Summary
Geotrichum lactis was grown in culture media with different carbon and nitrogen sources. Biotin is needed as a growth factor. During incubation in shake flasks mycelium and arthrospores are produced. Under certain conditions, such as low pH, there is a new form that we have called “yeast-like form”. This thick-walled form develops from mature arthrospores. The arthrospore and the yeastlike cells have walls with different chemical and structural composition, as observed in the electron microscope, and in their resistance to some lytic extracts.
