Green Conversion of Agroindustrial Wastes into Chitin and Chitosan by Rhizopus arrhizus and Cunninghamella elegans Strains

Green Conversion of Agroindustrial Wastes into Chitin and Chitosan by Rhizopus arrhizus and Cunninghamella elegans Strains

This article sets out a method for producing chitin and chitosan by Cunninghamella elegans and Rhizopus arrhizus strains using a green metabolic conversion of agroindustrial wastes (corn steep liquor and molasses). The physicochemical characteristics of the biopolymers and antimicrobial activity are described. Chitin and chitosan were extracted by alkali-acid treatment, and characterized by inf...

Microbial enhance of chitosan production by Rhizopus arrhizus using agroindustrial substrates.

This study investigated the potential of Rhizopus arrhizus UCP 402 for producing chitosan using corn steep liquor and honey as agroindustrial nitrogen and carbon sources. A complete factorial design was used to assess the improved biomass and chitosan production. The results were evaluated using Pareto charts (Statistica 7.0 software). The chitosan obtained was characterized by X-ray diffractio...

an investigation into translation of cultural concepts by beginner and advance student using think – aloud protocols

this research aims at answering the questions about translation problems and strategies applied by translators when translating cultural concepts. in order to address this issue, qualitative and quantitative study were conducted on two groups of subjects at imam reza international university of mashhad. these two groups were assigned as beginner and advanced translation students (10 students). ...

The antimicrobial of chitin and chitosan extracted from shrimp shell (Palameon elegans)

Palaemon elegans are distributed over a wide coastline of ocean and sea waters. distilled form (chitosan) is a natural polymer with antimicrobial properties that is naturally present in the exoskeleton of crustaceans, including shrimp. Chitin and chitosan are widely used in the pharmaceutical, cosmetic, agricultural, biomedical, food preparation and storage industries. 977 pieces of P. elegans ...
