| Popis: | The purpose of the study was to utilize the waste fish oil after fish smoking process in Y. lipolytica yeast batch cultures in order to assess its valorization to whole-cell biocatalysts with lipolytic properties. Almost 90% of the waste carbon source in medium was used and batch cultures of Y. lipolytica W29 were characterized with biomass yield of 18.59 g/dm3 and lipolytic activity of 53.41 U/g. The yeast biomass was used as a whole-cell biocatalyst in the synthesis of esters of selected phenolic compounds (acetates of 2-phenylethanol, tyrosol (2-(4-hydroxyphenyl) ethanol) and 3-phenyl-1-propanol, and ethyl esters of phenylacetic, 4-hydroxyphenylacetic, 3-phenylpropanoic, and 3-(4-hydroxyphenyl) propanoic acids). Y. lipolytica biomass was able to catalyze esterification of 3-phenylpropanoic acid (conversion of 95% after 24 h), but conversion of other acids to their esters was very weak, and in the case of transesterification of aromatic alcohols with vinyl acetate, conversions were 27%&ndash 63% after 24 h. Synthesized esters were tested prior potential activities as food additives. Esters of hydroxylated phenolic compounds showed activity of 2.5 mg/mL against Klebsiella pneumoniae and Citrobacter freundii, exhibited similar antioxidant properties to their precursors, and were better soluble in lipids, which increases the possibility of their use in the food industry. |
