title: [Analysis of oxygen transfer in bioreactors for fungus broths. 2. Suspensions of P. chrysogenum mycelial associations].
abstract: Unlike the P. shermanii and S. cerevisiae cultures, the study on the distribution of oxygen transfer in stirred bioreactor for P. chrysogenum pellets broths indicated that this process is controlled mainly by the deposition tendency of the biomass. Similar to the previously studied systems, the analysis of k(1)a distribution indicated its heterogeneity on the bioreactor height, the oxygen transfer rate increasing from position 1 to 4. Contrary to the bacterial and yeasts cultures, the intensification of aeration promoted the initial reduction of k(1)a, which reached a minimum level, followed by its increase, due to the flooding phenomenon.
