Metabolic macromolecules


The microorganism, biocatalyst to all cellular bioprocesses, grows to suit its own purposes: to survive and to prosper. To do this, the microorganism brings about biochemical change by metabolising nutrients to generate energy and/or precursors, and to synthesise cellular components. Biochemical changes take place in a series of intermediate steps, each catalysed by a specific enzyme, and are referred to as the metabolic pathways or the metabolism of the microorganism.In the bioprocess, however, the needs of the microorganism to live and reproduce are replaced by the drive to enhance product formation. Process conditions are manipulated so that the microorganism is exploited to overproduce the desired product ...
