Figure 5From: Breeding of a new wastewater treatment yeast by genetic engineering PCR test. (A) Specificity of PCR test for HF-AAMY cells. M, marker The strains are: (1) S. cerevisiae YPH-499, (2) Cryptococcus sp. S-2, (3) H. fabianii J640 (host strain), (4) HF-AAMY (transformant). (B) Sensitivity of PCR test. The number of cells in the reaction mixture are shown at the tops of the lanes.Back to article page
