Marine ecosystems are least explored niches for yeast population and diversity. The present study aims to construct a comprehensive DNA barcode library for marine derived yeast species. As, we sequenced ITS gene for 1017 isolates belonging to 157 marine derived yeast species in 55 genera, 28 families, 14 orders, 8 classes of 2 Phyla (viz., Ascomycota and Basidiomycota) among which 13 yeast species were barcoded for the first time, we witnessed yeast species of both terrestrial and endemic marine origin. Difficulties were faced in taxonomic sequence validation due to large volume of sequencing trace files, variable length of sequences extracted and lack of reference sequences in public databases. Majority of the sequences (62.24%) were between 600 and 649 bps in length. K2P intra-species distance analysis conducted for selective groups yielded the average of 0.33% which was well within the previously proposed barcode gap value for yeast species (1.59%). ITS gene tree based identification conducted for selective species in Ascomycota and Basidomycota, precisely clustered the same species in single groups. About 60% of the yeast species recorded in the present study was previously unrecorded from the marine environment, among which 16.5% of yeast species were recognised human pathogens. Apart from releasing the barcode data in GenBank, provisions were made to access the entire dataset along with meta-data in the Barcode of life database under the project title “DNA barcoding marine yeast”. The present study constitutes the biggest dataset for the collection of marine yeast isolates and its DNA barcodes till date.

“…Polyols (polyhydric alcohols) are sugar derivatives in which the aldo or keto group has been reduced to the corresponding hydroxyl group with the general formula HOCH 2 (CHOH) n CH 2 OH. They are one of the most abundant classes of organic molecules that have many biologically significant roles in marine yeasts [1]. Marine yeasts produce large amounts of polyols during their growth in their natural habitats to overcome the high external osmotic pressure of the marine environment [2].…”

“…Glycerol (1,2,3-propanetriol) is used in manufacturing of food additives, cosmetics, paints, paper and leather as well as in the production of pharmaceutical formulating agents [5]. Moreover, it is a significant precursor for production of appreciated chemicals such as biodiesel, butanol, hydrogen, acrolein, citric acid, dichloro-2-propanol (DCP), 1,3-propanediol (1,3-PD), and 1,3-dihydroxyacetone (DHA) [1]. * Corresponding authors at: Suez University E-mail addresses: am_rasmey@yahoo.com (Abdel-Hamied M. Rasmey) Conversion of agro-industrial wastes such as fruit peels to glycerol can be an economic promising task.…”

Agro-industrial wastes in Egypt are indefinite and sustainable substrate for production of numerous industrially significant products. Using of these wastes as raw materials can reduce both the production cost and the environmental pollution. The present research aims to produce glycerol from fruit peels by the UV-mutant marine yeast Wickerhamomyces anomalus HH16-MU15. Fruits (banana, orange, mango and pomegranate) peels were pretreated by mechanical and hydrothermal methods before their fermentation into glycerol. The maximum total reducing sugars (5.792 ± 0.16gl-1) was obtained from mango peels followed by orange peels (5.33 ± 0.21gl-1) after their hydrothermally pretreatment. After fermentation, the maximum cellulase activity (8.911 Uml-1), total reducing sugars (48.59 gl-1) and glycerol yield (35.25 gl-1) by W. anomalus HH16-MU15 were achieved in the hydrolysate of hydrothermally pretreated orange peels at 96 hrs. The current investigation suggests the using of orange peels for production of glycerol and other valuable products by W. anomalus HH16-MU15.
