Calculate the specific growth rate (µ) of the population above growing at a substrateconcentration of 25 mg/L according to Monod kinetics with a ks of 50 mg/L.c. Consider two genetically engineered organisms intended for use in the cleanup of hydrocarbonspills into the ocean. Bacterium alpha has a µmax of 1 d'¹ and a ks of 0.1 mg/L. Bacterium beta hasa μmax of 5 d ¹ and a k, of 5 mg/L. If the hydrocarbon concentration is initially 1000 mg/L and thedesired objective is to reduce concentrations below 0.1 mg/L what order of addition of the bacterialspecies is desired?35045
