PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

In this study, new cellulose – magnetic chitosan composite was readied and their capabilities in terms of dye-adsorption and anti-bacterial action were explained. The readied composites were distinguished by absorption spectroscopy, X-ray diffraction, spectrum of absorption using Fourier transform infrared spectroscopy and scanning electron microscopy. Dye adsorption tests were done utilizing methylene blue (MB) as model contamination. The sorption of the composite was examined as actively and thermodynamically to facilitate filtering out of Methylene Blue (MB) from the aqueous solution. To check the impact of certain features, function of CT (Contact time) is analyzed with initial values of temperature and concentration during the filtering of MB out of the aqueous-solution on the composite. Additionally, thermodynamic parameters ΔH^o, ΔG^o and, ΔS^o determined by using Langmuir-adsorption model. The phenomenon of ‘adsorption with spontaneity’ is signaled by Negative-Gibbs free energy (ΔGo) and the property of positive - adsorption enthalpy (ΔH^o) shows that the procedure is endothermic for the MB. The antibacterial property of the composite was tried against Gram-positive and Gram-negative microorganisms, and they revealed minimal inhibitory conc. (MICs) of 0.1 g/mL. This investigation shows that readied composite has the potential as a green adsorbent just as anti-microbial agent and offered the one of a kind preferred position of advantageous use.
