The fluorescent soil bacterium Pseudomonas putida is an aggressive root colonizer (1) that offers benefits to the host plant by suppressing soilborne pathogens and enhancing plant growth (12,13). Upon introduction in the field through seed inoculation, certain isolates of P. putida have the potential to act as an effective biological control agent (3). P. putida has also been shown to promote the growth of potatoes, sugarbeets, and radishes (13). Fluorescent pseudomonads are effective in protecting plants against pathogens such as Gaeumannomyces graminis var. tritici, a fungus that causes the root disease of wheat called take-all (13).

Oxygen is an essential compound in all aerobic systems; however, it can also take part in toxic reactions involving active oxygen species (AOS) and transition metals. Most of the time, antioxidant enzymes act as defense mechanisms and keep the production of AOS to a minimum. However, if the defense mechanisms are not adequate, damage may occur and possibly lead to the breakdown of biomolecules such as DNA, lipids, and proteins that are vital to both simple and complex organisms. Oxidative damage could also be a contributing factor to many human pathological conditions including, aging, atherosclerosis, carcinogenesis, diabetes mellitus, lung cancer, …
