  • biosynthesis of silver nanocrystals by Bacillus Licheniformis
    Colloids and Surfaces B: Biointerfaces, 2008
    Co-Authors: Kalishwaralal Kalimuthu, Ramkumarpandian Suresh Babu, Deepak Venkataraman, Mohd Bilal, Sangiliyandi Gurunathan
    Abstract:

    The use of microorganisms for the synthesis of nanoparticles is in the limelight of modern nanotechnology. Using the bacterium Bacillus Licheniformis, the biosynthesis of silver nanoparticles was investigated. These silver nanoparticles were characterized by means of UV-vis spectroscopy, scanning electron microscopy (SEM), electron diffraction spectroscopy (EDX) and X-ray diffraction (XRD). The nanoparticles exhibited maximum absorbance at 440 nm in UV-vis spectroscopy. The XRD spectrum of silver nanoparticles exhibited 2theta values corresponding to the silver nanocrystal. SEM micrographs revealed the formation of well-dispersed silver nanoparticles of 50 nm, and the presence of silver was confirmed by EDX analysis.

    Abstract The use of microorganisms for the synthesis of nanoparticles is in the limelight of modern nanotechnology. Using the bacterium Bacillus Licheniformis , the biosynthesis of silver nanoparticles was investigated. These silver nanoparticles were characterized by means of UV–vis spectroscopy, scanning electron microscopy (SEM), electron diffraction spectroscopy (EDX) and X-ray diffraction (XRD). The nanoparticles exhibited maximum absorbance at 440 nm in UV–vis spectroscopy. The XRD spectrum of silver nanoparticles exhibited 2 θ values corresponding to the silver nanocrystal. SEM micrographs revealed the formation of well-dispersed silver nanoparticles of 50 nm, and the presence of silver was confirmed by EDX analysis.

  • Application Effect of Bacillus Licheniformis L_3 on Corn and Rice
    Hubei Agricultural Sciences, 2009
    Co-Authors: Lin Kai-chun
    Abstract:

    This paper studied the effects of the fermentation broth,supernatant and pellet of Bacillus Licheniformis L3 on corn and rice respectively.The results showed that the fermentation broth of Bacillus Licheniformis L3 had significantly effect on corn.It was mainly caused by the pellet of the fermentation broth of Bacillus Licheniformis L3.Analysis of the fermenta-tion broth showed that cytokinin was produced by Bacillus Licheniformis L3.

  • Optimization of Bacillus Licheniformis L3 Fermentation Medium by Response Surface Method
    Hubei Agricultural Sciences, 2009
    Co-Authors: Lin Kai-chun
    Abstract:

    Bacillus Licheniformis L3 showed strong fungicidal activity against Fusarium spp. and Sclerotinia spp. Based on the single-factor test,carbon source,soybean powder and K2HPO4 were determined as necessary for spore formation of Bacillus Licheniformis L3 through the Plackett-Burman design. The medium consist with soybean flour 8 g·L-1,K2HPO4 2 g·L-1,carbon 32.20 g·L-1,MgSO4 0.5g·L-1,yeast extract 2.5 g·L-1 were defined as the optimum medium for Bacillus Licheniformis L3 growth and spore formation,through the center combination of design and response surface analysis. With the optimum medium the live bacteria number was 100.20×108CFU·mL-1,nearly double than that with the initial culture medium.
