Sargassum-Derived Gold Nanoparticles for Biofilm Control: Innovative Sustainable Paint Coatings for Dairy Contact Surfaces Lavanya M, Srinivasan Krishnamoorthy, Baskaran N, Vignesh Sivanandham ACS Food Science and Technology, 2026 Biofilm formation on food contact surfaces is a significant threat to food safety in the dairy industry. This study presents an eco-friendly approach using gold nanoparticles synthesized from Sargassum sp. (S-AuNPs) to mitigate biofilms on SS-316 stainless steel and glass surfaces. Biofilm-forming bacteria, mainly Klebsiella and Enterobacter species, were isolated from dairy waste and confirmed via 16S rRNA sequencing; over 73% of strains showed high resistance to common antibiotics, highlighting the need for alternative solutions. S-AuNPs were thoroughly characterized by UV−vis, FTIR, SEM, EDAX, and XRD, revealing an average particle size of 48.7 nm and strong colloidal stability. Antioxidant assays demonstrated up to 49% radical scavenging activity at 100 μg/mL. Antibacterial tests showed inhibition zones ranging from 8 to 20 mm against resistant biofilm isolates, and synergy with methicillin increased inhibition zones further. Coating studies on SS-316 and glass coupons demonstrated up to 2.2 log reduction in biofilm biomass (from 6.48 to 4.27 log CFU/mL in Klebsiella and similar trends for Enterobacter ), with resin/S-AuNP and Apcomin/S-AuNP coatings offering the most effective biocidal performance. These results underscore the potential of Sargassum -derived gold nanoparticles as sustainable and effective biocidal coatings for dairy processing equipment, providing a viable alternative to traditional chemical sanitizers.
Batch and Continuous Biosorption Process and Its Scale-Up to Industrial Application S Aishwaryalakshmi, S. K. Sivashree, Srinivasan Krishnamoorthy, R Jagan Mohan, N Baskaran, S Vignesh Development of Agro Industrial Wastes as Adsorbent Materials Applications and Future Scope, 2026 The world’s rapid industrial growth and rising population have contaminated the environment with toxic metals and other pollutants, which are extremely dangerous to human health. Biosorption, the technique of using biological materials such as living or dead microorganisms as adsorbents to eliminate or retrieve a variety of materials, such as organic contaminants, heavy metals, and colors, is a flexible solution derived from aqueous solutions. The primary benefits of this procedure consist of its ease of usage, minimal sludge production, low nutritional requirements, low operating costs, great effectiveness, and biosorbent regeneration. The process of biosorption is affected by agitation speed, pH, temperature, and dose of the biosorbent. Batch biosorption and continuous biosorption are the two main methods for carrying out biosorption. These methods vary based on a number of criteria, including the operation’s size, the particular contaminants being targeted, and the infrastructure and resources that are available. The adaptability of biosorption is a distinctive feature, as both live and dead cells offer a wide range of possibilities and combinations, illustrating tremendous application flexibility. It is essential to overcome challenges in scaling up a biosorption process, such as adapting microbial biomass to an industrial environment in line with technical, economic, and regulatory aspects. Nonetheless, sustainable new generation biosorbents with high metal removal capacity are critical to upgrading them for industrial operations. This article summarizes the batch and continuous biosorption process and its scaling-up strategies for industrial applications, reassuring readers of its potential in various scenarios and inspiring optimism about its widespread application.
Numerical investigation on the virus transmission during sneeze, cough, and speech scenarios from an infected individual in an isolation room Naren Aadhithya R, Balamurugan K, Gobinath N, Adithya V, Vignesh S, Radha R Journal of Hazardous Materials Advances, 2025 Numerical simulation plays a crucial role in understanding and mitigating the airborne transmission of infectious aerosols in enclosed environments. Reducing airborne virus transmission in air-conditioned environments has become vital in ensuring occupant safety. This study uses computational fluid dynamics (CFD) to simulate virus dispersion in an indoor setup and assesses a negative pressure isolation room design. The system comprises a quarantine room and a common room, with a suction vent and pressure outlet installed in the quarantine area. A pressure differential prevents cross-room transmission while the suction vent captures airborne particles. The study evaluates virus emissions during sneezing, coughing, and speaking. Without intervention, particles linger for 20 s, 10.4 s, and 6.5 s respectively. With the proposed model, particles are cleared 11.25 s, 6.4 s, and 1.4 s sooner. Additionally, a 3 K temperature reduction within 5 s was observed, enhancing airflow effectiveness. The findings demonstrate that negative pressure environments can significantly reduce particle persistence and exposure risk. The present work could support the development of safer indoor spaces. Further studies could focus on scale the system to multi-room configurations and optimize energy consumption in long-term operations.
