared in YNB (Yeast nitrogen base) medium and was incubated at 25ºC (mould). KI was added into the YNB medium in increasing concentrations. One mL suspension of master culture was inoculated into each bottle and incubated at 25ºC for different time period, 4 th day (early-log period), 9 th day (mid-log period) and 14 th day (peak of growth) respectively. After centrifuging, a 5% homogenate was prepared that was used for transaminases enzyme assay. Results: The mean aspartate aminotransferase level of control specimen was 12.4 ± 3.30, 22.4 ± 3.69 and 53.6 ± 8.46 IU on day 4, 9 and 14 respectively. The mean aspartate aminotransferase level of test specimen was ranged from 3.5 ± 0.80 (KI 6.4 gram %) to 12.4 ± 4.66 IU (KI 0.1 gram %), 2.6 ± 0.21 (KI 6.4 gram %) to 29.5 ± 7.31 IU (KI 0.05 gram %) and 2.5 ± 0.23 (KI 6.4 gram %) to 42.3 ±3.70 IU (KI 0.2 gram %) on day 4, 9 and 14 respectively. The mean alanine aminotransferase level of control specimen was 17.5 ± 5.93, 24.6 ± 3.59 and 32.6 ± 7.54 IU on day 4, 9 and 14 respectively. The mean alanine aminotransferase level of test specimen was ranged from 2.2 ± 0.00 (KI 6.4 gram %) to 15.4 ± 2.36 IU (KI 0.1 gram %), 2.7 ± 0.81 (KI 6.4 gram %) to 29.5 ± 2.75 IU (KI 1.6 gram %) and 3.5 ± 1.37 (KI 6.4 gram %) to 29.6 ± 2.82 IU (KI 0.2 gram %) on day 4, 9 and 14 respectively. Conclusions: At the entire test concentrations mean value was lower as compared to control. The low activity of the transaminases enzymes indicates that KI has inhibitory effect on the growth of S. schenckii (mould) and has led to decrease in the activity of these enzymes.

“…Earlier studies on marine fungi in the Red Sea and other briny bodies of water have recognized the prevalence of the following fungal species: Ascomycota, Basidiomycota and mitosporic fungi (Simo˜es et al, 2015). Other studies also found Candida, Cryptococcus, Debaryomyces and Rhodotorula prevalent in seawater (Abd-Elaah, 1998). It has been confirmed that the extreme conditions conferred by the environment of the Red Sea and other similarly hostile environments such as the black sea have enabled eukaryotes especially fungi to substantially evolve and develop stress-resistant mechanisms to cope with their new ecological niches (Wang et al, 2014).…”

To isolate fungal communities from coastal areas of the Red Sea in Saudi Arabia and identify and classify them by molecular techniques. Samples were collected from the seaside of the Red Sea in Jeddah, Saudi Arabia during March 2012 and stored in sterile screw cap bottles for further analysis. Phenotypic and genotypic characterization of fungal isolates were done using standard techniques. Eight fungal genera including Aspergillus, Penicillium, Thielavia, Fusarium, Emericella, Cladosporium, Scytalidium and Alternaria. Most isolated fungi showed significant growth on petroleum media and were thus considered capable of biodegradation of crude oil based substances. The fungal genera isolated from the Red Sea had 97-100% similarity with the related fungi recorded in the GenBank in which they were deposited. The morphological and molecular structure of these marine fungal isolates closely resembles their terrestrial counterparts in the Gen-Bank. The capabilities of these fungal species to utilize petroleum as a source of carbon speaks to future applications in which marine fungi may be utilized in the breakdown of petroleum-based waste in an ecologically efficient manner.
