Penicillin is produced by P. chrysogenum in a fed-batch culture with the intermittent addition of glucose solution to the culture medium. The initial culture volume at quasi-steady state is V₀ = 500 l, and glucose-containing nutrient solution is added with a flow rate of F = 50 l/h. Glucose concentration in the feed solution and initial cell concentration are S₀ = 300 g/l and X₀ = 20 g/l, respectively. The kinetic and yield coefficients of the organism are mm = 0.2 h^-1 , K_S = 0.5 g/l, and Y_X/S = 0.3 g dw/g glucose. Determine the culture volume at t = 10 h

The rate of photosynthesis when red and far-red light are given together is greater than the sum of the rates when they are given apart, the effect provided essential

evidence in favor of the concept that photosynthesis is carried out by two photochemical systems working in tandem but with slightly different wavelength optima

this effect is known as
