Abstract:
Bio-based fermented products have recently become increasingly important for both human health and sustainability due to the growing interest in healthy sustainable diets. In this study, spirulina was used as a substrate for the cultivation of Lacticaseibacillus rhamnosus 23.2 in a 3 L bioreactor and emphasized the evaluation of the potential health effects of the obtained bioactive products. The antioxidant potential of bioactive products has been extensively studied using assays like DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)) radicals, demonstrating its capacity to scavenge free radicals and mitigate oxidative stress. MTT and cell migration (scratch) assays reduced viability of Caco-2 cells and hindered cell migration cancer cells FS compared to unfermented spirulina (unFS) revealed that FS significantly reduced cell viability and migration in a dose-dependent manner, with the strongest effects observed at 5X dilution. In contrast, unFS showed weaker bioactivity. These findings highlight fermentation as a promising biotechnological approach to enhance the functional properties of natural compounds for cancer prevention and treatment. To summarize, the current study revealed that the potential of spirulina biomass to be a suitable media substrate for L. rhamnosus 23.2 strain. These findings will provide awareness toward milestone the health and food sector industrialization of FS products.
