Yeast culture, a laboratory approach

Dear brewmates… Im conducting some lab experiments trying to culture beer yeast for homebrew (of course… as close to GLP as possible) …

*any advice about conditions?
*Media culture?
*Cell Count?
*Cell/Pitch Formulation?

Thanks in advance.
Greetings from Argentina.
