Yeasts C. pseudotropicalis are capable to utilize oleate and
ethylamine in the presence of glucose as carbon source. Oleate concentrations
0.5% and 1% with addition of glucose revealed optimal to cells
growth.Concentrations for cells growth of ethylamine – 1% without glucose in
cultivation medium and 0.5% with 1% glucose was optimal. Aminooxidase activity
revealed high in cells cultivated and incubated in growth medium with 0.5%
ethylamine and 1% glucose, when compare with cells, to which ethylamine was
accecible as sole nitrate and carbone source. Appearance of peroxisomes in
C.pseudotropicalis cells during utilization of known inductors of this
microbody biogenesis – oleate and ethylamine, was demonstrared first.
