Identification and assessment of frequency distribution in fungi isolated from coastal Andhra Pradesh

Abstract

Marine micro flora has a wide range of importance in view of its diversity and distribution. Fungi have a large number species, and each species has their own specified characters. The main objective of the work is to isolate and identify marine fungi collected from different habitats. Methodology and results: The samples were collected and stored in tight sterile bottles and transferred to lab carefully. Fungal isolates were screened from marine water sample at different dilutions and its genus were identified and studied. All the colonies of each plate are counted by colony counter, further those pure colonies were isolated and studies are carried out to identify them. The site for the isolate collection had been studied, the regions in this area is highly diversified with different marine ecosystems. The water sample is collected at a distance 1 km away from the edges of beaches. Thus sample is analysed for taxonomical evaluation and species identification. The taxonomical study evaluated nearly for 15 spp. out of 22 isolates. Among those some isolates were identified as Aspergillus sp., Curvularia sp., Fusarium sp., and Microascus sp. These species have more diversified in its spore formation and its arrangement. Conclusion, significance and impact study: Throughout the study we tried to list out all the methodologies that will help a fresh researcher to identify a marine isolate through microscopic and macroscopic studies. Thus the coastal line of Andhra Pradesh had significant studies in isolating a valuable sp. for further development. Our study reveals, among all isolates Microascus sp., had provoked a good literature for the future research and till now its taxonomical studies are less evaluated. This would be encouraged for scientists to identify rare species to increase the evolution.

Investigation of fungi accompanying wheat grains at wheat cultivation areas in Iraq and the possibility of diagnosing it

“…The fungus Alternaria sp ranked second with a frequency of 16.22%, where it was noted that the highest frequency was for A. flavus in the provinces of Muthanna and Najaf by 43 and 34%, respectively. These results were close to what was found by [15] , when they studied wheat samples in three Bulgarian cities, and the frequency of A. favus was 44.78%. The result converged with the findings of a previous study [16], where the frequency of A. flavus in their study was 36%, this result was close to the study that was conducted in the southern provinces of the Kingdom of Saudi Arabia when examining 25 samples of grain, it was found that the frequency of A. flavus was 68% and the percentage of occurrence was 22.08% [17].…”

New Synthetic Approach to Protulactone A and Structural Analogues

“…Fungi found in marine environments are an interesting source of biologically active compounds. 1 In 2010, Sohn and Oh reported the isolation of two new polyketide-derived fungal metabolites with bicyclic scaffolds from an EtOAc extract of the marine fungus Aspergillus sp. SF-5044.…”
