Global emergence of Pseudomonas fluorescens (P. fluorescens) displays a mechanism of resistance to all existing antimicrobials. Morpho-cultural and biochemical identification of Pseudomonas sp. Sagar Aryal. Reply. These microbes produce secondary metabolites that suppress plant disease and signal gene expression to neighboring cells inhabiting the rhizosphere. Nadia Aslam. The sample used for identification of Pseudomonas fluorescens and characterisation based on biochemical characteristics. A glycerol fermentation test was done next to narrow it down further and due to the results of these tests, the second unknown bacterium was determined to be Pseudomonas aeruginosa. The objective of this experiment was to identify P. fluorescens using different biochemical tests. Accordingto some(2, 5, 19), but not all (13), tabulations, degradation ofgelatin is a definitive test for distinguishing Pseudomonasfluorescens (all strains are positive) and P. putida (all strains are negative). This lesson will discuss characteristics of the bacterium species, Pseudomonas fluorescens, including morphology and Gram stain, which aid in the identification of specific bacterial species. May 24, 2018 at 10:03 PM . species. Different biochemical test viz, Catalase test, Starch hydrolysis, Triple sugar iron agar (TSIA), Indole production, ... promoting potential of selected Pseudomonas fluorescens isolates. Objective of this study was to investigate the effect of biofield treatment on antimicrobial sensitivity pattern of P. fluorescens. : P. fluorescens is a bacterial species of the genus Pseudomonas, and it is a plant growth promoting bacterium. This research was carried out in Plant Pathology Laboratory at Agriculture and Forestry University (AFU), Rampur, Chitwan, Nepal. Pseudomonas fluorescens not only enhances the plant growth but also controls the fungal pathogens by production of anti fungal metabolites. Please reply.
