RESUMO
The influence of the genetic background of Cymbopogon species on the antifungal activity of essential oils derived from the plants was investigated against three yeast-like and nine filamentous fungi. Essential oils from distinct strains of the aromatic grass Cymbopogon showed interspecific and intraspecific differences in antifungal activity.

Five aromatic constituents of essential oils (cineole, citral, geraniol, linalool and menthol) were tested for antimicrobial activity against eighteen bacteria (including Gram-positive cocci and rods, and Gram-negative rods) and twelve fungi (three yeast-like and nine filamentous). In terms of antibacterial activity linalool was the most effective and inhibited seventeen bacteria, followed by cineole, geraniol (each of which inhibited sixteen bacteria), menthol and citral aromatic compounds, which inhibited fifteen and fourteen bacteria, respectively. Against fungi the citral and geraniol oils were the most effective (inhibiting all twelve fungi), followed by linalool (inhibiting ten fungi), cineole and menthol (each of which inhibited seven fungi) compounds.

The influence of the genetic background of a plant on the antibacterial activity of essential oil derived from it was investigated. Essential oils from six distinct strains of Cymbopogon were tested against eighteen bacteria. Interspecific and intra-specific differences were evident in the antibacterial activity of the essential oils derived from the the six Cymbopogon strains.
