“…Both chlorophyll a and b were clearly identified, along with their known epimeric isomers (Asker et al 2018;Patias et al 2017;Rivera et al 2014).

Microalgae are a diverse group of photosynthetic eukaryotic organisms that are widely distributed globally. They are prolific sources of highly valuable compounds with fascinating chemical structures. Due to their balanced nutritional compositions and health benefits, they are increasingly being used as functional food ingredients. Carotenoid‐based pigments and polyunsaturated fatty acids (PUFAs) are examples of high‐value nutrients that can be accumulated abundantly in microalgae. Here, the effects of potassium chloride‐induced stress on the productions of lipids and carotenoids in the green microalga of the Chlorococcaceae family were investigated. Under normal BG11 medium, this green microalga strain TISTR 9500 accumulated high levels of PUFA and primary carotenoid lutein. Stress tests revealed that KCl enhanced and modulated lipid and carotenoid accumulation levels. The liquid chromatography‐tandem mass spectrometry (LC‐MS/MS) analysis revealed that secondary carotenoids astaxanthin and canthaxanthin were robustly produced under KCl stress with the similar content of lutein. Further, this stress led to a significant increase in the total FA amount with the higher proportion of unsaturated FA than saturated FA. Thus, this green microalga could be an attractive and alternative natural biosource for canthaxanthin and astaxanthin, as well as for functional lipids.

Aims Cyanobacteria may have considerable effects on community functioning, mostly because they produce various metabolites that adversely affect other organisms. Here we synthesized existing knowledge about the effects of toxic cyanobacteria on the germination and growth of terrestrial plants. We also aimed to test the chemical effects of a Nostoc (Cyanobacteria) extract on the germination and growth of species of alkali habitats to investigate whether cyanobacteria can alter community structure and diversity via affecting the establishment success of plants. Location Cyanobacterium colonies from the Hortobágy National Park, east Hungary; indoor experiments at the University of Debrecen, Hungary. Methods To review the effects of toxic cyanobacteria on terrestrial plants, we conducted a literature search. To test these effects on native plants, field‐collected Nostoc colonies were used to prepare a cell‐free water extract, and treatments (watering with Nostoc extract and watering with tap water) were tested on 3 × 100 seeds of nine alkali grassland species. After 5 wk, seedling number, seedling length and fresh and dry weights were measured. Results We collected data on the effects of cyanobacteria on 27 species, but they were mostly focused on crops irrigated with cyanobacteria‐containing water, not on floras native to natural ecosystems. In the germination experiment species identity and treatment had a significant effect on almost all variables, but their interaction only affected germination rate and fresh weight. Fresh weight decreased significantly only in the invasive Hordeum jubatum, but germination rate decreased significantly in five species. Conclusions Based on our findings, terrestrial cyanobacterium colonies can affect the establishment success of grassland plants, through which they may be important in determining which species can be incorporated into the community. Thus, cyanobacteria might play an important role in shaping diversity, species composition and the structure of natural plant communities.

“…Dunaliella salina is a halophilic microalga, which has a high ability for beta carotene accumulation. It can generate beta carotene when exposed to stress conditions, such as high light intensity, high temperature, enhanced salinity levels, and nutrient deficiency . The presence of beta carotene protects the cells from photooxidative damage and against osmotic pressure.…”

Thus, D salina can be introduced into wastewater treatment processes and also as an alternative feedstock to obtain high yields of biomass, while facilitating further beta carotene production.…”

Summary Extensive amounts of organic and inorganic substances are discharged into the environment, and they have been ascribed to a number of anthropogenic activities including agriculture, industry, and domestic processes. Microalgae, as a promising alternative feedstock for bioenergy production, have advantages in the uptake of nutrients from wastewater for biomass production. This study assessed the feasibility of mass cultivation of microalgae in controlled environment tertiary treated municipal wastewater. Dunaliella salina (D salina) was selected for its high beta carotene generation capacity and being a halophilic species to protect our freshwater resources further in wastewater remediation. Nutrient analyses indicated that D salina can significantly remove nitrate, ammonia, and phosphorus from municipal wastewater in the range of 45% to 88%. Among all combinations studied, the optimal algal growth was observed at 30 ppt salinity level, with a 75% wastewater concentration (3:1 ratio of wastewater and saline water mixture—the growth medium). The findings concluded that D salina has great capacity for nutrient uptake while providing high‐value bioproducts. It can therefore be recommended as a potential candidate species that could be used in wastewater treatment systems coupled with high‐value bioproducts production.
