With the use of sketch, briefly explain the kinetic patterns of growth and product formation in batch fermentation.Two microorganisms that use naphthalene as a food source have the same Umax but different Ks values for naphthalene. If both types of microorganisms are inoculated at the same cell density into a liquid culture containing naphthalene as the sole carbon source (i.e. the only food source), which microorganism will outcompete the other: the one with the higher Ks or the one with the lower Ks. Why?.
