WebGramicidin S is an anttiboitics. Gramicidin S reduces the cell number of planktonic cells within 20-40 min at a concentration of 40-80 μg/mL. Gramicidin S kills the cells of pre-grown biofilms at concentrations of 100-200 μg/mL, such that no re-growth is possible.

Nonribosomally synthesized peptides e.g., bacitracins, gramicidins, and polymyxins are produced predominantly by bacteria and have a narrow spectrum of activity. Many of these antibiotics were superseded in the 1970s as other new classes of antibiotics ...

Gramicidin S or Gramicidin Soviet is an antibiotic that is effective against some gram-positive and gram-negative bacteria as well as some fungi. It is a derivative of gramicidin, produced by the gram-positive bacterium Brevibacillus brevis.
