Q3

In this problem, assume that microbial net growth efficiency is 40%

1. How many new microbial cells can be produced from this substrate?

2. How many atoms of C and N(in total) are found in the new microbial cells? # C and # N

3. How many molecules of Carbon dioxide are produced in total?

4. How many atoms of C and N are found in the residue

5. If you applied coffee grounds (50 C, 2 N; C:N 25:1) to the residue, how many additional microbial cells would be produced?

6. How many additional molecules of carbon dioxide would be produced?
