    Notes: The effect of inositol addition on phospholipids, cell growth, ethanol production and ethanol tolerance in a high ethanol producing Saccharomyces sp were studied. Addition of inositol greatly influenced major phospholipid synthesis. With inositol in the fermentation medium, phosphatidylinositol (PI) content was increased, while phosphatidylcholine (PC) and phosphatidylethanolamine (PE) were decreased. However, without inositol in the fermentation medium, PI content dropped down within 24 h, then increased, but was lower than in the presence of inositol. When yeast cells had a higher content of PI, they produced ethanol much more rapidly and tolerated higher concentrations of ethanol. During ethanol shock treatment at 18% (v/v) ethanol, yeast cells with a higher concentration of PI lost their viability much more slowly than those with a lower concentration of PI, indicating that the PI content in these yeast cells can play an important role in ethanol production and ethanol tolerance. Fatty acids and ergosterol were not responsible for high ethanol tolerance and high ethanol production in this yeast strain.

    New arrays of cytoplasmic microtubules in the fission yeastSchizosaccharomyces pombe (1995)

    Notes: Summary New arrays of microtubules in the fission yeastSchizosaccharomyces pombe, which distribute in the cell in a cell cycle-dependent manner, were characterized using conventional and confocal laser scanning immunofluorescence microscopy. During the interphase and prophase, we observed abundant cytoplasmic microtubules between cell poles, a peripheral network of randomly and helically distributed cortical microtubules, and perinuclear microtubules surrounding the nucleus. At the anaphase and telophase, an equatorial ring containing tubulin was visualized. This ring colocalized with an actin contractile ring, suggesting that they may control the plane of cell division cooperatively.

    Accumulation of β-tubulin-containing fibres in the cortical domain ofSaccharomyces cerevisiae spheroplasts (1998)

    Notes: Summary The distribution of microtubules inSaccharomyces cerevisiae was studied with the monoclonal antibody (mab) TU-14 against β-tubulin. Immunoblotting and immunoprecipitation experiments with a strain overexpressing Tub2p confirmed that the mab TU-14 specifically recognized Tub2p. By immunofluorescence microscopy, the mab TU-14 attached to all known tubulin structures labelled with the standard polyclonal anti-β-tubulin antibody 206-1. In addition, the mab TU-14 revealed cortical patches in wild-type cells and an abundant network of fibres in the cortex of spheroplasts cultivated in nutrient medium. These cortical fibres seemed to be specific to spheroplasts and suggest that the accumulated Tub2p is predominantly associated with the plasma membrane.

    Molecular cloning of the GTP-cyclohydrolase structural gene RIB1 of Pichia guilliermondii involved in riboflavin biosynthesis (1995)

    Notes: The structural gene of GTP-cyclohydrolase, involved in riboflavin biosynthesis, was cloned from a Pichia guilliermondii genomic library. A 1855 bp genomic DNA fragment complementing the riboflavin auxotrophies of an Escherichia coli ribA mutant, defective in GTP-cyclohydrolase II, and a P. guilliermondii rib1 mutant was isolated and sequenced. An open reading frame with the potential to encode a protein of 344 amino acids with a predicted molecular mass of 38 711 Da was detected. The P. guilliermondii enzyme shows a high degree of homology to GTP-cyclohydrolases type II from E. coli and Baccillus subtilis and to GTP-cyclohydrolase from Saccharomyces cerevisiae. Functional GTP-cyclohydrolase from P. guilliermondii may consist of four identical subunits. The sequence of the RIB1 gene of P. guilliermondii was submitted to the EMBL sequence database and is accessible under Accession Number Z49093.
