Abstract

Through a small desktop automatic fermentor bio-transformation test,the pH,dissolved oxygen and other parameters which affect the production of 2-phenylethanol(2-PE) were studied.The results showed that the initial pH5.5 of medium was suited and not need to be further controlled,and dissolved oxygen was taken different actions during different phase;batches up the sugar could promote the growth of S.cerevisiae CWY132 and greatly increase the production of 2-PE.Under the optimum culture conditions,the production of 2-PE reached 4.1 g/L,the molar conversion rate of L-phenylalanine to 2-PE rises to 79.43%.

Key words： Saccharomyces cerevisiae; 2-phenylethanol; biotransformation process; small fermentor
