Question

What is the yield coefficient if the initial substrate concentration is 20 g/l and biomass is 0.2 g/l. The substrate is then consumed and produces 6.0 g/l of biomass?

(a) 0.09 g biomass / g substrate

(b) 0.19 g biomass / g substrate

(c) 0.20 g biomass / g substrate

(d) 0.29 g biomass / g substrate

The question was asked in homework.

My doubt is from Yields in Cell Culture topic in division Homogenous Reactions of Bioprocess Engineering

Answer 1

The correct choice is (d) 0.29 g biomass / g substrate

Best explanation: Yield = (6.0 – 0.2 g biomass) / (20 g substrate) = 0.29 g biomass / g substrate.
