Interspecific competition in bacteria governs colony growth dynamics and pattern formation. Here, we demonstrate an interesting phenomenon of interspecific competition between Bacillus cereus MSM-S1 and Pseudomonas sp. MSM-M1, where secretion of an inhibitor by Pseudomonas sp. is used as a strategy for survival. Although B. cereus grows faster than Pseudomonas sp., in the presence of Pseudomona...

Strains of Pseudomonas putida, Pseudomonas sp., and Pseudomonas aeruginosa were examined for their ability to grow in the presence of the iron chelator, ethylenediamine-di-(o-hydroxyphenylacetic acid). In vitro fungal inhibition assays showed that the isolates varied in their ability to inhibit the growth of representative fungal plant pathogens. Fungal inhibition in vitro was superior to that ...

Toluene oxidation activity in Pseudomonas mendocina KR1 and Pseudomonas sp. strain ENVPC5 was induced by trichloroethylene (TCE), and induction was followed by the degradation of TCE. Higher levels of toluene oxidation activity were achieved in the presence of a supplemental growth substrate such as glutamate, with levels of activity of up to 86% of that observed with toluene-induced cells. Act...

the present study is aimed at assessing the ability of   pseudomonas sp. an29 to uptake hg2+ from the metal contaminated environment. the minimum inhibitory concentration (mics) of hg   2+ was 500 μg/ml. pseudomonas   sp. an29 could tolerate pb   2+ (600 g/ml), cu2+ (200 g/ml), cd2+ (50 g/ml), zn2+ (50 g/ml), ni2+ (550 g/ml) and cr   6+ (150 g/ml). the isolate showed typical g...

A study was undertaken on exploitation of indigenous Pseudomonas strains isolated from tea rhizosphere for disease control and productivity in tea. This included in vitro studies on plant growth promotion and biocontrol properties like production of phytohormones, siderophore, hydrogen cyanide, phosphate solubilization, and resistance to agrochemicals. The ability of Pseudomonas sp, was determi...

A bacterial strain, isolated from a cyanobacterial culture, was identified as Pseudomonas sp. strain X40. Under iron-limiting conditions, the Pseudomonas sp. produced aerobactin, a dihydroxamate siderophore previously found only in the family Enterobacteriaceae. Aerobactin was identified by electrophoretic mobility, spectrophotometric titration, proton nuclear magnetic resonance spectroscopy, m...

The gene loci fcs, encoding feruloyl coenzyme A (feruloyl-CoA) synthetase, ech, encoding enoyl-CoA hydratase/aldolase, and aat, encoding beta-ketothiolase, which are involved in the catabolism of ferulic acid and eugenol in Pseudomonas sp. strain HR199 (DSM7063), were localized on a DNA region covered by two EcoRI fragments (E230 and E94), which were recently cloned from a Pseudomonas sp. strai...
