The growth rate of Escherichia coli, a common bacterium found in the human intestine
Growth of Bacteria The growth rate of Escherichia coli, a common bacterium found in the human intestine, is proportional to its size. Under ideal laboratory conditions, when this bacterium is grown in a nutrient broth medium, the number of cells in a culture doubles approximately every 20 min. (a) If the initial population is 20, determine the function Q(t) that expresses the growth of the number of cells of this bacterium as a function of time t (in minutes). (b) How long would...

A group of researchers have been trying to generate a degradable scaffold made of polycaprolactone (PCL) for non-load bearing bone substitute. A literature survey indicates that the scaffold for bone tissue engineering should ideally be at least 80% porous with an average pore diameter of 150-220 μm. 4. (a)Discuss the importance of porosity and pore size in tissue engineering scaffolds. (5 marks) (b) The group finally developed a cylindrical scaffold (12 mm in diameter and 10 mm in height) with...
