Bacterial growth refers to the increase in the number of bacterial cells in a population, achieved characteristically through binary fission, in which a cell replicates its genome and divides into two daughter cells. In a closed culture, population growth follows a reproducible bacterial growth curve comprising distinct phases: a lag phase of metabolic adjustment, an exponential or logarithmic phase of maximal balanced division, a stationary phase in which nutrient depletion and waste accumulation halt net increase, and a death phase of declining viability. The rate and extent of growth are governed by physical and chemical factors including nutrient availability, temperature, pH, oxygen tension, osmotic conditions, and water activity, parameters that define the niches in which particular organisms can proliferate. Growth is quantified by methods such as viable counts, turbidity measurement, and direct enumeration. The concept is central across microbiology. In clinical settings it underlies infection, intestinal overgrowth syndromes, and the antimicrobial susceptibility testing that depends on inhibiting or killing growing cells. In applied and environmental microbiology, controlled bacterial growth enables biodegradation and bioremediation of pollutants, biosorption of contaminants, and the microbial production of valuable compounds, while unwanted growth is the basis of spoilage and the food and water safety concerns that drive preservation and hygiene practice.
