1. Yeast diversity associated to sediments and water from two Colombian artificial lakes
In Colombia, knowledge of the yeast and yeast-like fungi community is limited because most studies have focused on species with clinical importance. Sediments and water represent important habitats for the study of yeast diversity, especially for yeast species with industrial, biotechnological, and bioremediation potential. The main purpose of this study was

2. Isolamento e caracterização de leveduras fermentadoras de D-xilose, L-arabinose ou D-celobiose e produtoras de celulases e xilanases associadas à madeira em decomposição
Security of a sustainable energy supply providing alternatives to fossil fuels, and market demands are controlling parameters for developing new energy systems, being bioethanol a part of the solution to this problem. The aims of this study were to isolate, identify and characterize yeasts producing exoenzymes and capable of fermenting xylose, arabinose and/

3. Leveduras micocinogênicas de solos da Estação Ecologica de Maracá, Roraima-Brasil
Duzentos e quarenta linhagens de leveduras foram isoladas de amostras de solos da Estação Ecológica de Maracá, na Amazônia Brasileira, as quais representam 82% de leveduras de afinidade ascomicética e 18% basidiomicética. As especies dominantes foram Candida etchellsii, Candida famata, Candida robusta, Candida rugosa, Candida valida, Debaryomyces hans

4. Identificação de leveduras isoladas do Rio Una do Prelado, na Estação Ecologica de Jureia-Itatins, SP
A microbiota de leveduras associada à água do Rio Una do Prelado da Estação Ecológica de Juréia-Itatins (Peruíbe-SP) foi estudada em três pontos distintos: rio, mangue e estuário. Foram isoladas linhagens de leveduras e fungos leveduriformes. Das leveduras isoladas, 91 % do total se encontram no estado anamorfo, com característica de leveduras asco

6. DNA sequences coding for the ribosomal small subunit RNA and valyl tRNA from the linear mitochondrial genome of the yeast Williopsis mrakii.

7. Linear mitochondrial DNAs of yeasts: frequency of occurrence and general features.
In most yeast species, the mitochondrial DNA (mtDNA) has been reported to be a circular molecule. However, two cases of linear mtDNA with specific termini have previously been described. We examined the frequency of occurrence of linear forms of mtDNA among yeasts by pulsed-field gel electrophoresis. Among the 58 species from the genera Pichia and Williopsis

8. Linear mitochondrial DNAs of yeasts: closed-loop structure of the termini and possible linear-circular conversion mechanisms.
The terminal structure of the linear mitochondrial DNA (mtDNA) from three yeast species has been examined. By enzymatic digestion, alkali denaturation, and sequencing of cloned termini, it was shown that in Pichia pijperi and P. jadinii, both termini of the linear mtDNA were made of a single-stranded loop covalently joining the two strands, as in the case of

9. Prevention of Yeast Spoilage in Feed and Food by the Yeast Mycocin HMK
The yeast Williopsis mrakii produces a mycocin or yeast killer toxin designated HMK; this toxin exhibits high thermal stability, high pH stability, and a broad spectrum of activity against other yeasts. We describe construction of a synthetic gene for mycocin HMK and heterologous expression of this toxin in Aspergillus niger. Mycocin HMK was fused to a gluco
