Fig. 1From: Enhanced 2-keto-l-gulonic acid production by applying l-sorbose-tolerant helper strain in the co-culture systemThe effect of l-sorbose on the growth of helper strain. Diamond the OD of helper strain at 0 h of fermentation at different concentration of l-sorbose; square the OD of helper strain at 12 h of fermentation at different concentration of l-sorboseBack to article page
