Description

Genetically modified C. acetobutylicum can be anaerobically grown on glucose using ammonia as a nitrogen source to produce mainly butanol (𝐶4𝐻9𝑂𝐻). The biomass can be represented by 𝐶𝐻1.8𝑂0.5𝑁0.2. It has been reported that 0.569𝐶-mole of butanol and 0.14C-mole of biomass are produced by the consumption of 1𝐶-mole of glucose and 0.028 mole of ammonia. -𝛥𝑐-𝐺=39.19𝑘mol for ammonia. For others (glucose, butanol and biomass) 𝛥𝑐𝐺 can be calculated using the relationship, 𝛥𝑐𝐺=112𝜉. Is the second law of thermodynamics satisfied? Justify your answer.
