Abstract:Invertase liberation from Saccharomyces cerevisiae was detected after application of series of rectangular millisecond electric pulses. Maximal yield (60% from the activity in crude extract) was achieved within 8 h after pulsation. As shown by staining SDS-PAGE for invertase activity, the main part of liberated enzyme is a high molecular weight periplasmic invertase.
Keywords:electropulsation  extraction  invertase  Saccharomyces cerevisiae
