Time-course shift in the A. oryzae wA product YWA1 secreted by the ΔkojA_PkojA::wA strain. The product yield was measured by specific absorbance at 406 nm of the culture supernatant. Absorbance of the culture supernatant at each culture period was subtracted by that of culture medium without inoculation, followed by division by dry cell weight of hyphae. The calculated value was monitored for both the ΔkojA_PkojA::wA strain (red) and the control ΔkojA strain (blue). Error bars represent mean ± standard deviation (n = 3). The result of a significance test (Student’s t-test) between the day 0 and the other date is shown above each bar. * and ** represent p < 0.05 and p < 0.01, respectively
