Screening method and strains to produce more alternan than dextran |
摘要 |
A rapid screening procedure to select microorganism strains that produce a high proportion of alternan to dextran and a high proportion of alternansucrase to dextransucrase is described. Strains selected by the method are useful to produce a high proportion of alternansucrase to dextransucrase and to produce a high proportion of alternan to dextran, either fermentatively by cultivation of the strains on sucrose, or enzymatically by using alternansucrase produced by the strains of the invention. The selected strains can also be used to obtain microorganism strains having further improvements. |
