“…One of the most widely used solvents for the extraction of lipids from microalgae for producing biodiesel is hexane. , However, surprisingly, the use of hexane in the one-pot cell wall disruption and extraction resulted in a slightly lower extraction yield and significantly lower astaxanthin recovery compared to that in the other solvents. This can be attributed to the low solubility of the extract in hexane .…”

The extraction of diverse thermolabile but highly value-added chemicals entrapped in the robust cell wall of algal biomass has remained a remarkable challenge. This study investigated the one-pot, simultaneous cell wall disruption and extraction of bioactive astaxanthin from the cysts of Haematococcus pluvialis. During the extraction, wet grinding in the presence of ethanol caused intimate contact of the solvent with the ruptured cells, resulting in almost complete astaxanthin recovery of 31.6 mg/g of dried H. pluvialis (>99% recovery) and a significantly high extraction yield of 46.9 wt % at room temperature (around 22 °C) and atmospheric pressure in a very short time (≤30 min) under a mild milling condition (≤200 rpm). The one-pot method allowed the use of other types of generally recognized as safe solvents such as acetone, ethyl acetate, hexane, and isopropyl alcohol. The antioxidant test indicated that the crude extracts were highly active in scavenging radicals. Thus, our one-pot method was an ecofriendly and economical extraction approach for the complete recovery of astaxanthin in a simple, rapid, low-temperature, and low-pressure manner that minimized the energy required for astaxanthin extraction and suppressed its degradation.

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.

Urbanization is a revolutionary and necessary step for the development of nations. However, with development emanates its drawback i.e., generation of a huge amount of wastewater. The existence of diverse types of nutrient loads and toxic compounds in wastewater can reduce the pristine nature of the ecosystem and adversely affects human and animal health. The conventional treatment system reduces most of the chemical contaminants but their removal efficiency is low. Thus, microalgae-based biological wastewater treatment is a sustainable approach for the removal of nutrient loads from wastewater. Among various microalgae, Tetraselmis sp. is a robust strain that can remediate industrial, municipal, and animal-based wastewater and reduce significant amounts of nutrient loads and heavy metals. The produced biomass contains lipids, carbohydrates, and pigments. Among them, carbohydrates and lipids can be used as feedstock for the production of bioenergy products. Moreover, the usage of a photobioreactor (PBR) system improves biomass production and nutrient removal efficiency. Thus, the present review comprehensively discusses the latest studies on Tetraselmis sp. based wastewater treatment processes, focusing on the use of different bioreactor systems to improve pollutant removal efficiency. Moreover, the applications of Tetraselmis sp. biomass, advancement and research gap such as immobilized and co-cultivation have also been discussed. Furthermore, an insight into the harvesting of Tetraselmis biomass, effects of physiological, and nutritional parameters for their growth has also been provided. Thus, the present review will broaden the outlook and help to develop a sustainable and feasible approach for the restoration of the environment.
