Production of sulfur flavors by ten strains of Geotrichum candidum.
Ten strains of Geotrichum candidum were studied on a liquid cheese model medium for the production of sulfur compounds which contribute to the aroma of cheeses. The volatile components produced by each cultured strain were extracted by dynamic headspace extractions, separated and quantified by gas chromatography (GC), and identified by GC-mass spectrometry. It was shown that four strains of thi...
متن کاملDisseminated Geotrichum candidum infection.
The pathogenicity of the fungus Geotrichum candidum in humans has not been clearly defined. A patient with acute leukemia who developed a fatal disseminated G. candidum infection while neutropenic is described. At autopsy examination, this patient was misdiagnosed on the basis of histopathology as having disseminated candidiasis until G. candidum was isolated from postmortem culture specimens. ...
متن کاملElucidation of the effects of inoculum size and age on lipase production by Geotrichum candidum
Lipases are extremely versatile enzymes with large industrial applications and they have been the subject of investigation over the last few years. A great variety of microorganisms can produce this enzyme, such as pluricellular fungi, but their growth need to be optimized due to the variations amongst experiments, which influence the results and reproducibility of the process. The aim of this ...
متن کاملFatty acid preference of mycelium-bound lipase from a locally isolated strain of Geotrichum candidum.
Mycelium-bound lipase (MBL) was prepared using a strain of Geotrichum candidum isolated from local soil. At the time of maximum lipase activity (54 h), the mycelia to which the lipase was bound were harvested by filtration and centrifugation. Dry MBL was prepared by lyophilizing the mycelia obtained. The yield of MBL was 3.66 g/l with a protein content of 44.11 mg/g. The lipase activity and spe...
متن کاملDiversity of Geotrichum candidum strains isolated from traditional cheesemaking fabrications in France.
The diversity of French fungus-ripened cheeses is due partly to the succession of fungi that colonize the cheese during ripening. Geotrichum candidum appears in the early stages of ripening on soft cheeses such as Camembert and semihard cheeses such as St. Nectaire and Reblochon. Its lipases and proteases promote flavor development, and its aminopeptidases reduce bitterness imparted by low-mole...
