چکیده
|
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.
