Bacterial growth is asexual reproduction, or the division of cells from a bacterium into two similar cells in a process called bisection. Without any mutations, the resulting daughter cells are genetically identical to the original cell. From here, the multiplication of bacteria begins, each of the daughter cells of the division does not necessarily survive, however if the number of live bacteria exceeds the average limit, the live bacteria undergo what is called accelerated growth. The calculation of the accelerated growth rate of bacteria is part of the training of all microbiologists, the main method that requires the counting of bacterial growth (counting cells) directly by (flow cytometry - microscopy) [1] or indirectly (counting colonies of bacteria)
