Summary. 
from these two experiments 
that for mycelium 
fungi asparagine is a superior source of nitrogen, even far superior 
to such a closely related compound as ammonium succinate. 
Protein-production must then be much more easily possible from 
the former than from the latter, i.e., the way from asparagine to 
proteid is much shorter than that from ammonium succinate al¬ 
though this is so closely related to asparagine. This conclusion 
holds good also for phænogams as shown above.
