Chitosan was chemically extracted with a process yield of ca. 63 % and a degree of deacetylation of ca. 65 %. Further chitosan was characterised by FTIR, DSC, XRD and zeta potential. Antimicrobial and antioxidant activities were tested by microbicide concentration and ABTS methods. fucose foods expressed chitosan was supported to be antioxidant and antimicrobial against Escherichia coli, Candida albicans, Staphylococcus aureus (methicillin resistant and susceptible variants).
Vaginal pictures using chitosan educed from crayfish cuticles were developed by solvent casting, and the biological profile was quized in simulated vaginal fluid as a proof of concept. The main data showed that the vaginal flicks prepared were active against several micro-organisms responsible for vaginal contagions, manifesting their potential in the field.Sustainable Lignin-Reinforced Chitosan Membranes for Efficient Cr(VI) Water Remediation.The pollution of aquatic environsses is a arising problem united to population growth and intense anthropogenic activities. Because of their potential impact on human health and the environment, special attention is paid to contaminations of egressing concern, namely heavy metals this work projects the use of naturally gained cloths capable of adsorbing chromium (VI) (Cr(VI)), a contaminant bonked for its potential toxicity and carcinogenic gists, leaving a sustainable alternative for water remediation. For this purpose, membranes established on chitosan (CS) and chitosan/Kraft lignin (CS/KL) with different portions of lignin (0 and 0 g) were germinated using the solvent casting technique. The introduction of lignin imparts mechanical strength and subdues welling in pristine chitosan.
The CS and CS/0 KL membranes executed excellently, absenting Cr(VI) at an initial 5 mg/L concentration. After 5 h of contact time, they indicated about 100% removal. The adsorption process was analysed expending the pseudo-first-order model, and the interaction between the polymer matrix and the contaminant was ascribed to electrostatic interactions. Therefore, CS and CS/KL membranes could be low-cost and efficient adsorbents for heavy alloys in wastewater treatment applications.Fatty acid-altered chitosan and nanoencapsulation of essential oils: A snapshot of coverings.Chitosan (CS) and its modification with fatty acid (FA) in addition to the nanoencapsulation with essential oils (EOs) have issued as predicting attacks with diverse coverings, particularly in food and fruit preservation. This review aims to curate data on the outlooks of CS altered with FA as nanostructures, sufficing as carriers for EOs and its application in the preservation of fruits.
A narrative review with no restricted period was used for the general overview of CS and schemes for its modification with FA. Report on CS modified with FA and nanoencapsulation with EO and their coatings were assessed. The scenes of CS altered with FA and EO nanoencapsulation in food and fruit preservation were adumbrated. Most chitosan-fatty acid (CS-FA) disciplines have found relevance in water, medical and pharmaceutical industries, with few sketchs on food preservation. CS-FA formulation with EOs shows substantial potential in saving yields and will significantly impact the food industry in the future by extending the shelf life of yields and foreshortening food waste.Chitosan Phytate Nanoparticles: A Synergistic Strategy for Effective Dental Caries Prevention.Dental caries is a widespread oral disease that gets a significant medical challenge.
Traditional caries prevention methods, primarily the application of fluoride, often fall short in effectively destroying biofilms and preventing enamel demineralization, thereby allowing limited efficacy in arresting the progression of caries over time. To address this issue, we have developed a green and cost-effective synergistic strategy for the prevention of dental caries.
