These and similar results cannot give all the changes that take place 

 even in pure cultures, but only those involving the production of 

 substances that chemists can identify. Again, in nature the conditions 

 are different owing to the presence of different kinds of bacteria on 

 the decomposing material, which cannot but influence not only the 

 amount of, but also the nature of, the decomposition of any one of the 

 competing organisms.
