| Abstract | ||||
| Some fatty acids and other important products can be obtained from potato washing residue stream produced during Chips manufacturing, which hydrolyze by hot acid H2SO4 1% v/v 60 min under semianerobic conditions as economical source by Saccharomyces cerevisiae (y- 1646). Saccharomyces cerevisiae was able to utilize from this residual and production an acceptable amount of fatty acid and other important products. 2, 3 –dihydroxypropyl ester was found in higher levels (568.1 gl-1) and was followed by hexadecanoic acid (221.4 gl-1), and oleic acid (omega 9) 2.1 gl-1 at 35 ºC after 36 h from addition of ZnCl2 (0.4 gl-1). Study recommends intensive investigation in this research point to enhance the production of that extremely important compound. | ||||
