Abstract:
Slaughterhouse blood is a valuable by-product since multiple bioactive compounds can be derived out of it. Its solid fraction consists mainly of hemoglobin, which is a good source of antimicrobial and antioxidant peptides that can be released by peptic hydrolysis. Nevertheless, this method has limitations such as low yield, expensive cost of enzyme process, and non-eco-friendly production (high energy consumption and chemical reagents requested). Amount the alternative green technologies for protein valorization, pulsed electric field (PEF) stands out since it allows modifying the physicochemi

Abstract:
Oleaginous yeasts may provide an alternative platform for the sustainable production of microbial lipids-derived biodiesel and other health promoting bioactive metabolites such as natural pigments. In this regard, traditional fermented foods are unique and untapped habitats for the isolation and characterization of oleaginous yeasts with beneficial properties. In this study, we analysed the yeast diversity from selected traditional fermented foods of Manipur and Mizoram, India and studied their oleaginous attributes for biodiesel production. 14 potential oleaginous yeasts were isolated using c

Abstract:
The use of natural products for healing purposes has gained great attention worldwide. Increased interest in certain plant products has been achieved mainly due to their ability to limit antibiotic resistance. Also, as the hypothesis that all biological processes at the cellular level are severely affected by the formation of free radicals has been confirmed, it is attempted to highlight some active principles in plants and their use as agents to counteract the oxidative process [1, 2]. This paper aims to demonstrate the antioxidant and antibacterial capacity of the alcoholic extracts from the

Abstract:
Ocimum basilicum L. is an aromatic plant in the family Lamiaceae with bioactive properties used since ancient times in traditional medicine. The active ingredients of basil essential oil can be used in perfumes, pharmaceuticals, medicine, cosmetics or spices. In this study, the essential oil of basil was obtained by hydrodistillation in the Clevenger continuous extractor. It was characterized by GC-MS and 53 constituent compounds were identified. The majority compounds were highlighted: linalool, 64,569%, p-allyl anisol, 5,163%, Eucalyptol, 3,745%, α-Cadinene, 3,510%. Kovats indices were calcu
