Yeasts

Delivered with
50 petri dishes with sterile dehydrated culture media on a cardboard support
50 black grid membranes with diameter 50 mm and porosity 0.6 μm

Incubation
2 to 3 days at 25°C

Growth
Yeasts form white to cream-coloured, occasionally also reddish colonies.
The colonies of moulds are initially white with clearly visible aerial mycelium (velvety) and become coloured when forming conidia.
The low pH-value of the medium inhibits the growth of most bacteria.
