“…A small layer of fungal mycelia, approximately 1cm diameter of mycelial layer, was inoculated in the petroleum-czapek dox broth. The media was incubated at 34-37°C for 35-40 days in shaker incubator rotating at 68 rpm (Hasan et al, 2014;Alwakeel, 2017). The inoculation was examined once a day without disturbing the culture media.…”

Hydrocarbon of crude oil and other oil products such as gasoline comprise aromatic, aliphatic and alicylic components pollute water bodies are hazardous. Microbial degradation of these oil spills are an efficient way. Degrading oil contamination by microorganism is the theme of this paper. To study degrading efficiency of crude oil hydrocarbon by fungi. Fungal species were isolated from crude oil soaked soil samples and oil contaminated soil samples from commercial oil industry. Isolated fungal species were cultured on nutrient media such as potato dextrose agar (PDA) and czapekdox agar at 37 ºC for 7 day. Further, fungal species were identified by 18 S rRNA sequencing. The potential of fungi to degrade hydrocarbon was investigated through laccase and peroxidase. To examine the ability to degrade oil, the fungal species were screened on Czapekdox agar and broth medium containing petroleum derivatives. Laccase activity was performed by ABTS (2, 2̍-azinobis 3ethyl-benzothiazoline-6-sulphonate) and bromophenol. They were used as substrate for screening laccase activity. Among the isolated eight fungal species, isolate FGS-4 showed better biodegradation ability and subsequent 18 S rRNA revealed that isolate FGS-4 belongs to Aspergillus tubigensis. Production of laccase enzyme was confirmed. The results of gas chromatography analysis showed that hydrocarbon was biodegraded by the isolated Aspergillus tubigensis. Biodegradation of hydrocarbon by Aspergillus species would create an impact on various waste treatment methods. Eco-friendly degradation of hydrocarbons could be achieved by Aspergillus species.

“…They are easily isolated and grown in the lab which makes it safer for the marine environment. The extreme conditions of marine life have caused fungi to become stress-resistant by forming many useful secondary metabolites (Alwakeel, 2017). These metabolites are said to have important biological activities including antimicrobial, anticancer, antioxidants and even antidiabetic, which is one of the reasons fungi are becoming more popular in marine drug discovery research (Hasan et al, 2015).…”

Marine life has provided mankind with unique and extraordinary chemical structures and scaffolds with potent biological activities. Many organisms and secondary metabolites derived from fungi and symbionts are found to be more environmentally friendly to study than the marine corals per se. Marine symbionts such as Aspergillus sp., a fungus, which can be isolated and grown in the lab would be a potential and continuous source of bioactive natural compounds without affecting the marine environment. The Red Sea is known for its biodiversity and is well-studied in terms of its marine-derived bioactive metabolites. The harsh environmental conditions lead to the development of unique metabolic pathways. This, in turn, results in enhanced synthesis and release of toxic and bioactive chemicals. Interestingly, the Persian Gulf and the Gulf of Oman carry a variety of environmental stresses, some of which are similar to the Red Sea. When compared to the Red Sea, the Persian Gulf has been shown to be rich in marine fungi as well, and is, therefore, expected to contain elaborate and interesting bioactive compounds. Such compounds may or may not be similar to the ones isolated from the Red Sea environment. Astoundingly, there are a very limited number of studies on the bioactive portfolio of marine-derived metabolites from the Persian Gulf and the Gulf of Oman. In this perspective, we are looking at the Red Sea as a comparator marine environment and bioactive materials repertoire to provide a futuristic perspective on the potential of the understudied and possibly overlooked bioactive metabolites derived from the marine life of the Persian Gulf and the Gulf of Oman despite its proven biodiversity and harsher environmental stress.

p-diphenol:dioxygen oxidoreductase) are a group of multicopper containing enzymes mostly produced by group of white rot fungi. In the present study we have isolated and identified as potential laccase producing Pleurotus ostreatus and Pleurotus cystidiosus from Yelagiri Hills and the gene bank accession number were MH591762 and MH591763. The laccase production was screened using plate assay method and P.cystidiosus was found to be the maximum producer, it's a first report for the production of laccase.
