CRUZATE, GINA LORENA PEREZ and PARRA, MORENA LANDICHO. Isolation and Identification of Bacteria and Fungi from Pharmaceutical Wastewater. Undergraduate Thesis, Bachelor of Science in Biology, major in Microbiology. Cavite State University Indang, Cavite. April 2005 Adviser: Dr. Yolanda A. Ilagan. This study was conducted to characterize wastewater samples, and isolate and identify different bacteria and fungi from wastewater. The samples were taken from wastewater from two pharmaceutical companies, namely EUROMED and BAXTER. These samples exhibited whitish to yellow color with gray or black precipitates. The pH was neutral ranging from 6.96 to 7.01. Direct Euro MEd gave the highest bacterial count while River-BAXTER gave the highest fungal count. It was noted that the pH of the samples did not affect the growth of bacteria and fungi. Bacterial isolates were identified as Micrococcus, Staphylococcus, Streptococcus, Bacillus, Arthrobacter, Kurthia, Brevibacterium, Microbacterium, Cellulomonas, Alcaligenes, Xanthomonas, Acetobacter, Flavobacterium, Escherichia, Shigella and Salmonella. Among these, Micrococcus, Flavobacterium and Xanthomonas were the most predominant being present in most of the samples taken. One Actinomycete was also isolated. Mold isolates belonged to the genera, Penicillium, Cladosporium, Helminthosporium and Aspergillus. Meanwhile, majority of the yeast isolates were identified as Saccharomyces while the rest were Hansenula, Debaryomyces, Torulaspora and Pichia.
