　　The presence ot antibictic resistance mariners are obviously undesirable traits in food production,so it was necessary to construct special food-grade cloning vectors to be used for the expression of recombinant protein.In our study,a new food-grade cloning vector for E.coli and Saccharomyces cerevisiae,was developed using an tt-galactosidase gene (Mell) as a selection marker.
