Figure 3From: Heterologous expression of a tannic acid-inducible laccase3 of Cryphonectria parasitica in Saccharomyces cerevisiaePlate assay using tannic acid-supplemented media. Dark brown staining was observed around colonies of transformants, whereas no color reaction was observed around a colony of a mock transformant. 1, 2, 3, and 4 represent the mock transformant, TYEGLAC3-1, TYEGLAC3-5, and TYEGLAC3-7, respectively.Back to article page
