    Notes: Abstract The obligately fermentative aerotolerant bacterium Zymomonas mobilis was shown to possess oxidative phosphorylation activity. Increased intracellular ATP levels were observed in aerated starved cell suspension in the presence of ethanol or acetaldehyde. Ethanolconsuming Z. mobilis generated a transmembrane pH gradient. ATP synthesis in starved Z. mobilis cells could be induced by external medium acidification of 3.5–4.0 pH units. Membrane vesicles of Z. mobilis coupled ATP synthesis to NADH oxidation. ATP synthesis was sensitive to the protonophoric uncoupler CCCP both in starved cells and in membrane vesicles. The H+-ATPase inhibitor DCCD was shown to inhibit the NADH-coupled ATP synthesis in membrane vesicles. The physiological role of oxidative phosphorylation in this obligately fermentative bacterium is discussed.

    DNA relatedness, karyotyping and gene probing of Candida tropicalis, Candida albicans and its synonyms Candida stellatoidea and Candida Claussenii (1992)
    Springer
    European journal of epidemiology 8 (1992), S. 444-451 
    Details
    ISSN: 1573-7284
    Keywords: Karyotyping ; Candida albicans ; Candida tropicalis ; Candida stellatoidea ; Candida claussenii

    Notes: Abstract Isolates of Candida albicans with varied phenotypes, including sucrose-negative variants (C. stellatoidea, serotypes A and B) and avirulent germ tube-negative forms (C. claussenii) showed significant (〉 90%) DNA relatedness to classical C. albicans, but insignificant relatedness to C. tropicalis and sucrose-negative C. tropicalis. A transverse alternating-field gel electrophoresis procedure (TAFE) showed discrete karyotype patterns among the phenotypic variants of C. albicans including the sucrose-negative C. stellatoidea. The number of chromosome-sized DNA bands for C. tropicalis (7 bands) were within the range of bands observed for C. albicans (5 to 10 bands). The general DNA-migration pattern for C. albicans appeared distinct from that of C. tropicalis. An aspartyl proteinase (PrA) gene probe from C. albicans hybridized with chromosomal DNA from C. albicans, C. claussenii and C. stellatoidea but not with that from C. tropicalis.
