Characterization of acid soluble collagen from skin of variable torpedo ray(Torpedo sinuspersici) and antibacterial activity Sekar Harikrishnan, Murugan Parivallal, Shanmugam Sudarshan, Jeevanandam Vaishnavi, Aruliah Rajasekar, Vasudevan Ramachandran, Sandhanasamy Devanesan, Mohammad Ahmad Wadaan, Jayaraman Narenkumar Next Nanotechnology, 2026 This study explores the extraction and characterization of acid-soluble collagen (ASC) from the skin of Torpedo sinuspersici , commonly known as the varied torpedo ray. The isolated collagen was analyzed using SDS-PAGE, UV–visible spectroscopy, Fourier-transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM). SDS-PAGE confirmed the presence of type I collagen, comprising two α chains (α1 and α2, ∼92 kDa) and one β chain (∼172 kDa). UV–visible analysis showed a characteristic absorbance below 250 nm, while FTIR spectra revealed prominent amide bands (A, B, I, II, and III), indicating key functional groups. SEM imaging provided insights into the collagen’s crystalline structure. High-performance liquid chromatography (HPLC) revealed glycine as the dominant amino acid, followed by proline and hydroxyproline. The findings highlight the potential of ray fish skin as a sustainable source of collagen, with demonstrated antibacterial activity against clinically relevant bacterial strains. These results support its application in developing biomaterials with antimicrobial properties.
RuO2–Ti Electrode-Assisted Electro-Biodegradation for Enhanced Rhodamine B Elimination Subramani Abilaji, Jayaraman Narenkumar, Manickam Sivaraman Nandini, Praburaman Loganathan, Sandhanasamy Devanesan, Mohammad Ahmad Wadaan, Zhen Fang, Aruliah Rajasekar Water Environment Research, 2026 Electro‐oxidation (EO) is a rapid and effective method for the elimination of organic and inorganic pollutants from wastewater. In this study, the titanium‐based mesh electrodes Ti/TiO 2 –RuO 2 were used for the removal of rhodamine B (RhB) azo dye in simulated water by the treated EO and EO‐treated biodegradation (EO and BD) with 20 mA/cm −2 direct current applied for the EO system, and the color removal was measured by UV‐spectrophotometer. The chemical oxygen demand (COD) was greatly reduced to 78% in the EO‐treated and 93% in the EO‐treated biodegradation sample, respectively, and the decolorization was accomplished in 30 min in 10 ppm. The biodegradation data verify that the bacterial strain used both organic and inorganic materials. TOC (total organic carbon) in EO and EO with biodegradation were 57.2% and 86.7%, respectively. It confirms that the EO with biodegradation effectively removes RhB and aids in complete mineralization. Fourier transform infrared spectroscopy (FTIR) confirms the functional groups cleaved during the process HRMS concluded that the intermediate products NH, C–N, and C=O were generated during EO with biodegradation. The calculated toxicity of LC50 and EC50 values of RhB was observed in RhB 6 (100<) in water for fish, daphnid, and green algae. The toxicity study confirms that the majority of intermediates from EO and BD were scarcely harmful. Overall, this study concludes that RhB was effectively degraded by the EO and mineralized by the BD, and this combined treatment plays a vital role in the remediation of pollutants in the wastewater effluent treatment plant.
