Complete Genome Sequences of the Xylose-Fermenting Candida intermedia Strains CBS 141442 and PYCC 4715

“…The yeast Candida intermedia is known for its capacity to grow on and ferment xylose (2–4). We have sequenced the genomes of two strains of this yeast: CBS 141442, isolated from the liquid fraction of a steam-pretreated wheat straw hydrolysate in Gothenburg, Sweden, and PYCC 4715, isolated from sewage in Oeiras, Portugal, and which has been characterized previously in terms of xylose growth and transport capacity (2, 5).…”

A history of research on yeasts 12: medical yeasts part 1, Candida albicans

“…( Monilia ) krusei , using as criteria: (a) the appearance of the cells grown under differing conditions; (b) fermentation reactions; (c) serological behaviour; and (d) pathogenicity for rabbits25, 26. By such methods, in the years just before World War II, Benham, Maurice Langeron, Raffaele Ciferri and their colleagues56, 145, 147 did much to characterize strains of C. albicans and distinguish them from similar yeasts. This work and that reported in numerous other papers were well summarized by Juan Mackinnon 33 161 and Charles Skinner247.…”

“…In 1938, Maurice Langeron and Paul Guerra described the ability to form chlamydospores as a distinctive feature (‘ absolument caractéristique ’) of Candida albicans (145 p. 431). Working in a hospital in New York in 1957, Taschdjian held that the formation of chlamydospores was ‘the main criterion for rapid identification of C. albicans ’ (263 p. 332).…”

“…23 23 Christine Marie Berkhout (1893–1932), Dutch mycologist, who described the genus Candida in her doctoral thesis for the University of Utrecht in 1923. Her description was later described as marking ‘the beginning of the rational systematics of the anascosporogenous yeasts’ (145 p. 40). She suffered ill‐health from the time she was working on her thesis and seems to have occupied no other post (253 p. 196). …”

A history of research on yeasts 4: cytology part I, 1890–1950

“…Langeron and Guerra's assertion in 1938 that filamentous growth of ‘ Candida lodderi ’ is accentuated in high concentrations of carbon dioxide (129 p. 61) is consistent with the above findings; that is, filament formation is often associated with anaerobiosis and fermentation which produces ethanol and fusel oils. Writing in 1952 on Candida albicans , McClary concludes:

…︁ that where conditions are favourable for rapid multiplication, as with easily assimilable carbohydrates and with abundant aeration, the unicellular yeast forms predominate.
