Comparing the toxicity of tungsten and vanadium oxide nanoparticles on Spirulina platensis. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:45067-45076. [PMID: 36697989 DOI: 10.1007/s11356-023-25461-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Accepted: 01/17/2023] [Indexed: 06/17/2023]
Abstract
The production and release of nanoparticles and their impacts on living organisms are among the most important concerns in the world. Spirulina platensis was chosen because of its ability to absorb more elements than other algae. Therefore, an experiment was conducted to improve the product quality of spirulina exposed to new type of nanoparticles. In this experiment, vanadium oxide nanoparticles (VNPs) and tungsten oxide nanoparticles (WNPs) were used at concentrations of 0, 0.001, 0.017, and 0.05 g/l. The measured indices such as protein percentage and concentrations of phycobiliproteins and carbohydrates were the most important parameters of spirulina. Results showed that the concentration of 0.001 g/l of VNPs significantly affected the amounts of protein and phycocyanin. It has also been observed that 0.001 g/l of WNPs significantly influenced the amounts of protein (5.3%) and phycocyanin (90%); however, WNPs at all concentrations increased the concentrations of protein and phycocyanin. A concentration of 0.05 g/l of WNPs increased phycocyanin content by 83% over the control. The examination of nanoparticles by spirulina showed that VNPs were more adsorbed by spirulina than WNPs. In general, VNPs were toxic to algae at concentrations of 0.017 and 0.05 g/l, but WNPs did not show any fatal toxicity.

Abstract
Selenium-binding proteins (SBPs) represent a ubiquitous protein family implicated in various environmental stress responses, although the exact molecular and physiological role of the SBP family remains elusive. In this work, we report the identification and characterization of CrSBD1, an SBP homolog from the model microalgae Chlamydomonas reinhardtii. Growth analysis of the C. reinhardtii sbd1 mutant strain revealed that the absence of a functional CrSBD1 resulted in increased growth under mild oxidative stress conditions, although cell viability rapidly declined at higher hydrogen peroxide (H2O2) concentrations. Furthermore, a combined global transcriptomic and metabolomic analysis indicated that the sbd1 mutant exhibited a dramatic quenching of the molecular and biochemical responses upon H2O2-induced oxidative stress when compared to the wild-type. Our results indicate that CrSBD1 represents a cell regulator, which is involved in the modulation of C. reinhardtii early responses to oxidative stress. We assert that CrSBD1 acts as a member of an extensive and conserved protein-protein interaction network including Fructose-bisphosphate aldolase 3, Cysteine endopeptidase 2, and Glutaredoxin 6 proteins, as indicated by yeast two-hybrid assays.

Abstract
This scientometric review and bibliometric analysis aimed to characterize trends in scientific research related to algae, photobioreactors and astaxanthin. Scientific articles published between 1995 and 2020 in the Web of Science and Scopus bibliographic databases were analyzed. The article presents the number of scientific articles in particular years and according to the publication type (e.g., articles, reviews and books). The most productive authors were selected in terms of the number of publications, the number of citations, the impact factor, affiliated research units and individual countries. Based on the number of keyword occurrences and a content analysis of 367 publications, seven leading areas of scientific interest (clusters) were identified: (1) techno-economic profitability of biofuels, bioenergy and pigment production in microalgae biorefineries, (2) the impact of the construction of photobioreactors and process parameters on the efficiency of microalgae cultivation, (3) strategies for increasing the amount of obtained lipids and obtaining biodiesel in Chlorella microalgae cultivation, (4) the production of astaxanthin on an industrial scale using Haematococcus microalgae, (5) the productivity of biomass and the use of alternative carbon sources in microalgae culture, (6) the effect of light and carbon dioxide conversion on biomass yield and (7) heterotrophy. Analysis revealed that topics closely related to bioenergy production and biofuels played a dominant role in scientific research. This publication indicates the directions and topics for future scientific research that should be carried out to successfully implement economically viable technology based on microalgae on an industrial scale.

