Bioaccumulation of cadmium and lead by Shewanella oneidensis isolated from soil in Basra governorate, Iraq

In the present study heavy metals resistant bacteria were isolated from soil collected from Al-Zubair district in Basra governorate south of Iraq. On the basis of morphological, biochemical, 16S rRNA gene sequencing and phylogeny analysis, the isolates were authentically identified as Shewanella oneidensis in addition to Bacillus thuringiensis and Deinococcus radiodurans. The minimal inhibitory concentration (MIC) of...

Prevalence of exfoliative toxins and toxic shock syndrome toxin-1 encoding genes among coagulase positive Staphylococcus isolated from human and animal sources

This study was undertaken to determine the prevalence of coagulase positive staphylococcus (CPS) in Jordan and to investigate the presence of genes encoding exfoliative toxins (eta, etb), and toxic shock syndrome toxin-1 (tst). Seven hundred and fifty three samples were used including 273 obtained from human sources and 480 from animals (sheep, cows, and goats). One hundred and sixty seven isolates were identified as...

Growing varieties durum wheat (Triticum durum) in response to the effect of osmolytes and inoculation by Azotobacter chroococcum under salt stress

This study was conducted to determine the effect of plant growth promoting rhizobacteria Azotobacter chroococcum AZ6 isolated from arid soil and osmolytes such as glycine betaine (GB) or proline (P) on the growth of durum wheat varieties under salinity stress. Inoculation by A. chroococcum AZ6 in the presence or absence of P (5 mM) or GB (5 mM) reduced substantially the effect of salt stress on plant growth parameters...

In vitro evaluation of probiotic potential of five lactic acid bacteria and their antimicrobial activity against some enteric and food-borne pathogens

Lactic acid bacteria (LAB) present many important properties in food manufacturing, such as improvement of physical characteristics and the production of lactic acid that aids in the increase of the shelf life of food products. Also, LAB can suppress growth of pathogens, control of serum cholesterol level, modulate immune system, and improve lactose digestion. Five standard (Lactobacillus paracasei, Lactobacillus...
