Filed: 1988-10-26
Abstract: PURPOSE:To eliminate production of urea in wines or alcohols by making a brewing using Saccharomyces cerevisiae transformed by a plasmid vector for alginase gene destruction of a plasmid vector for alginase gene replacement. CONSTITUTION:A plasmid vector for alginase gene destruction or a plasmid vector for alginase gene replacement is cut with a restriction enzyme into straight chain DNA.
