Developing countries like India are struggling with the continuous indiscriminate disposal of MSW due to rapid increase in the urbanization, industrialization, and human population growth. The mismanagement of MSW causes adverse environmental impacts, public health risks, and other socio-economic problems.

Anthocyanin-rich black wheat as a functional food for managing type 2 diabetes mellitus: a study on high fat diet-streptozotocin-induced diabetic rats.

: Type 2 Diabetes Mellitus (T2DM) is associated with insulin resistance, hyperglycemia, and hyperlipidemia. Anthocyanins, which are natural antioxidants, have been reported to manage T2DM-related complications. However, the potential of anthocyanin-rich black wheat as a functional food for managing diabetes remains unexplored.

Agro-industrial residue torrefaction to bio-coal: Its physico-chemical characterization and potential applications in energy and environmental protection.

Leveraging biofuel derived from biomass stands as a pivotal strategy in reducing CO emissions and mitigating the greenhouse effect. Biomass serves as a clean, renewable energy source, offering inherent benefits. However, despite its advantages, biomass encounters obstacles hindering its widespread industrial applications, including its relatively low calorific value, limited grindability, high water content, and susceptibility to corrosion.

The overuse of antibiotics has accelerated antibiotic resistance, and it is a significant global threat to public health. To combat the rising threat of drug-resistant microbes, antimicrobial photodynamic therapy (APDT) has emerged as a promising alternative therapeutic strategy. This study focuses on the synthesis of eco-friendly lignin-derived gold-titanium dioxide nanophotocomposites (L@Au-TiO NCs).

NGS-Based Metagenomics Depicting Taxonomic and Functional Insights into North-Western Himalayan Hot Springs.

Unlabelled: Hot springs have tremendous significance due to their divulging physiochemical features. In the recent past, metagenomics has emerged as a unique methodology to explore microbiota as well as new biocatalysts possessing advantageous biochemical properties from hot springs. In the present study, metagenomics has been employed for microbial diversity exploration and identification of genes involved in various metabolic pathways among two hot springs, Manikaran and Tatapani, located in Himachal Pradesh, India.

Microwave-assisted acid extraction of high-methoxyl kinnow () peels pectin: Process, techno-functionality, characterization and life cycle assessment.

The present study assessed the efficacy of kinnow peel pectin-acetic acid extraction using microwave heating at 110 °C, pH 2.2 for 10 min with a 1:2 ratio supernatant to ethanol for higher yield. The kinnow peel was freeze dried and grinded to fine powder for pectin extraction.

Development and Characterization of a Tunable Metal-Organic Framework (MOF) for the Synthesis of a Rare Sugar D-Tagatose.

D-tagatose is a valuable rare sugar with potential health benefits such as antiobesity, low-calorie, prebiotic, and anticancer. However, its production is mainly depending on chemical or enzymatic catalysis. Herein, a cobalt-based metal-organic framework (MOF) was developed at room temperature in an aqueous system using a self-assembly method.

Surface Acidic Species-Driven Reductive Amination of Furfural with Ru/T-ZrO.

Catalyst development for upgrading bio-based chemicals towards primary amines has increasingly attracted owing to their applications in the pharmaceutical and polymer industries. The surface acidic sites in metal oxide-based catalysts play a key role in the reductive amination of aldehydes/ketones involving H and NH; however, the crucial role of the type of surface acidic species and their strength remains unclear. Herein, this study exhibits the catalytic reductive amination of furfural (FUR) to furfurylamine (FUA) with Ru supported on tetragonal (Ru/T-ZrO) and monoclinic (Ru/M-ZrO) ZrO.

Combatting synthetic dye toxicity through exploring the potential of lignin peroxidase from Pseudomonas fluorescence LiP RL5.

Untreated release of toxic synthetic and colorful dyes is a serious threat to the environment. Every year, several thousand gallons of dyes are being disposed into the water resources without any sustainable detoxification. The accumulation of hazardous dyes in the environment poses a severe threat to the human health, flora, fauna, and microflora.

New Strategy for Browning Prevention in Apple Pomace Processing and Toxicity Tested in a Rodent Model.

Apple pomace (AP) is a byproduct of apple juice industries, which constitutes around 30% of the original fruit and rich in essential compounds like carbohydrates, phenolics, minerals, and dietary fibers.
