Microalgae are promising sources of valuable carotenoids like β-carotene and astaxanthin with numerous health benefits. This review summarizes recent studies on producing these in microalgae under different salinity light-intensity conditions, which key factors influencing their biosynthesis. The carotenoid biosynthesis pathways microalgae, involving the methylerythritol phosphate pathway chloroplasts, described detail. effects high light stress stimulating accumulation species Haematococcus pluvialis Chromochloris zofingiensis synergistic impact discussed. Similarly, covers how induce production Dunaliella salina other microalgae. diverse health-promoting properties β-carotene, such as antioxidant, antiinflammatory, anticancer activities, highlighted. Strategies to improve yields through environmental stresses, two-stage cultivation, genetic engineering, metabolic engineering approaches evaluated. Overall, this highlights advancements reporting microalgal capability produce level 31.5% increase productivity reaching 18.1 mg/L/day lacustris. It also explores novel biotechnological strategies, including CRISPR-Cas9, for enhancing yield.

The interest in biogas, which is a renewable energy source, has been growing rapidly recent years. It prohibited to discharge digestates resulting from the biogas process into environment, and they have very high pollutant load. In this study, basal media (BBM) was added five different liquid (BLD). Microalgae tolerant their own environment adapted an increase observed cell densities. As result, microalgal biomass obtained, its potential for biodiesel, investigated by extracting oil obtained biomass. all groups, NH4 removal 99%. Chemical oxygen demand (COD) determined be range of 82–96%. When lipid production values were analyzed, it seen that most effective groups M4 M5. Based on estimated biodiesel properties, concluded are usable. Finally, BLD, sector, can converted biodiesel. research revealed (BLD 20% + BBM 80%) M5 40% 60%) treatments, had highest levels BLD among promising terms CO2 removal, microalgae yield, chemical potential.

The growing demand for surgical cotton in the healthcare sector has led to increased production southern Tamil Nadu, generating effluents that pose environmental risks due their chemical composition. Unlike conventional textile effluents, processing wastewater is distinct its lack of colour additive, but it exhibits high oxygen (COD) and contains significant inorganic pollutants, necessitating tailored treatment strategies. Despite extensive research on wastewater, effective solutions remain underexplored. This bridges this gap by exploring a novel synergic method, algae-bacterial symbiosis combined with photocatalytic degradation real effluent, order ultimately improve removal ability contaminants. general aim was study performance three continuous reactor, biological rector coupled biological-photocatalytic (CBPCR) reactor effluent during 30 days. efficacy measured observing rates nutrient, COD, microbial growth. It concluded CBPCR system successfully removed nitrate, phosphate, ammonia, COD 90%, 87%, 75%, 93% respectively. In particular, fostered vigorous growth both microalgae bacteria, as indicated total chlorophyll concentration 20.1 ± 0.91 mg/L dry cell weight 1.81 0.09 g/L. paper shows feasibility green, sustainable strategy such fills current practice industrial treatment.
