Dear Mia,
	We use M. smegmatis in our microbiology course for both cultural 
characteristics and to teach acid-fast staining. We have never had to 
vary growing conditions from those of the environment. M. Smegmatis can 
be included as part of the "normal flora" in terms of its growth 
requirements, so try growing it at 37 degrees on TSA or in TSB. For 
further information, consult Bergey's Manual 9th ed. I hope this helps.
