Step 1: Classify bacterial shapes.
Bacteria are classified based on their shapes: Bacilli: Rod-shaped bacteria. Cocci: Spherical bacteria. Spirilla: Spiral-shaped bacteria. Diplococci: Pairs of spherical bacteria.
Step 2: Match with the question. The question specifies "rod-shaped bacterial cells," which corresponds to Bacilli.
A 2 L bioreactor is being operated as a chemostat, at a flow rate of 0.8 L/h and sterile feed of 10 g/L substrate. The bacterial growth follows Monod kinetics at a maximum specific growth rate of 0.6 h\(^{-1}\) with a Monod constant of 0.5 g/L and a biomass yield coefficient of 0.4 g/g. The exit biomass concentration is _________ g/L. (Round off to one decimal place)
Length of the streets, in km, are shown on the network. The minimum distance travelled by the sweeping machine for completing the job of sweeping all the streets is ________ km. (rounded off to nearest integer)
