Yeast succession in the Amazon fruit Parahancornia amapa as resource partitioning among Drosophila spp
Article Abstract:
The differences in the yeast community in the Amazon fruit, Parahancornia amapa, compared to other fruits of the forest are due to competitive interactions among yeast species and the Drosophila-mediated selective dispersion. Yeasts of the amapa fruit assimilate simple carbon sources such as glycerol, cellobiose, and salicin. Drosophila flies, that feed selectively on yeast patches 3 to 10 days after the fruit falls, help in diversifying the yeast species which increases with the decay of the fallen amapa fruit.

A mitochondrial molecular marker, ori-rep-tra, for differentiation of yeast species
Article Abstract:
A study of six yeast isolates produced from clinical material to investigate the presence of ori-rep-tra sequence showed that the evolution of this sequence in the mitochondrial genome was late during the evolution of Saccharomyces group indicating that the use specific molecular probes such as ori-rep-tra is a suitable methods for quantitative and qualitative analysis of complex microbiological processes.

New hybrids between Saccharomyces sensu stricto yeast species found among wine and cider production strains
Article Abstract:
A study was conducted to analyze two yeast isolates for their nuclear and mitochondrial genomes. Fermentative characteristics were examined. Experimental results indicated that the strains supported hybrids between Saccharomyces cerevisiae and Saccharomyces bayanus. Findings also showed that the strains had different restriction patterns of mitochondrial DNA and different sequences of the OL11 gene.
