To minimize the possibility of working with a double transductant, use colonies of the plate that used the most diluted P22. While ''int'' P22 cannot form true lysogens, pseudolysogens can occur. We can distinguish phage-cured transducatants from pseudolysognens by streaking on green agar plates. Phage free colonies are light green, while psedolysogens are dark blue-green. | ||
