Freshwater algal species consortia exhibit optimal biomass and biodiesel production under calcium chloride and magnesium sulphate stress.

Microalgae have been pioneering microbial cell factories for sustainable bioenergy production and other high-value product extraction. The present study affirms using mixed algal species (MAS) as a consortium for escalated biomass yield and lipid production under different calcium chloride and magnesium sulphate concentrations toward biofuel production. Of the different concentrations of Ca and Mg concentrations tested, 75 mg/L of calcium and 125 mg/L of magnesium displayed maximal biomass yield, cell density, and biomass productivity.

Bio-Characterization and Liquid Chromatography-Mass Spectrometry Analysis of Exopolysaccharides in Biofilm-Producing Cyanobacteria Isolated from Soil Crust: Exploring the Potential of Microalgal Biomolecules.

Exopolysaccharide-producing cyanobacterial strains in biological soil crusts are described, in addition to their chemical properties and antioxidant and flocculation activities. The EPSs from Pudukkottai blackish biological soil crusts (PBBSCs) showed significant amounts of total soluble proteins (0.1687 mg/mL) and carbohydrates (0.

Optimization Study of the Capacity of as a Potential Bio-Remediator for the Bio-Adsorption of Arsenic (III) from Aquatic Environments.

This study examined the ability of the green microalgae to remove arsenic from aqueous solutions. A series of studies was conducted to determine the optimal conditions for biological arsenic elimination, including biomass amount, incubation time, initial arsenic level, and pH values. At 76 min, pH 6, 50 mgL metal concentration, and 1 gL bio-adsorbent dosage, the maximum removal of arsenic from an aqueous solution was 93%.

Anticancer and Cytotoxicity Activity of Native and Modified Black Rice Flour on Colon Cancer Cell Lines.

This study is intended to evaluate the cytotoxicity of native and dual-modified black rice flour against the colon cancer cell line (HCT116) and mouse embryo cell line (3T3-L1) by using the MTT assay. The modification techniques applied to prepare rice flour samples were enzymatic modification and heat moisture treatment. In this study, the IC50 of native black rice flour and modified black rice flour was 255.

Biosynthesis of silver nanoparticles by using of the marine brown alga and their characterization.

Silver nanoparticles (AgNPs) are gaining considerable importance due to their attractive physicochemical properties for many applications. In the present study, (Ag NPs) were synthesized by the reduction of aqueous solutions of silver nitrate (AgNO) with powder and solvent extracts of (brown algae). The obtained nanoparticles exhibited high stability, rapid formation of the biogenic process (2 min -3 h), small size (49.
