a field experiment was conducted during 2009-2011 at the aligarh muslim university agricultural research farm, india, to evaluate the efficacious nature of some oil-seed cakes such as neem cake and castor cake, a botanical calotropis procera and phosphate solubilizing bacteria (psb) pseudomonas fluorescens singly and in various combinations, on the growth and productivity of trigonella plant. g...

contamination sites of pseudomonas fluorescenswere traced in the production line for milk pasteurization in a large dairy plant in shiraz, iran. samples of raw and pasteurized milk were collected at six sites along the line. all milk samples were incubated at 7°c until the aerobic plate count had reached 10 6 -10 7 cfu ml-1. colonies were picked randomly and identified. no growth of gram negati...

Pseudomonas fluorescens Pf0-1 showed positive chemotactic responses toward 20 commonly-occurring l-amino acids. Genomic analysis revealed that P. fluorescens Pf0-1 possesses three genes (Pfl01_0124, Pfl01_0354, and Pfl01_4431) homologous to the Pseudomonas aeruginosa PAO1 pctA gene, which has been identified as a chemotaxis sensory protein for amino acids. When Pf01_4431, Pfl01_0124, and Pfl01_...

The objective of this study was to evaluate previously isolated non pathogenic Pseudomonas fluorescens biovars inhibitory effect against pathogenic A. hydrophila in vitro and in vivo. The results showed that P. fluorescens biovars have in vitro antibacterial inhibitory effect against A. hydrophila. Also, feeding O. niloticus diet containing P. fluorescens biovars showed resistance against A. hy...

Pseudomonas fluorescens strains PA4C2 and PA3G8 and Pseudomonas putida strain PA14H7 were isolated from potato rhizosphere and show an ability to inhibit the growth of Dickeya phytopathogens. Here, we report their draft genome sequences, which provide a basis for understanding the molecular mechanisms involved in antibiosis against Dickeya.

This study was carried out at the forest nursery of Department of Forestry, Faculty of Agriculture and Regional Research Station, Wadura SKUAST-K, Sopore, Kashmir during 2006 and 2007 to examine the role of live biofertilizers in litter decomposition and nutrient release in Salix fragilis under natural Salix stands. The experiment was laid in completely randomised design with three replications...

the chitinase producing ability of pseudomonas fluorescens strains viz., pf1, pb2 and fp7 was evaluated in a culture medium with and without a chitin source. the addition of 1% (v/v) chitin in culture medium significantly increased the bacterial population and chitinase activity. among three strains tested, fp7 responded well to the addition of chitin by producing 31.2% increased chitinase in c...

A novel ice-nucleating bacterium (INB) was isolated from Ross Island, Antarctica. INBs could be isolated more frequently than was generally thought. INB strain IN-74 was found in the white colony group. Strain IN-74 was identified from its taxonomic characteristics as a novel INB, Pseudomonas antarctica IN-74. When strain IN-74 was cultured aerobically in a medium consisting of the ice-nucleati...
