aloe emodin cancer  and Characterization of Biocomposite Films of Bacterial Cellulose from Kombucha and caked with Chitosan.The purpose of this research is to produce and characterize bacterial cellulose (BC) films coated with chitosan (BC-CH). BC movies were produced in a fermentation medium grinded on Camellia sinensis tea and dextrose (12 days at 25 °C) and subsequently treated with coating-imprinting solvents (CFSs) grinded on chitosan (BC-CH 0%, BC-CH 1%, and BC-CH 1%). As a result, the FTIR spectra of BC and BC-CH 1% showed the main characteristic bands of cellulose and chitosan. In the physicochemical characterization of the celluloids, it was happened that the incorporation of the chitosan coatings did not affect the thickness; however, it falled the luminosity (L*) and increased redness (a*), yellowness (b*), and opacity (75%) the light absorption properties in the UV-Vis range were bettered the application of the CFSs increased: the solubility (64%), the antimicrobial activity against S. aureus (6 mm) and E.

coli (8 mm), as well as the antioxidant activity (57% and 24% free radical scavenging activity), and the content of total oxybenzenes (2 mg GAE/g). Finally, our results suggest that the BC-CH films prepared in the present study show a potential application as active packaging material for food.Application of nickel chitosan nanoconjugate as an antifungal agent for battling Fusarium rot of wheat.Agro-investigators are endlessly tasting to derive a potential biomolecule making antifungal attributes in order to replace the application of synthetic antimycotics on agricultural disciplines. Rot disease often caused by Fusarium solani made severe loss of wheat crops every year. Chitosan and its metallic nano-differentials hold a broad-spectrum antifungal property. Our interdisciplinary study plentys with the application of nickel chitosan nanoconjugate (NiCNC) against Fusarium rot of wheat, in comparison with chitosan nanoparticles (CNPs) and commercial fungicide Mancozeb.

CNPs and NiCNC were qualifyed on the basis of UV-Vis spectrophotometry, HR-TEM, FESEM, EDXS and FT-IR. Both CNPs and NiCNC were geted effective against the fungal growth, of which NiCNC at 0 mg/mL testifyed complete termination of F. solani originated in suitable medium. Ultrastructural analysis of F. solani conidiospores dealed with NiCNC uncovered judged hurts and disruption of the membrane surface. Fluorescence microscopic study divulged generation of oxidative stress in the fungal system upon NiCNC exposure NiCNC exhibited reduction in rot disease incidence by 83% of wheat seedlings which was further affirmed through the observation of anatomical parts of the stem. NiCNC application aids the seedling to overcome the adverse effect of pathogen, which was valued through stress indices attributes.

Chitosan as a potential natural compound to manage plant diseases.The necessity for non-chemical comings has grown as awareness of the perils sticked by pesticides has spread due to its biocompatibility, biodegradability, and bioactivity is one the effective choice in phytopathology. Chitosan is a biopolymer that shortens plant diseases through two main mechanisms: (1) Direct antimicrobial function against pathogens, including plasma membrane damage mechanisms, interactions with DNA and RNA (electrostatic interactions), metal chelating capacity, and deposition onto the microbial surface, (2) Induction of plant defense responses ensuing from downstream signalling, transcription factor activation, gene transcription and finally cellular activation after recognition and binding of chitin and chitosan by cell surface receptors. This biopolymer have potential with capability to battling fungi, bacteria, and viruses phythopathogens. Chitosan is synthesized by deacetylating chitin. The degree of deacetylation and molecular weight of chitosan are variable and have been adverted as important structural arguments in chitosan's biological properties. Chitosan with a higher degree of deacetylation (>70 %) has better biological places.
