Microalgae can be exposed to a gradual copper (Cu) increase over wide concentration range in the environment, but most studies focus on punctual increases. This research investigates effects of quasi-continuous Cu exposure Kirchneriella obesa, providing new insights thresholds healthy and unhealthy cellular responses. Photosynthesis, cell density, biomolecules were measured at 20 free levels, from environmental toxic (3x10−9 4 x 10−5 mol L−1). Using nonlinear Bayesian regression models, we established mathematical functions describing relationship between measurements level computed credibility intervals for curves. Our findings revealed two distinct physiological response patterns dependent variable. Growth rate gradually decreased with increase, whereas total proteins carbohydrates increased. A steep transition condition was present photosynthetic variables, others exhibited variation. The Cu2+ triggering these changes differed, signalizing varying susceptibility. sensitive variables rETRmax (120 50 μmol e− m−2 s−1) Ek (180 80 photons decrease 6.5 10−8 5 10−7 L−1 Cu2+.

Abstract This study investigates the potential of Tetradesmus obliquus for lipid accumulation under heavy metal stress and evaluates it’s aviability biodiesel production. We surveyed how different concentrations metals, including manganese (Mn), cobalt (Co), zinc (Zn), influence carbohydrate & protein, yield, fatty acid profiles T. cultures. Our results demonstrated that while content increased stress, extent was highly dependent on type concentration. Notably, algal culture treated with 0.04 mM Co²⁺ showed highest accumulation. Treatment 0.3 Zn²⁺ resulted in proportion saturated acids (SFA). The Relative Enrichment Efficiency Coefficient (REEC) analysis 0.07 led to stimulation. Additionally, GC-MS revealed monounsaturated (MUFA) several conditions. exposure specific metals can significantly enhance alter , which are crucial improving quality. implications these findings suggest metal-induced could be a feasible approach enhancing sustainable production, T.obliquus is promising candidate future

The contamination of water by heavy metals is among the main ecological challenges society due to industrialization and urbanization. To overcome this issue, various treatment processes have been developed. Phycoremediation considered a promising strategy offering advantages in terms cost-effectiveness. present work aims investigate cellular responses an isolated green microalga strain (Chlamydomonas sp.) chromium (Cr) copper (Cu) exposure single bimetallic systems. At ½ IC50 concentration, metal removal efficiencies were reported: up 58.11 ± 0.979% for Cu 41.4 0.870% Cr When both combined, efficiency improved 57.71 0.832%, whereas showed minimal variation, reaching 58.43 1.059%. Furthermore, appeared negative effect on cell growth photosynthetic pigment accumulation. An enhancement lipid content microalgae cells after and/or exposure, particularly C14:0, C16:0, C20:0, C18:0, C16:1, C18:1, C20:1, as well polysaccharides, was detected, protein decreased. FTIR analysis that several functional groups could be involved phycoremediation process.

Genetic and biotechnological developments have made it possible to apply synthetic biology approaches new classes of microbial hosts, such as photosynthetic microalgae. A biosensor is a device that transforms biological answer into an electrical signal. These devices the potential be used in wide range applications, including environmental water quality monitoring. In biosensing microalgae been widely bioreceptors due their lower susceptibility physiochemical changes, well being medical, environmental, industrial, commercial fields. To overcome limitations conventional analytical techniques, technologies are introduced based on integrating different types microorganisms, microalgae, build biosensors. Detecting pollutants one main applications Our study highlights advantages disadvantages using produce biosensors technology for detecting wastewater heavy metals.
