Fig. 4From: Minos and Restless transposon insertion mutagenesis of psychrotrophic fungus for red pigment synthesis adaptive to normal temperatureRed pigment production and cell growth of MPD1–MPD13 mutants obtained by dual transposable systems. a The red pigment production and its dry weight of the mutants at 14 °C. b The red pigment production and its dry weight the mutants at 20 °C. The value of the bar represents the highest pigment level or the highest biomass dry weigh at culture duration. Determination of absorbance value of red pigment at wavelength of 520 nm (OD520). Data of significance were shown in **P < 0.01 and *P < 0.05Back to article page
