Abstract: ROCHE, ANGELA D. Tolerance to Selected Metals of Bacterial Isolates from Rivers of Cavite. Undergraduate Thesis, Bachelor of Science in Biology, Department of Biological Sciences, College of Arts and Sciences, Cavite State University, Indang Cavite. June 2019. Adviser: Mrs. Jamaica Q. Espineli. This study aimed to determine the percentage of bacterial isolates tolerant to different concentrations (100, 150, 200, 250, 400, and 800 ppm) of selected metals (aluminum, barium, cadmium, chromium, and nickel), analyze the multiple metal tolerance of bacterial isolates and determine the bacterial genus that is most tolerant to selected metals. One hundred fifteen bacterial isolates of Quinones-Espineli and Ilagan (2018) were used in this study. All isolates (100%) were able to tolerate the different concentrations of aluminum, barium and nickel. A decrease in tolerant percentage was observed from 100 ppm to 800 ppm concentration of cadmium. For chromium, all isolates were able to tolerate 100 ppm and 150 ppm concentrations. Escherichia coli was observed to be the most tolerant to aluminum, barium, nickel, and cadmium while Corynebacterium to chromium. The isolates exhibited multiple metal tolerance since they were able to tolerate at least three of the metals used. Fifty-two out of the 1 15 bacterial isolates tested exhibited penta-tolerance with only one tolerant combination, 53 isolates for tetra-tolerance with two different tolerant combinations and 10 isolates for tri-tolerance pattern with one tolerant combination.
