These substances are called fungicides.
Antibiotics.

Yes, penicillin prevents the formation of new bacterial cell wall. If a bacteria reproduces, new cell wall cannot be produced and the cell lyses and dies. However penicillin has no effect on a quiescent (non-reproducing) bacteria. Therefore penicillin is also called a bacteriostatic agent (prevents growth of bacteria), which means penicillin does stop bacteria from reproducing.
Allelopathy in plants gives the organism a competitive advantage because the toxic chemical produced prevents other plants growing nearby and eliminates the competition for light, space, water, and nutrients in the soil.
2. The bacteria may release a substance that prevents mold growth.
When the meat is packed in salt it will last longer because the salt prevents the meat from growing bacteria or mold and spoiling. The meat will last for a year or so.

Auxin hormone
The ion nitrate used in curing is converted to nitrite by enzymes or bacteria. The nitrite then prevents the bacteria from growing.

The lactic acid is generally produced by members of the genus lactobacillus. These bacteria are generally harmless to humans. The acidic environment they create, however, harms other bacteria and prevents these potentially dangerous bacteria from growing. So, overall, the food that's being preserved will have predominantly only one type of bacteria in it, which is not harmful to humans.

A container that has growing bacteria must be closed and/or sealed to prevent contamination by other bacteria.
The higher alcohol provided by the blending of brandy and wine prevents the bacteria acetobacter from growing and producing acetic acid which is the key compound in vinegar.
