Fig. 4From: Use of the kojA promoter, involved in kojic acid biosynthesis, for polyketide production in Aspergillus oryzae: implications for long-term productionImages of the ΔkojA (left) and the ΔkojA_PkojA::wA (right) strains. (a) Image obtained after incubation at 30 °C for 7 days of the CD agar plates where 5 × 105 spores were spread-inoculated. Images of plates taken from the top (upper row) or the bottom (lower row) are shown. (b) Image of the liquid culture after cultivation at 30 °C at 200 rpm for 5 daysBack to article page
