The present study is aimed at assessing the ability of Pseudomonas sp. AN29 to uptake Hg from the metal contaminated environment. The minimum inhibitory concentration (MICs) of Hg was 500 μg/ml. Pseudomonas sp. AN29 could tolerate Pb (600 g/ml), Cu (200 g/ml), Cd (50 g/ml), Zn (50 g/ml), Ni (550 g/ml) and Cr (150 g/ml). The isolate showed typical growth curve but phases (lag and log) exte...

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...

abstract in this study a greenhouse experiment was conducted to evaluate the role of acc deaminase enzyme on alleviation of salinity stress of canola plant. canola plants were exposed to pseudomonas fluorescens strain p12 which contains a rhizobacter capable of producing pseudomonas fluorescens in comparison with plants exposed to mutant pm12 unable to produce the required enzyme. the mutant wa...

The taxonomic position of Pseudomonas sp. B13(T), isolated as a 3-chlorobenzoate-degrading organism and used for several groundbreaking studies on the enzymology and genetics of the degradative pathway for haloaromatic compounds, was studied in detail. The previously performed physiological studies, the detection of ubiquinone Q-9, the polyamine pattern with putrescine and spermidine as major p...

biodegradation of polycyclic aromatic hydrocarbons, toxic compounds widely distributed in the environment by bacteria, is a cheap and safe cleaning up method. the present study attempts to isolate and characterize dioxygenase-producing bacteria which are able to degrade phenanthrene and pyrene from refinery soils. it also aims to assess in vitro biodegradation. to do so, two contaminated soil s...

vanillin is undoubtedly one of the most popular and widely used flavoring agents in the world. natural vanillin is extracted from vanilla beans and is relatively expensive. moreover, the consumer demand for natural vanillin highly exceeds the amount of vanillin extracted by plant sources. this had led to the investigation of alternative routes for its production such as microbial bioconversion....

Plant growth promoting endophytic bacteria (PGPB) isolated from Brassica napus were inoculated in two cultivars of Helianthus tuberosus (VR and D19) growing on sand supplemented with 0.1 mM Cd or 1 mM Zn. Plant growth, concentrations of metals and thiobarbituric acid (TBA) reactive compounds were determined. Colonization of roots of H. tuberosus D19 by Pseudomonas sp. 262 was evaluated using co...

Growth-dependent cell-cell communication termed quorum sensing is a key regulatory system in bacteria for controlling gene expression including virulence factors. In this study five potential bacterial pathogens including Bacillus sp. W2.2, Klebsiella sp. W4.2, Pseudomonas sp. W3 and W3.1 and Serratia sp. W2.3 were isolated from diseased Tilapia fish in Malaysia, supplied by the leading global ...
