[Oxygen consumption by the yeast-like and filamentous forms of Sporothrix schenckii as measured by polarography].
The study of the oxygen uptake by cultures of Sporothrix schenckii as measured with the Clark electrode has shown that when the fungus was grown in a liquid medium, the atmospheric oxygen went into solution very slowly even when the liquid was rapidly stirred. The partial oxygen pressure was very small after some days of culture (no more than 2 or 3% expressed as the saturated value). Hence, it is postulated that the linear part of the growth curve is due to the dissolved oxygen acting as a limiting factor. When the oxygen uptake by filaments, conidia, or yeasts isplotted against the time the curve variations follow the transformations of the fungus.
