To determine the suitable temperature of and total lipid content and fatty acid composition in six strains of Chrysophyta and provide a scientific basis for its comprehensive utilization and development. The effects of temperatures on the growth were studied and their total lipid content and fatty acid composition were analyzed. The results showed that the most suitable growth temperature range of I. galbana (Tahitianstrain) H29 was 25 ~ 30 ℃, I. galbana 3011 was 25 ~ 30 ℃, I. galbana 3010 and I. zhanjiangensis were 25 ~ 35 ℃, I. galbana 8701 was 15 ℃, and I. galbana (daxidi) was 20 ~ 25 ℃. There were significant differences in total lipids and fatty acids contents in six strains of Chrysophyta. The contents of total lipids in the six strains of Chrysophyta were 17.47%~29.73%. Seventeen kinds of fatty acids were detected in six Chrysophyta, PUFAs accounted for 34.64%~57.03% of the total fatty acids. DHA accounted for 12.96 ~ 21.54%.

With the rapid development of intensive mariculture, lots of mariculture wastewaters containing residual feed and excrements are discharged into marinelands, leading to coastal pollution. Recently, the environmental problems caused by the discharge of mariculture wastewater have been paid much attention, as have other breeding industries in China. In fact, organic solid waste accounts for most of the pollutants and can be reduced by precipitation or filtration technologies, after which the supernatant can be easily treated by ecological methods. Some national guidelines and relevant local standards have been issued to strictly control the mariculture wastewater, but there are still few effective technologies for mariculture wastewater treatment due to its high salinity and extremely low pollutant concentration. This paper aims to propose feasible pollution control methods of mariculture wastewater according to the wastewater characteristics from different mariculture modes. For raw ammonia-based wastewater, it should be sequentially treated by precipitation, nitrification and denitrification and ecological methods, which would target solid waste, organic carbon/nitrogen and phosphorus removal, respectively. For the nitrate-based wastewater, this just needs denitrification filters and ecological methods for nitrate and phosphorus removal. After an overview of pollution control strategies for different types and scales of industrial mariculture wastewater treatment, some challenges are also mentioned.

“…Temperature affects crucial enzyme-mediated metabolic reactions. [171] Depending on the strain, microalgae have an optimum temperature ranging from 15 to 50°C, beyond which growth declines due to denaturation of enzymes and instability of pigments. [172] Biochemical pathways for biosynthesis and accumulation of unsaturated and saturated fatty acids and lipids are susceptible to thermal variations.…”

The world population is ever increasing and so is the need to ensure food security. Food production needs to increase by about 70% within the next 40 years to cater for food consumption. Moreover, with increasing collective consciousness toward food supplementation for improving quality of health, the development of nutraceuticals has gained prominence in disease prevention, treatment, and overall health improvement. However, due to the constant controversial debate of food production for consumption against other uses, the search for better alternatives led to microalgae. Species such as Spirulina, Chlorella, Scenedesmus, and Dunaliella, among many others, are important sources of primary and secondary metabolites that play crucial roles in disease prevention and treatment. Understanding the significance of nutraceuticals and how microalgae can be used to produce those value-added molecules is necessary for any potential commercial exploitation. This review discusses the potential of microalgae to be exploited as promising sources of nutraceuticals. Here, essential biomolecules used as nutraceuticals are explored and their crucial roles in disease prevention, especially cancer, cardiovascular diseases, and strengthening the immune system. The composition of microalgae, which makes them suitable candidates to produce nutraceuticals, is discussed. Furthermore, the multifarious aspects of microalgae cultivation, in terms of cultivation systems and factors affecting biomass production and productivity regarding nutraceutical production, are reviewed. The multiple sustainable facets of microalgae culture, which can help in carbon sequestration, fast biomass production, and boosting health benefits, should interest stakeholders and potential commercial producers. Bioprocessing of microalgae for the extraction and purification of microalgae-based products is also reviewed, focusing on the key methods of pre-treatment, extraction, and purification of microalgal biomass.