Abstract
In this study, the use of pH shock to improve astaxanthin synthesis in Haematococcus lacustris was investigated. It has been found that pH shock (pH = 4.5, 60 s) imposes stress in the cells and induces physiological changes, which result in astaxanthin accumulation. The optimal acid-base combination of pH shock was H2SO4-KOH, which increased the astaxanthin content per cell to 39 ± 6.92% than those of the control. In addition, pH shock can be applied simultaneously with the other inductive strategies such as high irradiance and carbon source supply. When high irradiance was applied simultaneously with pH shock, astaxanthin yield was increased 65 ± 0.541% than control. In addition, astaxanthin content per cell was increased 105 ± 6.66% than those of the control, with the concomitant application of carbon source addition with pH shock. Herein, these novel findings provide a useful technique for producing astaxanthin using H. lacustris.

Abstract
Bicarbonate has been considered as a better approach for supplying CO2 to microalgae cells microenvironments than gas bubbling owing t°Cost-effectiveness and easy operation. However, the β-carotene production was too low in Dunaliella salina cultivated with bicarbonate in previous studies. Also, the difference in photosynthetic efficiency between these tw°Carbon sources (bicarbonate and CO2) has seldom been discussed. In this study, the culture conditions, including NaHCO3, Ca2+, Mg2+ and microelement concentrations, were optimized when bicarbonate was used as carbon source. Under optimized condition, a maximum biomass concentration of 0.71 g/l and corresponding β-carotene content of 4.76% were obtained, with β-carotene yield of 32.0 mg/l, much higher than previous studies with NaHCO3. Finally, these optimized conditions with bicarbonate were compared with CO2 bubbling by online monitoring. There was a notable difference in Fv/Fm value between cultivations with bicarbonate and CO2, but there was no difference in the Fv/Fm periodic changing patterns. This indicates that the high concentration of NaHCO3 used in this study served as a stress factor for β-carotene accumulation, although high productivity of biomass was still obtained.

Abstract
Microalgae are a source of numerous compounds that can be used in many branches of industry. Synthesis of such compounds in microalgal cells can be amplified under stress conditions. Exposure to various metals can be one of methods applied to induce cell stress and synthesis of target products in microalgae cultures. In this review, the potential of producing diverse biocompounds (pigments, lipids, exopolymers, peptides, phytohormones, arsenoorganics, nanoparticles) from microalgae cultures upon exposure to various metals, is evaluated. Additionally, different methods to alter microalgae response towards metals and metal stress are described. Finally, possibilities to sustain high growth rates and productivity of microalgal cultures in the presence of metals are discussed.

Metabolic switching: synergistic induction of carotenogenesis in the aerial microalga, Vischeria helvetica, under environmental stress conditions by inhibitors of fatty acid biosynthesis.

Abstract
OBJECTIVES To investigate the roles of fatty acid biosynthesis in carotenogenesis in the high-lipid accumulating aerial microalga Vischeria helvetica KGU-Y001, we cultured algal cells with fatty acid biosynthesis inhibitors. RESULTS Under nitrogen-deficient, high-light (200 µmol photons m(-2) s(-1)) conditions, the alga accumulated 6.2 mg carotenoids g(-1) dry weight cells (DWC) after 1 week of culture. The total fatty acid content increased gradually, and reached 290 mg g(-1) DWC after 9 weeks. When algal cells were cultured with a fatty acid biosynthesis inhibitor (molinate) under nitrogen-deficient, high-light conditions for 1 week, carotenoid accumulation was synergistically increased to 2.4 times that in algal cells cultured without the inhibitor in nitrogen-deficient, low-light conditions (40 µmol photons m(-2) s(-1)). The synergistic induction of carotenogenesis was suppressed by an inhibitor of c-jun N-terminal kinase, a mitogen-activated protein kinase-like protein. CONCLUSION In a commercial context, carotenoid production could be increased by using fatty acid biosynthesis inhibitors to redirect metabolic flux to carotenoid biosynthesis instead of fatty acid synthesis.