Synbiotic fermented barnyard millet drink: Exploring its nutritional profile, sensory attributes, and bioactive health potentials Bilna Joseph, Bhavadharani M, Nivetha S, Lavanya M, Jagan Mohan R, N Baskaran, S Vignesh Food Chemistry Advances, 2025 • This plant-based functional beverage addresses nutritional deficiencies. • Eight fermented drinks were developed using L. rhamnosus and S. cerevisiae . • Spirulina sp ., can be incorporated as a microbial fortificant in health drinks. • GC–MS analysis revealed rich bioactives present in these fermented drinks. The global market for functional beverages made from plant-based or non-dairy milk is rapidly growing. In developing tropical countries, plant-based food resources are insufficient to meet the protein needs of humans and animals. Millets, particularly barnyard millet, offer significant nutritional benefits due to their drought and pest resistance, high energy yield, and rich content of fiber, protein, iron, and zinc. This study developed eight health drink samples using barnyard millet and Spirulina sp., fermented with Lactobacillus rhamnosus and Saccharomyces cerevisiae . The protein content of bacterial fermented samples ranged from 1.39 % to 4.61 %, and yeast fermented samples from 2.52 % to 4.09 %. Carbohydrate content ranged from 5 % to 14.8 %, suitable for diabetics. The energy value ranked as LRFFD > LRFUFD > SCFFD > SCFUFD > SCFSP > LRFSP > LRFM > SCFM. Bacterial fermented samples had viscosities from 37.55 to 49.49 Pa.s., and fungal fermented samples from 37.55 to 49.59 Pa.s. GC–MS analysis identified oleic acid, which lowers cholesterol and reduces inflammation, and hexadecenoic acid, beneficial in managing Alzheimer's disease. Probiotics in the drinks support gastrointestinal health. Sensory evaluation showed that the LRFFD and SCFFD drinks had a good taste due to the incorporation of flavour.
Supercritical Fluid Extraction Of Phytochemicals From Plants Charu, Seba P. Shahir, E. Arunkumar, S. Vignesh, N. Baskaran Applications of Supercritical Fluid Extraction in Food Processing, 2025 Phytochemicals can be found in vegetables, beans, whole grains, fruits, seeds, and nuts. According to scientists, eating a diet high in phytochemical-rich plant foods may help to control various incidences that include cancer, stroke, high blood pressure, as well as other major illnesses including heart disease. In this review, the green extraction technology of such phytochemicals from plants that contain promising health-promoting effects is discussed. In the development of drugs and functional foods, determining the health benefits of phytochemicals and proper extraction methodology is critical. For extracting these phytochemicals from plant sources, various extraction procedures have been developed, including traditional and modern technologies. The commercialization of phytochemicals as bioactive molecules has prompted scientists to look toward more environmentally friendly, efficient, and cost-effective extraction methods based on a green extraction approach, as traditional extraction methods use solvents and require long extraction times. Supercritical fluid extraction is one such green technology, with numerous advantages over traditional, time-consuming, and tedious extraction procedures, including reduced solvent use, time and energy consumption, and increased recovery rates at a cheaper cost of operation. These extract the important bioactive chemicals with a higher degree of purity, ensuring that bioactive compounds perform as intended. This review describes the significance and classification of plant phytochemicals, instrumentation, and application of supercritical fluid extraction of phytochemicals from 318plant sources, and the advantages of supercritical fluid extraction over conventional techniques.
