    ASSESSING POLLUTANT SORPTION EFFICIENCY OF MODIFIED AND UNMODIFIED BIOCHAR WITH BACILLUS CEREUS ON CONTAMINATED LAKE WATER: IMPLICATIONS FOR ORYZA SATIVA SEEDLING AND ARTEMIA FRANCISCANA LARVAE VIABILITY
    (Springer Link, 2023-10-02) Mathiyazhagan, Narayanan; Ramesh, Subramani; Sabariswaran, Kandasamy
    This study evaluated the efficacy of biochar in removing pollutants from a polluted lake. Biochar, both with and without Bacillus cereus, was assessed for its sorption potential. The treated water samples were analyzed for toxicity using Oryza sativa and Artemia franciscana larvae. The lake water exceeded permissible limits for pH, turbidity, dissolved oxygen (DO), chemical oxygen demand (COD), biological oxygen demand (BOD), and various metals. The 10-day biosorption study with different treatment groups (MB, UMB, MBB, UMBB, and BC) revealed that the MBB group exhibited remarkable pollutant sorption potential. It achieved pollutant removal percentages of 33.35% for Cd, 15.73% for As, 26.21% for Cr, 32.72% for Pb, 32.81% for Zn, 23.58% for Cu, 5.44% for Cl, 22.01% for Ni, 28.2% for Hg, and 4.19% for SO42−. MBB-treated lake water showed no toxicity, confirming pollutant removal by metal-tolerant Bacillus cereus in modified biochar.

    RESVERATROL-LOADED Β-LACTOGLOBULIN NANOFIBRILS TO PREVENT ENZYMATIC BROWNING ON SLICED APPLE
    (Applied Food Biotechnology, 2022) Praveetha, Senthilkumar; Vladimir, Shavrov; Petr, Lega; Ramesh, Subramani
    : Resveratrol is a polyphenol with nutraceutical health benefits used as anticancer, antioxidant and anti-inflammatory with cardio protective effects. However, resveratrol lacks solubility and bioavailability and is affected by UV light, which decrease its use in food industries. It is possible to overcome these problems by loading resveratrol with appropriate biomaterials. Beta-lactoglobulin is known to form well-defined nanofibrils with various uses. The objective of this study was to use β-lg nanoscaled fibrils to increase bioavailability of resveratrol as well as preserving freshness and preventing enzymatic browning of sliced apples
