the aim of this study was to evaluate the performances of methods such as sequencing of the internal transcribed spacer (its) and 26s (d1/d2) regions of ribosomal dna, rflp analysis of the its region and commercial biochemical test kit for the identification of the yeasts isolated during spontaneous fermentation of fresh crushed pineapple juice. the experiments were conducted in thailand and au...

Black yeast fungi play critical role in degradation of petroleum polluted soils. Little attention has been paid to the biodiversity of black yeast fungi in Iran. In this paper, diversity of black yeast fungi was studied in petroleum polluted soils in Tabriz and Urmia regions. Soil samples were collected from petroleum polluted areas in vicinity of oil storage tanks in Tabriz and Urmia cities (E...

Abstract Yeasts, usually defined as unicellular fungi, occur in various fungal lineages. Hence, they are not a taxonomic unit, but rather represent lifestyle shared by several unrelated Although the discovery of new yeast species occurs at an increasing speed, current rate it will likely take hundreds years, if ever, before all be documented. Many parts earth, including many threatened habitats...

In the present study basidiomycetous yeast species were characterised from soil samples in different regions of Iran. Soil samples were collected from 5–15 cm depth, subsequently yeasts were isolated and purified. Yeast isolates were identified using D1/D2 domains of 26S rRNA and physiologic tests. The results of this study revealed a rich diversity amongst basidiomycetous yeast species in the ...

Due to the importance of Saccharomyces cerevisiae in wine-making, the genomic variation of wine yeast strains has been extensively studied. One of the major insights stemming from these studies is that wine yeast strains harbor low levels of genetic diversity in the form of single nucleotide polymorphisms (SNPs). Genomic structural variants, such as copy number (CN) variants, are another major ...

In this review we describe the role of the yeast Saccharomyces in the development of human societies including the use of this organism in the making of wine, bread, beer, and distilled beverages. We also discuss the tremendous diversity of yeast found in natural (i.e., noninoculated) wine fermentations and the scientific uses of yeast over the past 60 years. In conclusion, we present ideas on ...

Background and Objective: Milk is a completely rich and complex environment suitable for different microorganisms including bacteria and Fungi. The majority of studies were conducted on milk-bacterial flora and aflatoxin-contaminations in dairy products; however, despite the importance of yeasts in usage as starter in the dairy industries and their effect on the taste of dairy products as well ...
