FIG. 1.
Specific chitinase (chi), β-1,3-glucanase (glu), and protease (pro) activities in L. enzymogenes culture filtrates from strain C3 or 5E4 cultures grown in minimal salts medium 813 supplemented with yeast cell walls. The activity values were standardized to 109 CFU, and the data are the means and standard deviations for three replicates. Below the graphs enzyme activity is shown as zones around colonies grown on medium 813 agar supplemented with 2% colloidal chitin (chi), 0.5% laminarin (glu), or 1% skim milk (pro).
