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...
متن کاملGreen 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...
متن کاملVentriculitis due to infection with Rhizopus arrhizus
A 52-year-old heart-lung transplant patient presented to the emergency department with acute onset of neurologic symptoms. MRI showed ballooning of the left ventricle, midline shift and contrast enhancement in the anterior horn of the left ventricle. Ventricle neuroendoscopy revealed whitish, floccose aerial structures within the left ventricle. Brain biopsy cultures grew Rhizopus arrhizus. The...
متن کاملSpecies and Varieties in the Rhizopus Arrhizus-rhizopus Oryzae Group as Indicated by Their Dna Complementarity
DNA renaturation experiments gave evidence to conclude that Rhizopus arrhizus, R. OIyzae, R. delemar, Amylomyces rou.xii, R. delemar var. minimus, R. delemar var. multiplicisporus, R. arrhizus var. delemar, R. chungkuoensis var. isqfermentarius, and R. javanicus var. kawasakiensis can be accommodated in three taxa, namely, R. arrhizus var. arrhizus, R. arrhizus var. rozedi, and R. arrhizus var....
متن کاملEnhanced Fumaric Acid Production by Fermentation of Xylose Using a Modified Strain of Rhizopus arrhizus
An enhanced, xylose-utilizing strain of Rhizopus arrhizus was successfully developed via modification using media with increasing concentrations of xylose. Xylose, a relatively cheap monosugar that can be easily obtained from corncobs, rice straw, and vinasse, was the sole carbon source used for both the seed culture phase and the fermentation process. After modification, this newly improved st...
