Abstract: MATIENZO, REYZHEL A., SUNER, GAIA-FATE R., and URIAS, HAZEL JANE C., Use of Different Extraction Solvents for Antibacterial Compounds from Red Algae (Rhodophyta) Research Study (General Science Curriculum) Science High School, College of Education, Cavite Stale University. Indang, Cavite. May 2018. Adviser: Dr. Hosea L. Matel. The study was conducted to determine the most effective solvent for the extraction of antibacterial compound from red algae. Three solvents were used in the study, namely methanol, ethyl acetate, and hexane. The inhibitory activity of the different extract were tested against two gram-positive and one gram-negative bacteria using agar-well assay. The diameter zone of inhibition exhibited the extract was measured. Chloramphenicol was used as positive control. The methanol and ethyl acetate extracts inhibited the growth of both gram-positive bacteria while none of the extracts inhibited the gram-negative bacterium. The pure solvents showed no antibacterial properties in all the bacteria that was used. The gathered data and statistical analysis showed that the most effective extracting solvent is methanol since it has the largest diameter of zone of inhibition among the other extracts in both gram-positive bacteria 1 and 2.
