196ΔcadAΔldcCΔfadR/pCABD2 strain was cultured at 37° C. for 20 hours on the LB agar medium containing 20 mg/L of streptomycin sulfate. The cells on the agar medium were scraped, inoculated into 4 mL of an L-lysine production medium containing 20 mg/L of streptomycin sulfate contained in a large diameter test tube, and cultured at a culture temperature of 37° C. for 24 hours. For the main culture, the saccharified solution of Example 4 (1) prepared from starches produced by Chlorella kessleri (1.33 g/L in terms of glucose amount), and the hydrolysis reaction mixture of Example 4 (1) prepared from starches and fat or oil were used as carbon sources. As a control, the culture was performed in a medium containing glucose at the same concentration as a carbon source.
