文摘

Two chemically defined media, CDM-1G and CDM-1X, that use glucose and xylose as carbon sources, respectively, were prepared for Lactococcus lactis strain IO-1. The maximal cell density at 600?nm in CDM-1G exceeded 2. Omission growth experiments indicated that IO-1 is auxotrophic for 2 vitamins and 6 amino acids.
