Upotreba patočnog ulja, nusproizvoda prehrambene industrije u biotehnologiji - Kinetički model enzimske esterifikacije izoamilnog alkohola s oleinskom kiselinom pomoću lipaze B iz plijesni Candida antarctica
Patočno je ulje („fusel oil“) nusproizvod destilacije, a njegov je glavni sastojak izoamilni alkohol čijom esterifikacijom nastaju esteri. U ovom je radu ispitana esterifikacija oleinske kiseline s izoamilnim alkoholom u n-heptanu pomoću lipaze B izolirane iz kvasca Candida antarctica (preparat Novo...
