    Abstract The outbreak of the coronavirus disease of 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 that has created huge trepidation worldwide, has a mortality rate of 0.5% to 1% and is growing incessantly. There are currently no therapies and/or vaccines that may help abate this viral disease, but the use of masks and social distancing can limit the spread. Boosting immunity has been a simple way to resist viral infection and limit fatalities. In this context, the use of nutraceuticals appears to be a potential panacea. The ability of algae-based nutraceuticals, mainly Spirulina, to boost immunity against viral diseases has already been reported clinically. Spirulina-based nutraceuticals boost the adaptive and innate immunity, and bioactive compounds, such as angiotensin-converting enzyme (ACE) inhibitor peptides, phycobiliproteins, sulfated polysaccharides, and calcium-Spirulan, can serve as antiviral agents. The presence of these molecules indicates its potential role in resisting infection and COVID-19 disease progression. This review focuses on the potential role of algal nutraceuticals as immune boosters to combat the human coronavirus and other viral diseases. The potential use of Spirulina-based nutraceuticals for combating COVID-19, its mechanism, and future directions have also been discussed.

    Abstract Remediation of the antiretroviral (ARV) drug, nevirapine (NVP) has attracted considerable scientific attention in recent years due to its frequent detection and persistence in aquatic environments and potential hazards to living organisms. Algae-based technologies have been emerging as an environmentally friendly option for the removal of pharmaceutical compounds, but their ARV drug removal potential has not been fully explored yet. This study aimed to explore the ecotoxicity and removal potential of NVP by two microalgal species, Coelastrella tenuitheca and Tetradesmus obliquus.

    Abstract The present investigation was aimed towards analyzing the potential of consortia of native filamentous microalgal strains (MC2), native unicellular microalgal strains (MC3), and selected microalgae from germplasm (MC1) in terms of nutrient removal, water quality improvement, and biomass production using primary treated sewage water. Highest NO₃-N (90� %) and PO₄-P (97.8� %) removal was obtained with MC2-inoculated sewage water. Highest decrease in total dissolved solids to 806 from 1,120� mg L⁻¹ and highest increase in dissolved oxygen of 9.0 from 0.4� mg L⁻¹ were obtained using MC2-inoculated sewage water on the sixth day. The biomass production was also highest in MC2 (1.07� g L⁻¹) followed by MC1 and MC3 (0.90 and 0.94� g L⁻¹, respectively) on the sixth day. The consortium of filamentous strains from native environment not only proved promising in nutrient removal efficiency but also led to enhanced biomass. The present study highlighted the utility of such a consortium for sewage wastewater treatment and the promise of sewage water as a growth medium for biomass production.

    Abstract A biphasic nutritional strategy was employed for enhancing lipid accumulation in the three selected microalgae Chlorella sp. MIC-G4, Chlorella sp. MIC-G6 and Scenedesmus sp. MIC-G8, involving supplementation with different nitrogen sources (NaNO3, KNO3, urea and (NH4)2CO3), followed by their limitation. NaNO3 was found to be the best for enhancing lipid accumulation. Palmitic, linoleic and alpha linolenic acids were the most abundant fatty acids. MIC-G6 recorded the highest content of α- linolenic acid (43.7% of total fatty acid) after 32d growth in nitrogen rich medium and 36.0%, after 24d growth in nitrogen rich medium followed by 8d in nitrogen limited medium. An enhancement of 40–50% in lipids on dry weight basis was recorded in Chlorella sp. MIC-G4 and Scenedesmus sp. MIC-G8, in the treatment involving 24d growth in nitrogen rich medium, and 8d in nitrogen limited medium. An abundance of 92–97% (% of total fatty acids) of C16–C18 fatty acids was recorded. Our study illustrates the promise of MIC-G4 and MIC-G8 as a source of lipids, triggered by the biphasic mode of cultivation, and the need to undertake in-depth gene expression profiling to enhance further the lipid accumulation.
