Effects Of Copper On Oxidative Stress And Growth Of Pseudomonas Putida, Tiffany Marshall
Effects Of Copper On Oxidative Stress And Growth Of Pseudomonas Putida, Tiffany Marshall
Undergraduate Honors Capstone Projects
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, …
The Effect Of The Herbicide Glyphosate On The Growth Of Selenastrum Capricornutum, Judith Susan Eisen
The Effect Of The Herbicide Glyphosate On The Growth Of Selenastrum Capricornutum, Judith Susan Eisen

The herbicide glyphosate (MON-0139), an isopropylamine salt of N- (phosphonemethyl)glycine, was tested to determine its effects on the growth of the fresh water green alga Selenastrum capricornutum. Experiments were carried out to determine algicidal, algistatic, and inhibitory concentrations of the compound.
Concentrations from 5 ppm to 1000 ppm were inhibitory to the growth of the alga, but the effects were algistatic, rather than algicidal. At concentrations from 0.1 ppm to 1.0 ppm the growth of the alga was stimulated by the presence of the herbicide, while at concentrations from 0.001 ppm to 0.05 ppm the effects of the herbicide were …
