Pejin, D.J. | Vasic, V.M.(Faculty of Technology, Novi Sad (Serbia and Montenegro))
Saccharomyces cerevisiae is exposed to different stress factors during the production: osmotic, temperature, oxidative. The response to the stress is the adaptive mechanism of cells. The raw materials Saccharomyces cerevisiae is produced from, contain metabolism products of present microorganisms and protective agents used during the growth of sugar beet, for example the influence of acetic and butyric acid and organochlorinated insecticides, lindan and heptachlor, on the metabolism of Saccharomyces cerevisiae was investigated and presented in this paper. The mentioned compounds affect negatively the specific growth rate, yield, content of proteins, phosphorus, total ribonucleic acids. These compounds influence the increase of trechalose and glycogen content in the Saccharomyces cerevisiae cells.
