Environmental factors influence rate of bacterial growth such as acidity (pH), temperature, water activity, macro and micro nutrients, oxygen levels, and toxins. Conditions tend to be relatively consistent between bacteria with the exception of extremophiles. Bacterium have optimal growth conditions under which they thrive, but once outside of those conditions the stress can result in either reduced or stalled growth, dormancy (such as formation spores), or death. Maintaining su… WebBacteria Growth Rate Formula: Nt = N0 * ( 1 + r)t. where: Nt: The amount at time t. N0: The amount at time 0. r: Growth rate. t: Time passed.
