Abstract

Comparative study of yeast growth and morphology of cells in nitrogen containing medium and under nitrogen starvation conditions has not been done before. The aim of this study was to investigate the ultrastructural changes in yeasts C. guilliermondii NP-4 cultivated with and without nitrogen. The yeast biomass cultivated under nitrogen starvation conditions has been twice lower, than in case of growth in nitrogen containing medium. Ultrastructural analysis of cells, carried out with scanning electron microscope, showed morphological changes in cells. A negative correlation of biomass and cell size was observed.
