The way the authors calculate the Quantum yield is by dividing estimated total number of electrons to estimated total number of photons. If you do it the way the plant and algae people do it(divide the total number of carbon to the total number of photons), the quantum yield of photosynthesis is now 20% (in plants and algae you can get to 10-11%).
Also, cysteine is used as a reductant - as soon as they will try to use water as an electron donor the efficiencies will like ly to go down.
And who is going to count the energy needed for bacteria metabolism?!
