Research ArticleOpen accessIn the keywordsEFFECT OF COPPER SULPHATE AND COBALT CHLORIDE ON GROWTH OF THE IN VITRO CULTURE TISSUES FOR DATE PALM (PHOENIX DACTYLIFERA L.) CV. ASHGARAhmed Madi Waheed AL-MayahiThis study was carried out to investigate the effects of copper sulphate and cobalt chloride on propagation of date palm cv. Ashgar in vitro. The rate of callus proliferation was significantly higher in the medium supplemented with 2 µM copper sulphate and 2 µM cobalt chloride together (p<0.05). Addition of copper sulphate and Cobalt chloride to the medium was most … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 27 Nov 2013 · 8,456 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Dose-Response of Zinc and Manganese on Siderophores ProductionMehri Ines, Khessairi Amel, Turki Yousra et al.Problem statement: This study was conducted to find and determine whether the siderophores of the four environmental Pseudomonas spp. isolates possess a sequestering activity towards essential transition metals (Zn and Mn) other than iron. Approach: Four fluorescent Pseudomonads isolated from various environments, were characterized analytically (Isoelectric focusing), biologically (pyoverdine-mediated uptake) and genetically (16S rDNA sequencing). By means of spectrophotometric measurements, … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 10 Mar 2012 · 7,768 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEnhanced Production of Extracellular Alkaline Lipase by an Improved Strain of Pseudomonas aeruginosa MTCC 10,055Deepali Bisht, Santosh Kumar Yadav, Nandan Singh DarmwalProblem statement: Lipases are industrially important enzymes having applications in numerous industries. For easy commercialization it is necessary to produce lipases at industrial level which could be achieved by strain improvement and medium formulation. Approach: In the present study strain improvement of Pseudomonas aeruginosa MTCC 10,055 was done by chemical mutagenesis using mutagen 4-nitroquinoline1-oxide for alkaline lipase production. Different fermentation … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 24 Nov 2011 · 8,760 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBasal Salt Requirements Differ According to Culture Stage and Cultivar in Date Palm Somatic EmbryogenesisJameel M. Al-KhayriProblem statement: Various media formulations differing in basal salt composition are arbitrary selected to provide essential nutrients for plant in vitro cultures. Evidence suggests that in vitro response to various media formulations varies among genotypes and depends on the culture stage. This study examined the efficacy of five basal salt formulations on callus growth and somatic embryogenesis in date palm … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 1 · 27 May 2011 · 10,156 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMedia Improvement for Hydrogen Production Using C. acetobutylicum NCIMB 13357Mohd Sahaid Kalil, Hisham Salem Saleh Alshiyab, Wan Mohtar Wan YusoffProblem statement: Some component of fermentation medium showed to reduce the bacterial production of hydrogen. Approach: Reinforced clostridium medium is a selected medium for Clostridium species. Reformulation this medium regarding hydrogen production may focus on such medium composition that enhance or reduce the bacterial productivity. The optimum pH and temperature for hydrogen production were at initial pH of 7.0 and … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,255 accessesView PDFCite

Research ArticleOpen accessIn the keywordsStudy of the Optical and Physical Roles of a Dielectric Laser Dye Solvent Which Affects on the Dye Laser OperationRiyad A.M. GhazyIt is well known that when the pump laser beam incidence on the laser dye liquid it will be absorbed. This absorption tends to heat the laser active medium, which is the laser dye solution. In view of this the correlated property of that active medium well change tends to shift the operated frequency and wavelength. Therefore, one of most … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,862 accessesView PDFCite
