Analytical profile indexing was conducted in (CHAT), CLSU Hydroponics, Aquaponics Technologies Demonstration Farm and Experimentation Station, Central Luzon State University, to identify bacteria present in hydroponic production water system using a recirculating prototype module. Water samples were collected from different sampling points, in three collection periods with an interval of 20 days. Environmental factors such as temperature and relative humidity, water quality monitoring parameters like pH, total dissolved solids, water temperature, electrical conductivity and dissolved oxygen were monitored to attain a desirable ecosystem for optimal growth of living organism in the systems. Water samples taken from system of greenhouse hydroponic production were analyzed for total viable bacteria (CFU/ml) in the water. Microbial identification and comparison of bacterial isolates were done using biochemical identification of bacteria based on the methods of API Staph and API Coryne strip. A total of twenty-five (25) bacteria were isolated out of which fifteen (15) strains of microbes have relatively high growth in the medium were identified and described. Eleven (11) bacterial isolates belongs to genus Staphylococcus, namely S. capitis, S. lugdunensis, S. cohnii, S. sciuri, S. auricularis, S. hominis, S. lentus, S. haemolyticus, S. hyicus, S. warneri and, S. caprae one under each genus Corynebacterium, Cellulomonas Leifsonia, and Kocuria were identified and characterized to determine the structure, arrangements, habitat, activity, and pathogenicity of bacteria present in the hydroponic production. The results reveal great diversity of organisms isolated including the presence of pathogenic microorganism, endophytic bacteria (rhizobacter) and commensally occurring bacteria.
