Cyclic Depsipeptide Producing Fluorescent Pseudomonads Exerts Antifungal Activity against Fungal Pathogens of Maize (Zea mays) | Chapter 05 | Theory and Applications of Microbiology and Biotechnology Vol. 2
Cyclic lipopeptides (CLPs) with antibiotic, biosurfactant producing fluorescent pseudomonads were isolated from sugar beet-maize intercropped in sandy loam soils at Maize Research Station, Vagarai, TNAU. Approximately 20 fluorescent pseudomonads from sandy loam soils were isolated by using two different growth media. The strains were distinguished based on their growth, CFU/g, fluorescence, and pigment production. Growth inhibition of maize pathogens by CLP producing fluorescent pseudomonads strains were studied by dual culture experiments. The impact of CLP producing flurorescent pseudomonads strain on the zoospores of Downy mildew pathogen of maize was studied by direct microscopy and encysted zoospores were observed. Invitro, biochemical experiments confirmed the presence of Viscosinamide producing strain among the fluorescent pseudomonads isolates in terms of utilization of C and N sources. The particular strain was tested for its growth promoting activity by treating the maize s...
