    (SUARY)

    The kinetics of growth oftwo brewing yeast strains in relation to ergosterol synthesis and glycogen dissimilation after pitching was comparatively investigated.It was established the direct relation between wort oxygen content and new yeast iomass formed from, ergosterol synthesis and glycogen dissimilation. Different kinetic models are synthezed

    Biotechnol. & iotechnol. Eq. 7/1993/3 90

    explained the influence of oxygen ofthe yeastgrowth based the experimental data obtained.
