Identification of Some Molecular Traits in Fluorescent Pseudomonads with Antifungal Activity
We assessed a collection of 47 fluorescent Pseudomonas spp., some with known biological control activity against certain soil-borne phytopathogenic fungi such as, Macrophomina phaseolina, Rhizoctonia solani, Phytophthora nicotianae var. parasitica, Pythium sp. and Fusarium sp. in vitro and the potential to produce known secondary metabolites such as, siderophore, HCN and protease. The resu...
متن کاملSiderophores of fluorescent pseudomonads.
Though iron is fourth in abundance in the earth crust it is not readily available to many m icroorga nisms: In the early days of earth life developed in a reductive atm osphere where iron necessary for many physiological processes was abundant in its divalent form. Fe2+-salts are sufficiently w ater soluble to provide an adequate supply of this elem ent to the cells. But as a consequence of th...

متن کاملIsolation, characterization, and effect of fluorescent pseudomonads on micropropagated sugarcane.
In this study, we report on the isolation, identification, and characterization of seven fluorescent pseudomonads isolated from the roots, shoots, and rhizosphere soil of sugarcane and their impacts on the growth of sugarcane plantlets. 16S rRNA gene sequence of five isolates showed close homology with Pseudomonas putida, one with Pseudomonas graminis, and one with Pseudomonas fluorescens. Phys...
متن کاملAntagonistic effect of fluorescent pseudomonads against Macrophomina phaseolina that causes charcoal rot of groundnut.
Maximum colony growth inhibition was observed due to Pseudomonas PS2 (74%) as compared to PS1 (71%) on trypticase soy agar (TSM) plates after 5 days of incubation. Light and scanning electron microscopic examination showed hyphal coiling, vacuolation, coagulation and granulation of cytoplasm resulting in lysis of hyphae of M. phaseolina by pseudomonads. Cell free culture filtrates of strains PS...
