(microbiology)

Inhibition of bacterial growth and metabolism.

Bacteriostasis

complete inhibition of growth and propagation of bacteria; caused by unfavorable physical or chemical factors or by the absence of necessary conditions for their growth (moisture, temperature, pH of the medium, and so on). In these circumstances the metabolic processes of microbial cells are disrupted. When the effect of bacteriostatic factors ceases, growth and propagation of bacterial cells are resumed; if their effect is prolonged, the bacteria are destroyed. During bacteriostasis bacterial cultures usually lose their viability and stop producing toxic substances. The beneficial effect of chemotherapeutic medications used in both human and veterinary medicine is based on this phenomenon. Bacteriostasis may be caused by a great variety of bacteriostatic substances. Among the physical factors that cause bacteriostasis are radiation, low temperatures, and high osmotic pressure.

Acetic acid has been shown to penetrate into the bacterial cytoplasm resulting in a reduced internal bacterial pH and collapse the electrochemical proton gradient, leading a bacteriostasis and death of susceptible bacteria such as cecal coliforms [39].

suggested that the bacteriostasis could be equated with a loss of the cell's ability to synthesize ATP, which, in turn, may stem from an uncoupling of oxidative phosphorylation [23].

Probiotics can protect organisms via various mechanisms, including bacteriostasis, which plays the most important role in the determination of the dominant bacterial communities within intestinal ecological systems (Tulumoglu et al., 2013).

Bacteria that accumulate in a variety of tissues are subsequently eliminated, although their rates of accumulation, conversion to non-culturable status (bacteriostasis), and degradation differ as a function of the crustacean host, the bacterial pathogen, and the tissue examined.
