Stoichiometric equations are used to represent growth of microorganisms provided a ' molecular formula' for the cells is available. The molecular formula for biomass is obtained by measuring the amounts of C, N, H, O and other elements in cells. For a particular bacterial strain, the molecular formula was determined to be C4.4H7.30 1.2N0.86 . These bacteria are grown under aerobic conditions with hexadecane (C16H34) as substrate. The reaction equation describing growth is:

You have been put in charge of a small fermenter for growing the bacteria and aim to produce 2.5 kg of cells for inoculation of a pilot-scale reactor. What minimum amount of hexadecane substrate must be contained in your culture medium?

Enzyme activity was monitored over the last two stages of an enzyme extraction-separation process. 0.4 g protein, from Stage 5, converted 46 mmol substrate in 10 sec, and 0.02 g protein, from Stage 6, converted 49 mmol in 30 sec. Calculate % increase in activity obtained over the two step

With the help of DNA fingerprinting which can be used to determine paternity. There are three babies (Baby A, Baby B and Baby C) in a maternity ward, and three sets of confused and worried parents. (Father and Mother #1 are a couple, as are Father and Mother #2, and Father and Mother #3.)

You do each PCR reaction and load each one into a separate well of an agarose gel, and then run the gel.

Why is it that some people show two bands?
