Of cells rather than in size of individual cells •the requirements for microbial growth can be divided into two main categories: physical and nutritional factors affecting microbial growth physical factors •ph •temperature •osmotic pressure •hydrostatic pressure •moisture •radiation •oxygen concentration nutritional factors •carbon •nitrogen.
Investigating electrochemical cells background an electrochemical cell makes use of a redox reaction and uses the chemical reaction to produce an electric current different chemical systems can be set up to produce different electrochemical cells and o ne way of comparing the cells is to measure the voltage that they generate once a particular cell has been set up there are various factors. Physical and chemical factors affecting microbial growth thermophiles thermophiles are adapted to temperatures above 60 degrees in a variety of ways often thermophiles have a high g + c content in their dna such that the melting point of the dna (the temperature at which the strands of the double helix separate) is at least as.
