This article highlights the research work carried out in the production of inulinases from various inulin substrates using strains of bacteria, yeast and fungi. Inulin is one of the numerous polysaccharides of plant origin that contains glucose or fructose. It is used as a substrate in industrial fermentation processes and in food industries due to its(More)
A novel biosynthesis route for silver nanoparticles (Ag-NPs) was attempted in this present investigation using aqueous extracts of Trachyspermum ammi and Papaver somniferum. The main constituents in T. ammi are thymol, p-cymene and γ-terpinene, while P. somniferum consists of morphine and codeine. The essential oil in T. ammi was found to be a good reducing(More)
This article recapitulates the scientific advancement towards the greener synthesis of silver nanoparticles. Applications of noble metals have increased throughout human civilization, and the uses for nano-sized particles are even more remarkable. "Green" nanoparticle synthesis has been achieved using environmentally acceptable solvent systems and(More)
This paper discusses the techniques that can increase the resolution of a digital image and its applications. The current methods used for increasing the resolution are the interpolation methods, which are Bicubic that is the slowest but produces the best estimation of new pixel values. Bilinear is faster than Bicubic, but does a weaker job. Both Bicubic(More)
