The rates of reactions (5-18), (5-25), (5-11) and (5-50) are ν 1 to ν 4 , and can be
expressed by the rate vector ν r :

By writing out the compound balances for each of the eight compounds (benzyl
alcohol, toluene, biomass, ammonia, oxygen, carbon dioxide, ATP and NADH 2 ), the
following nine linear relations are obtained:

r θ ⋅ν
+ φ
(5-52)
= bt
where φ r is the vector of flow, and r r is the vector of the overall conversion rates of the
compounds.
For continuous operation at steady state, r = 0 , thus the following equations can
be obtained from Equation (5-52):
