Identification of exopolysaccharides produced by fluorescent pseudomonads associated with commercial mushroom (Agaricus bisporus) production.
The acidic exopolysaccharides (EPSs) from 63 strains of mushroom production-associated fluorescent pseudomonads which were mucoid on Pseudomonas agar F medium (PAF) were isolated, partially purified, and characterized. The strains were originally isolated from discolored lesion which developed postharvest on mushroom (Agaricus bisporus) caps or from commercial lots of mushroom casing medium. An...
متن کاملIsolation and characterization of fluorescent pseudomonads and their effect on plant growth promotion.
Seven isolates of fluorescent pseudomonads were evaluated for their effect on plant growth promoting traits, both under normal and saline conditions using tomato plants. Fifteen rhizosphere samples from crop fields' of rice, chilly, ragi, beans and garden soils from different regions of India were collected and used for further study. They were characterized morphologically and biochemically wh...
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 کاملFluorescent Pseudomonads Associated with the Rhizosphere of Crops - an Overview
Environmental concerns have led to the need of sustainable use of natural resources. The conventional agriculture caused considerable impacts on soils and waters. It is important to change certain agricultural managements to environmental cleaner techniques. The sustainable agriculture has pointed many approaches and techniques to reduce environmental impact. One of those strategies is the util...
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...
