Optimal Conditions for Isolation of Nanocrystalline Cellulose Particles
Nanocrystalline cellulose particles are new class of cellulose materials that can find the wide application in various technical areas, biotechnology and medicine. The nanoparticles are usually made by treatment or initial cellulose samples with concentrated sulfuric acid (SA) at various temperatures and following mechanical or ultrasound disintegration. Unfortunately, conditions of existing me...
متن کاملRheological properties of nanocrystalline cellulose suspensions.
Rheological behavior, including linear and nonlinear, as well as transient rheology of nanocrystalline cellulose (NCC) suspensions was studied in this work. Two kinds of polymer solutions, aqueous poly(vinyl alcohol) (PVA) with flexible chain structure and aqueous carboxymethyl cellulose (CMC) with semi-rigid chain structure, were used as the suspension media to further explore the role that th...
متن کاملCellulose Isolation Methodology for NMR Analysis of Cellulose Ultrastructure
In order to obtain accurate information about the ultrastructure of cellulose from native biomass by 13C cross polarization magic angle spinning (CP/MAS) NMR spectroscopy the cellulose component must be isolated due to overlapping resonances from both lignin and hemicellulose. Typically, cellulose isolation has been achieved via holocellulose pulping to remove lignin followed by an acid hydroly...
متن کاملOptimal Conditions for Extraction and Purification of Penicillinase Enzyme
Background and Objective: The present study aimed to evaluate the optimum conditions for extracting and purifying penicillinase enzyme. The enzyme source was Bacillus licheniformis 6346 obtained from the Iranian Research Organization for Science and Technology. Materials and Methods: B. licheniformis was cultured in a medium containing mineral salts, nitrogen compounds, and cultured carbon sou...
متن کاملPreparation Methods for Nanocrystalline Cellulose - Acid hydrolysis and various cellulose sources
The aim of this project has been to prepare nanocrystalline cellulose (CNC) from hydrochloric acid hydrolysis and optimise the process. CNC was also prepared from sulphuric acid hydrolysis to use as a reference. The starting material in both these processes was microcrystalline cellulose (MCC), therefore another cellulose source was used to try and prepare CNC from. The cellulose was extracted ...
