Description of gen. nov. based on taxogenomic analysis, with two new species, f.a., sp. nov. and f.a., sp. nov.

Four yeast isolates obtained from tree bark and fermenting sap of spp. and insects in Colombia and Japan were phylogenetically related to based on analyses of the sequences of the internal transcribed spacer (ITS) region and the D1/D2 domains of the large subunit rRNA gene. The novel species differs from by 20 nt substitutions and 5 indels in the D1/D2 sequences.

f.a, sp. nov., a novel yeast species isolated from rotting wood in Brazil and Colombia.

Three yeast isolate candidates for a novel species were obtained from rotting wood samples collected in Brazil and Colombia. The Brazilian isolate differs from the Colombian isolates by one nucleotide substitution in each of the D1/D2 and small subunit (SSU) sequences. The internal transcribed spacer (ITS) and translation elongation factor 1-α gene sequences of the three isolates were identical.

Ethanol production by Saccharomyces cerevisiae using lignocellulosic hydrolysate from Chrysanthemum waste degradation.

Ethanol production derived from Saccharomyces cerevisiae fermentation of a hydrolysate from floriculture waste degradation was studied. The hydrolysate was produced from Chrysanthemum (Dendranthema grandiflora) waste degradation by Pleurotus ostreatus and characterized to determine the presence of compounds that may inhibit fermentation. The products of hydrolysis confirmed by HPLC were cellobiose, glucose, xylose and mannose.
