- Why may some bacteria use extracellular enzymes to form blood clots? View Available Hint(s) for Part H The blood clots are a necessary food source for the bacteria. Blood clot can hide bacteria from the immune system. A blood clot leads to tissue necrosis or death, a necessary condition for infection. The blood clots cause disease, which is the intended purpose of the bacteria.E. coli can grow at a higher temperature in a complex mediumthan in a defined medium. Why?Are natural compounds such as cellulose and petroleum oil easier for microorganisms (eg. bacteria etc.) to degrade than man-made compounds such as plastics?
