Abstract
Bacterial contamination of a fungicide was assayed and confirmed through the repetitive isolation and consistent presence of the microorganisms. Identities of the contaminants were necessary to provide a preliminary evaluation of the probable consequence in the usage of a fungicide in the field. Two bacterial isolate SW and PY were obtained. Hypersensitivity test in tobacco was performed to rule out the possibility that these bacteria were phytopathogens. The bacterial isolates labeled SW and PY were studied based on morphological, cultural, physiological and biochemical characters. Isolate SW is gram positive, short to long rods, non spore forming, facultative anaerobe, non-motile, grows in saline condition and have high fermentative ability. While isolate PY is gram negative, short rods, strict aerobe, motile and produce fluorescent pigments. Isolate SW is tentatively identified as Lactobacillus fermentum while isolate PY is Pseudomonas aeruginosa.
