Morphological changes of Torulopsis ethanolitolerans during continuous culture.Peer-reviewed article

J. RYBÁŘOVÁ, J. ŘEŽÁBKOVÁ

The morphological changes of the yeast population Torulopsis ethanolitolerans that were observed during a continuous culture result from changes in oxygen concentrations in the medium. The highest changes were observed under conditions of oxygen limitation. .These changes manifest their self in the cell elongation and the lowering of the cell volume. Eliminating the oxygen limitation the yeast cells obtain their typical form and size in batch cultures. The plot between the morphological changes and the content of nitrogen compounds in the cell biomass was proved.
