on this compound, H,S is generally produced, and extracellular 
sulphur, the tetrathionate, and also globules of sulphur in the 
hyphae sometimes occur.

and Welde (15), and Raciborski (705), working with bacteria and 
higher fungi, have presented equations representing the possible 
course of the changes involved, the variations in the equations 
depending upon the chief end product. The 3 fungi used have 
produced all of the above-named compounds in one or the other 
of the solutions employed, hence it has seemed inadvisable to give 
a specific equation representing the probable nature of the meta- 
bolic changes.
