Amylolytic activity of yeast transformants in plate assays. S. cerevisiae JPU and CEN.PK2 were transformed with the indicated plasmids and plated in MD medium supplemented with 1% starch. After 24 h (JPU) and 48 h (CEN.PK2) of growth at 30 °C, the plates were stained with iodine vapor. The different growth time between strains was due to the slower growth rate of CEN.PK2 laboratory strain
