In the current study, extracellular biosynthesis of silver nanoparticles (AgNPs) was carried out using aqueous extracts of green Calligonum comosum stem, besides Fusarium sp. Synthesized AgNPs were characterized using ultraviolet (UV)–Vis spectrophotometer, transmission electron microscopy (TEM) and zeta potential. Moreover, biosynthesized AgNPs were estimated for the scavenging ability on DPPH radical...
Improved xylanase production was carried out through optimization of environmental stresses during spore preservation, seed cultivation and batch fermentation and identifies the markers at various stages. The maximum spore size (radius 6.5 µm) of Aspergillus niger was noticed after 28 days of spore preservation. During seed cultivation, the hypha formed alongside of germination tube (length 196.8 µm)...
An antibacterial peptide-encoding gene from alfalfa seeds, alfAFP, was fused to the C-terminal part of chitin-binding domain (CBD) of the rice chitinase-encoding gene (CBD-alfAFP) and introduced to tobacco by Agrobacterium-mediated transformation. Polymerase chain reaction (PCR) technique was used to confirm the integration of the recombinant CBD-alfAFP encoding gene in transgenic tobacco plants....
