Protein produced by bacillus subtilis atcc21332 in the presence of cymbopogon flexuosus essential oil
Proteins levels produced by bacteria may be increased in stressful surroundings, such as in the presence of antibiotics. It appears that many antimicrobial agents or antibiotics, when used at low concentrations, have in common the ability to activate or repress gene transcription, which is distinct...
