Congo Red Decolorization By Two Bacterial Isolates From Cal-Sag Channel Under Static Incubation And Intermittent Aeration, Daphne Domingo, Timothy Gsell Apr 2025

Congo Red Decolorization By Two Bacterial Isolates From Cal-Sag Channel Under Static Incubation And Intermittent Aeration, Daphne Domingo, Timothy Gsell

Research Days

This study investigated the decolorization of Congo Red, an azo dye, by two bacterial isolates (CS-1 and CS-2) from the Cal-Sag Channel under static incubation and intermittent aeration. The objective was to evaluate whether intermittent aeration enhances decolorization efficiency with the hypothesis that intermittent aeration would enhance decolorization activity by promoting sequential microaerophilic-aerobic condition. This sequential treatment was hypothesized to prevent the accumulation of toxic byproducts of azo dye biodegradation, thus promoting growth and continued decolorization activity by the bacteria. Results showed that CS-1 was the most effective at reducing dye concentration, with no significant impact of intermittent aeration on …

Political Philosophers Shaping Modern America, Sean O'Brien Apr 2025

Political Philosophers Shaping Modern America, Sean O'Brien

Research Days

The research finds that John Locke and his contractarianist philosophies have been more influential in shaping the 21st-century America of today. John Stuart Mill’s philosophies of liberalism have not come to fruition throughout history as much as Locke's. Mill believes at the time of his work, liberalism is a political ideology that happens to be more utilitarian. Over time, America has changed to believe in liberalism, which does not draw as much inspiration from his work. It is his utilitarian philosophy that would reject 21st-century America and the way that it has formed over time. He simply believes in fundamental …
