(ii)
A given bioreactor supports S. cerevisiae growth with oxygen uptake rates
(OUR) of 0.34 mM h¯¹. Under limiting oxygen conditions, whereby the yeast
culture consumes the oxygen as quickly as it is provided. What must be the
concentration of dissolved oxygen (mM) in the bioreactor to maintain ideal
growth? Assume kLa = 6 h³¹ and given that the partial pressure of O2 is 0.21
atm and Ho₂ = 1.08 atm L-1 mmol¹. Note: Clearly outline your reasoning,
indicating all the steps involved in the calculations and the respective units.
Please, keep two significant figures throughout.
If a researcher seals the flask from part (i), so that oxygen cannot enter, which
compounds will accumulate?
