Abstract A Novel cold-active chitin deacetylase from Shewanella psychrophila WP2 (SpsCDA) was overexpressed in Escherichia coli BL21 and employed for deacetylation of to chitosan. The produced chitosan characterized, its antifungal activity investigated against Fusarium oxysporum . purified recombinant SpsCDA appeared as a single band on SDS-PAGE at approximately 60 kDa, specific 92 U/mg. optimum temperature pH were 15 °C 8.0, respectively, the enzyme significantly enhanced presence NaCl. bioconversion by accomplished 72 h, yield 69.2%. solubility estimated be 73.4%, degree 78.1%. molecular weight 224.7 ± 8.4 kDa with crystallinity index (CrI) value 18.75. Moreover, FTIR XRD spectra revealed characteristic peaks enzymatically compared standard chitosan, indicating their structural similarity. inhibited spore germination F. minimum inhibitory concentration (MIC) 1.56 mg/mL. potential effect is attributed inhibition accompanied ultrastructural damage membranes leakage cellular components, evidenced transmission electron microscopy (TEM), accumulation reactive oxygen species (ROS) that confirmed fluorescence microscopy.

Abstract A remarkable one‐third of global food production is wasted, resulting in significant economic damage and escalating insecurity. To address this sustainability challenge, freshness identification packaging using intelligent materials has gained traction. This work introduces a chitosan‐ graft ‐gelatin (CS‐g‐GEL) hydrogel, incorporating pH‐responsive dye, bromothymol blue (BTB), as colorimetric indicator to monitor the spoilage chicken breasts. The successful formulation hydrogels verified FTIR, AFM, SEM, TGA, 1 HNMR characterization techniques. At pH 5 7.4, swelling capacity hydrogel 790% 470%, respectively. rise colony‐forming units (CFU) from 5.5 on day 1–7.4 log CFU g −1 7 indicate microbial activity, carbon dioxide due deteriorating decreases package. Additionally, CO 2 concentrations 3.2 1–22.1 (% v/v) 7, while O levels 23.8 near 0.5 same period. developed demonstrated serve smart visual offers new dimension use toward challenge.

Abstract The growing presence of pharmaceutical pollutants in aquatic environments poses significant threats to both human health and ecosystems. Despite their crucial role healthcare, pharmaceuticals enter water systems through various sources, making them some the most critical environmental contaminants. Traditional wastewater treatments, which are classified into physical, chemical, biological techniques, often struggle effectively remove pharmaceuticals. Among these methods, adsorption stands out as a reliable versatile approach for removing organic enhancing efficiency treatment processes. Biopolymers, particularly chitosan, gaining attention due numerous advantages, including biocompatibility, biodegradability, affordability, high capability, non‐toxicity, availability from diverse natural sources. Chitosan, hydrophilic biopolymer, can be chemically modified by incorporating nanoparticles (e.g., metal oxides, carbon‐based materials, magnetic particles) boost its efficiency. These advancements enable chitosan‐based nanocomposites range pharmaceuticals, antibiotics, analgesics, hormones, water. This review examines latest developments nanocomposite adsorbents, emphasizing fundamental mechanisms, optimization conditions, kinetic behaviors, isotherm models. factors collectively determine capturing pollutants. Moreover, underscores potential materials remediation, offering valuable insights application future research directions. Ultimately, aim this is provide insight offer an innovative effective solution challenge contamination By addressing key challenges utilizing advanced material designs, adsorbents hold great promise sustainable efficient removal systems.
