A genetically-engineered strain of yeast is cultured in a bioreactor at 30⁰C for production of heterologous protein. The oxygen requirement is 80 mmol 1-1 h-I; the critical oxygen concentration is 0.004 mM. The solubility of oxygen in the fermentation broth is estimated to be 10% lower than in water due to solute effects. What mass-transfer coefficient is required if pure oxygen is used instead of air?

Triploids are usually autopolyploids. They arise spontaneously in nature, but they can be constructed by geneticists from the cross of a 4n (tetraploid) and a 2n (diploid). Triploids are characteristically sterile due to
