l know plates are typically inverted but for this yeast and mold exercise we are incubating them at 22 degrees on acidified PDA and they need to be upright... why?

 

Why would you leave plates upright to incubate in microbiology lab

Are you leaving them upright the entire time they are incubating? I'd never grown yeast or mold but you leave bacterial plates upside down to prevent the condensation formed at 37C from dripping onto the plate..
