Influence of Topical Application of Acetone Solution of Triterpenes on the Chitin Content in the Body Wall (Integument) of fifth Instar Larvae of Silkworm, Bombyx mori (L).
Abstract: Reduction in the chitin deposition in the insect body wall is one of the distinguishing features of juvenoid compound. Ten microliters ( 10 μL ) of different concentrations of acetone solution of standard solvent: Fernasol Methyl Ether (FME) and ten microliters ( 10 μL ) of different concentrations of acetone solution of each triterpene compounds (Squalene; Polypodatetraene; Malabaricane; Lanostane; Hopaneand and Oleanane) were utilized through the topical application to individual …

Recent Trends in Production, Characterization, and Utilization of Fungal Chitosan
Abstract: Chitosan is the second most abundant biopolymer in nature after cellulose that can be extracted from marine sources, as well as from agricultural waste products such as mushrooms or other fungal sources following chitin deacetylation. The consistent production of these glycans by fungi is unaffected by seasonal changes, allowing for precise process control. This results in a more consistent quality of the final product. Currently, crustacean shells and other marine …

Exploring the Boundless Applications of Chitosan: From Biomedical Marvel to Environmental Saviour
Abstract: Chitosan has attracted much interest because of its versatile properties and possible numerous usages in diversified industrial applications. Chitosan is having poor solubility in neutral and basic media and this is limiting its use. Chitosan is not a single polymer and do not have a defined structure. Chitosan is family of molecules with different composition, size & monomer units’ distribution and these characteristics have effect on the biological & technological …

Chitosan: Chemistry, Applications & Economics of Production - A Review
Abstract: Chitosan is a natural poly-cationic linear polysaccharide derived from chitin and also known as de-acetylated chitin. It is derived from partial de-acetylation of chitin. Its low solubility in neutral and alkaline solution limits its application. Chitosan’s chemical modification brings to it new reactive functional properties for different applications. Because of biocompatibility, non-toxicity, low allergenicity and biodegradability, it is used in various applications .This review paper presents the chemistry, literature review …

Response Surface Methodology to Optimize Deproteinization of Green Crab Shells (Carcinus maenas)
Abstract: The crab shells are used as a feedstock for the extraction of either chitin or chitosan and other bioactive materials such as dyes and proteins. The optimum conditions are required for a process development for an effective separation of chitin. The most important parameters for deproteinization of green crab shells have identified the concentration of NaOH, temperature and time of contact. The optimum conditions for deproteinization of Green crab shells …

Biosynthesis of Chitosan mediated nanoparticles for Preservation of Food and Its Antimicrobial activity
Abstract: In this study, chitosan nanoparticles were synthesized from chitosan polymer by ionic gelation method. The chitin was first extracted from Saccharomyces cerevisiae and then deacetylated to chitosan. The presence and characterization of chitosan nanoparticles was investigated by UV-Visible Spectroscopy (UV) and scanning electron microscopy (SEM). The antimicrobial property of these chitosan nanoparticles were studied against E.coli, S.aureus, S.typhi, P.aureginosa, C.albicans and A.niger and compare with chitosan polymer. CSNPs showed higher …
