The production of bioactive products from microalgae biomass with efficient and environmentally friendly technologies is a field great research interest. present work focuses on the recovery high-added value components Chlorella vulgaris through microwave-assisted extraction (MAE) aq. ethanol 90% v/v. effect temperature (40–60 °C), duration (5–25 min), solvent-to-biomass ratio (20–90 mLsolv/gbiom), microwave power (300–800 watts) was investigated regarding yield, extract’s chlorophyll, carotenoid phenolic content, antioxidant activity. MAE optimization at 60 °C, 300 watts, 14 min, 22 mLsolv/gbiom led to 11.14% w/w 63.36 mg/gextr total chlorophylls, 7.06 selected carotenoids astaxanthin, lutein β-carotene, 24.88 carotenoids, 9.34 mgGA/gextr phenolics, 40.49 mgextr/mgDPPH IC50 (antioxidant activity indicator). Moreover, conventional solid-liquid (SLE) v/v, supercritical fluid (SFE) CO2, as well SFE cosolvent addition (10% ethanol), were also performed for comparison purposes. results revealed that SLE presented highest yield. However, non-conventional methods extracts competitive or even better quality under significantly shorter duration.

As the global population continues to grow, demand for dietary protein is rapidly increasing, necessitating exploration of sustainable and nutritious sources. Algae has emerged as a promising food source due their high value ingredients such proteins, well environmental sustainability abundance. However, knowledge gaps surrounding recommendations applications restrict algae’s utilization viable source. This review aims address these by assessing suitability both microalgae macroalgae alternative/complementary sources exploring potential in products. The first section examines algae major analyzing composition bioavailability key components algal biomass, including lipids, fiber, micronutrients. Secondly, biological effects algae, particularly impact on metabolic health are investigated with an emphasis available clinical evidence. While evidence reveals protective glucose lipid homeostasis anti-inflammatory properties, further research required understand longer-term consuming protein, isolates, concentrates health, metabolism. then explores proteins applications, ways overcome sensory limitations, dark pigmentation, taste, odor, order improve consumer acceptance. To maximize valuable sector, future should prioritize production more acceptable biomass explore new advances sciences technology improved Overall, this paper supports utility healthy ingredient widespread use production.

Microalgae are a source of wide variety commodities, including particularly valuable pigments. The typical pigments present in microalgae the chlorophylls, carotenoids, and phycobiliproteins. However, other types pigments, family water-soluble polyphenols, usually encountered terrestrial plants, have been recently reported microalgae. Among such microalgal many flavonoids yellowish hue, used as natural textile dyes. Besides being colorants, for example food or cosmetic industry, also possess bioactive properties, making them functional nutraceutical pharmaceutical agents. Each type pigment, with its own chemical structure, fulfills particular biological functions. Considering both eukaryotes prokaryotes, some species within four most promising groups (Cyanobacteria, Rhodophyta, Chlorophyta Heterokontophyta) distinguished by their high contents specific added-value To further enhance pigment during autotrophic cultivation, review is made main related strategies adopted last decade, light adjustments (quantity quality, duration photoperiod cycle), regard to mineral medium characteristics (salinity, nutrients concentrations, presence inductive chemicals). In contrast what observed growth-related accumulation non-photosynthetic (polyphenols secondary carotenoids) requires stressful conditions. Finally, enrichment possible two new cutting-edge technologies, via application metallic nanoparticles magnetic fields.

Type 2 diabetes mellitus (T2DM) is an intricate disease correlated with many metabolic deregulations, including disordered glucose metabolism, oxidative stress, inflammation, and cellular apoptosis due to hepatic gluconeogenesis aberrations. However, there no radical therapy inhibit disturbances yet. We thus sought probe the effectiveness uncover potential mechanism of quercetin (QCT) silk sericin (SS) in mitigating hyperglycemia-induced disorder, which remains obscure. Administration QCT SS diabetic male albino rats markedly restored levels glucose, insulin, advanced glycation end-products (AGEs), liver function enzymes, alpha-fetoprotein (AFP), globulin, glycogen, addition carbohydrate metabolizing enzymes comparison rats. Furthermore, treatment modulated malondialdehyde (MD), reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), peroxidase (GPx), nitric oxide, tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), serum interleukin-6 (IL-6) cyclooxygenase-2 (COX-2), implying their safeguarding cells against impairment inflammation. Remarkably, treatments led upregulation expression phosphatidylinositol 3-kinases (PI3K), phospho-Akt (p-Akt), forkhead box-O1 (FOXO1) genes tissues compared rats, orchestrating these singling pathways for curtailing hyperglycemia pernicious consequences tissues. Importantly, immunohistochemical investigations exhibited downregulation caspase-3 treated animals. Beyond that, histopathological results demonstrated notable correlations biochemical findings. Interestingly, silico supported vivo findings, showing binding affinities PI3K, GPx, TNF-α proteins. These imply that could mitigate stress inflammation regulate revealed greater molecular interactions studied proteins than SS. Overall, our emphasize have significant therapeutic effects on attenuating gluconeogenesis, superior effectiveness.
