M-Concentration

M-concentration is the maximum possible number of viable bacterial cells per unit volume of a liquid medium, naturally achieved in the stationary phase of population development under certain cultivation conditions.

M-concentration characterizes the maximum bacterial population density that can be achieved in a given environment under optimal conditions. It depends on the composition of the nutrient medium, aeration, temperature and other factors.

Reaching the maximum cell concentration indicates that the population has entered the stationary phase of growth. In this phase, the rates of growth and death of bacteria balance each other, and the population size stabilizes at some level. Knowing the m-concentration is important for determining the optimal conditions for cultivating bacteria and monitoring their growth.

M-concentration (from the English “maximum concentration”) is the maximum possible number of vital bacterial cells that can be present in a unit volume of liquid in the stationary (constant) phase of development of the bacterial population. It is determined by the bacterial cultivation conditions and may vary depending on the type of bacteria, the culture media used and other factors.

During the cultivation of bacteria, they grow and multiply, which leads to an increase in the number of cells in the population. When the population reaches its maximum concentration, further increase in the number of cells becomes impossible, since the environment can no longer contain so many cells without compromising their growth and development.

To determine the M concentration of bacteria, it is necessary to conduct an experiment in which the number of cells in the liquid is measured at different points in time. This is usually done using microscopy or other methods. The measurement data is then used to plot the growth of the bacterial population over time.

The M-concentration value depends on many factors, including the type of bacteria, the nutrient substrate used, temperature and other cultivation conditions. For example, for some types of bacteria, the M concentration can reach several tens of millions of cells per milliliter of liquid.

M-concentration of bacteria can be used to determine the optimal concentration of bacteria for various processes such as antibiotic production, food fermentation, wastewater treatment, etc. It can also be useful for assessing the effectiveness of bacterial purification and quality control in the food industry.
