    Extracellular amylolytic system of the yeast Lipomyces kononenkoae (1979)
    Springer
    Applied microbiology and biotechnology 6 (1979), S. 241-250

    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Summary A strain of the yeast Lipomyces kononenkoae which converted starch into SCP with a high yield, produced three extracellular amylases which were purified from the culture fluid by Ficoll concentration, dialysis, isopropanol precipitation and DE-cellulose chromatography: an α-amylase, a glucoamylase and a debranching transferase. The latter transferred α-1,6-glucosyl units from panose to glucose forming maltose and appeared to have some debranching activity on amylopectin. The α-amylase had the following properties: MW 38000 daltons; no effect of added calcium ions on activity; optimum temperature and pH for activity around 40°C and pH 5.5; ΔH

    Inactivation of active glucose transport in Candida wickerhamii is triggered by exocellular glucose (1985)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 28 (1985), S. 0 
    Details

    Topics: Biology
    Notes: Abstract Under conditions of derepression the yeast Candida wickerhamii formed a high-affinity glucose proton symport. Glucose and glucose analogues induced inactivation of the glucose proton symport and its interconversion into a low-affinity facilitated diffusion system. The specific inactivation rate increased with the concentration of the inactivating sugar and did not obey saturation kinetics. This dependence was still pronounced at sugar concentrations far above saturation of the glucose transport systems. This suggested that the inactivation and interconversion mechanism was triggered by interaction of the inactivating sugar with receptor sites located on the cell surface.

    Yeast diversity in hypersaline habitats (2005)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 244 (2005), S. 0

    ISSN: 1574-6968

    Topics: Biology
    Notes: Thus far it has been considered that hypersaline natural brines which are subjected to extreme solar heating, do not contain non-melanized yeast populations. Nevertheless we have isolated yeasts in eight different salterns worldwide, as well as from the Dead Sea, Enriquillo Lake (Dominican Republic) and the Great Salt Lake (Utah). Among the isolates obtained from hypersaline waters, Pichia guilliermondii, Debaryomyces hansenii, Yarrowia lipolytica and Candida parapsilosis are known contaminants of low water activity food, whereas Rhodosporidium sphaerocarpum, R. babjevae, Rhodotorula laryngis, Trichosporon mucoides, and a new species resembling C. glabrata were not known for their halotolerance and were identified for the first time in hypersaline habitats. Moreover, the ascomycetous yeast Metschnikowia bicuspidata, known to be a parasite of the brine shrimp, was isolated as a free-living form from the Great Salt Lake brine. In water rich in magnesium chloride (bitterns) from the La Trinitat salterns (Spain), two new species provisionally named C. atmosphaerica– like and P. philogaea– like were discovered.

    Transport of fructose by a proton symport in a brewing yeast (1986)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 36 (1986), S. 0 
    Details
    ISSN: 1574-6968
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Abstract Saccharomyces cerevisiae IGC4261, a brewing strain, transported fructose and sorbose but not glucose by a high-affinity, low-capacity proton symport. The symport was not subject to glucose repression and coexisted with the facilitated diffusion system for glucose, fructose, sorbose and other sugars. Transport by the symport was accumulative. The stoichiometry was one proton per molecule of fructose. Maltose acted as a non-competitive inhibitor.

    Alterations of wheat-germ agglutinin binding pattern on cell surface of blood platelets after thrombin stimulation (1989)
    Springer
    Histochemistry and cell biology 91 (1989), S. 461-467 
    Details
    ISSN: 1432-119X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary An attempt was made to demonstrate wheatgerm agglutinin (WGA) binding sites on platelet surfaces after thrombin stimulation, by means of a post-embedding cytochemical technique using colloidal gold as marker at an ultrastructural level. In unstimulated platelets washed with EDTA, an intense uniform labeling of WGA-gold complexes was found on the surface membrane. When washed platelets were stimulated by thrombin in the absence of Ca2+, only a release reaction was induced. WGA labeling on the surface membranes of these platelets decreased dramatically. However, the labeling intensity of WGA-gold complexes on the surface membrane of aggregated platelets induced by thrombin in the presence of Ca2+ increased significantly compared to that of thrombin-stimulated platelets in the absence of Ca2+. In contrast to the uniform labeling on the surface membranes of unstimulated platelets, clusters of gold label were often found on the surface membrane of the aggregated platelets, although there was no significant quantitative difference in the labeling intensity between these two groups. Thus, we present direct morphological evidence demonstrating qualitative and quantitative alterations of WGA labeling on the surface membrane of platelets after thrombin stimulation. The possibility is considered that WGA-binding glycoproteins in the surface membrane are involved in the aggregation response after thrombin stimulation.

    Yields of yeast growth on starch (1977)
    Springer
    Applied microbiology and biotechnology 4 (1977), S. 29-35 
    Details
    ISSN: 1432-0614
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Summary A survey was made of 81 starch-assimilating yeasts, representing 59 species and varieties, with respect to their capacity for the direct conversion of starch into SCP. The extent of starch conversion by the native amylases of the strains during exponential growth, expressed as yield on starch (final amount of dry biomass formed per unit mass of starch originally supplied), varied over a wide range (0.043–0.590) The highest yields were obtained with strains ofLipomyces starkeyi andL. kononenkoae which converted on the average respectively 84% and nearly 100% of the starch supplied. The rate of starch hydrolysis byL. kononenkoae did not limit its specific rate of growth and SCP production.
