Fabrication Application Biomass Composites Safety Water Treatment Properties

In this work, a biomass composite material (CS@NC@PA-Na) was fixed from chitosan (CS), nano-cellulose (NC) and sodium phytate (PA-Na). The prepared productions were characterized by scanning electron microscopy (SEM), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectrometry (XPS) and X-ray diffraction (XRD). The fire/water safety and antimicrobial places of the CS@NC@PA-Na were fully analyzed. The resolutions designated CS@NC@PA-Na (50 mg) could effectively reduce the concentration of methyl orange by 85 % under 30 min adsorption only 5 wt% CS@NC@PA-Na could increase the limiting oxygen index (LOI) value of epoxy resin composite from 24 to 30 %, and decrease the peak heat/smoke release rate by 29 and 33 %, respectively CS@NC@PA-Na also presented excellent antibacterial effect. This work caters an efficient, feasible and eco-friendly route for large-scale production of multi-functional CS-finded biomass textiles that could be used in the subjects of fire safety and environmental conservation.Maillard reaction for nucleation of polymer quantum dots from chitosan-glucose conjugate: Antagonistic for cancer and viral diseases.

Polymer dots (PDs) ingrained from biopolymers are qualifyed by their biocompatibility & non-toxicity to be superiorly applicable for biomedicines.  Dietary Supplements  of novelty in the current study is to focus on the effect of Maillard reaction for conjugation of chitosan with glucose to enhance the affinity of chitosan as a biological resource of PDs. Chitosan-glucose conjugate was firstly prepared by Maillard reaction. PDs were nucleated from chitosan (C1 acidic, 10 nm & C2 basic, 11 nm) and chitosan-glucose conjugate (C3 acidic, 6 nm & C4 basic, 5 nm). The affinity of chitosan versus chitosan-glucose conjugate as molecular heralds for PDs as antiviral and anticancer labourers was studied. The synthesized PDs were tested against lung cancer (NSCLC, A549) and the judged IC(50) was 282 & 165 μg/mL for PDs (C3 & C4) grained from chitosan-glucose conjugate. The antiviral action of PDs against Coronavirus (229E) was forecasted and the obtained IC(50) for C3 & C4 was 43 and 19 mg/mL, respectively.

PDs impressed from chitosan-glucose conjugate expressed higher anticancer and antiviral activities likened to that flocked from chitosan. Consequently, the modification of chitosan via Maillard reaction enhanced the biological affinity of the geted PDs to be effectively applicable as antitumor and antiviral laborers.Phosphoprotein Profile of Rice (Oryza sativa L.) Seedlings under Osmotic Stress after Pretreatment with Chitosan.This study aims to identify novel chitosan (CTS)-responsive phosphoproteins in Leung Pratew 123 (LPT123) and Khao Dawk Mali 105 (KDML105) as drought-sensitive rice cultivars and differences in the CTS response. Rice seeds were soused in CTS solution before germination, and 2- and 4-week-old rice seedlings sprayed with CTS before osmotic stress bed the following four groupings: (1) seedlings dealed with distilled water; (2) seedlings plowed with CTS; (3) seedlings pretreated with distilled water and subjugated to osmotic stress; and (4) seedlings pretreated with CTS and subjected to osmotic stress. Phosphoproteins of leaf tissues were enriched using immobilised metal affinity chromatography (IMAC) before tryptic digestion and analysis via LC-MS.

Phosphoprotein profiling psychoanalysisses led to the identification of 4721 phosphoproteins staging 1052 and 1040 unique phosphoproteins in the LPT123 and KDML105 seedlings, respectively. In  Amino Acids  to CTS pretreatment before osmotic stress, 22 differently extracted proteins were detected, of which 10 and 12 were identified in the LPT123 and KDML105, respectively. These proteins are typically necessitated in signaling, transport, protein folding, protein degradation, and metabolism. This study provides fruitful data to understand the signal transduction mechanisms of rice seedlings pretreated with CTS before exposure to osmotic stress.Preparation and Characterization of Aronia melanocarpa/Gellan Gum/Pea Protein/Chitosan Bilayer Films.
