“…The Bligh and Dyer method is used for total lipid extraction and purification with methanol and chloroform as solvents, and water as cosolvent [26]. A number of works have been reported in the literature using the Bligh and Dyer method for the extraction of lipids [22,[27][28][29][30] and modified forms of this method have also been used [31][32][33][34][35]. Lee et al [31] evaluated the performance of five different solvent systems such as chloroform/methanol (2:1, v/v); hexane/ isopropanol (3:2, v/v); dichloromethane/methanol (1:1, v/v); dichloromethane/ethanol (1:1, v/v) and acetone/dichloromethane (1:1, v/v) via bead beating of Botrycoccus braunii biomass.…”

“…For this reason, efficient extraction and transesterification in addition to cultivation and harvest of microalgae are the key processes in microalgal biofuel production. To improve production yield, various extraction methods have been reported including conventional solvent (for example, hexane) extraction, accelerated solvent extraction (using organic solvents at high pressures and temperatures above the boiling point) and supercritical fluid extraction (Cheng et al, 2011;Mouahid et al, 2013).…”

Global warming due to the accumulation of atmospheric CO 2 has received widespread attention in recent years. Although various CO 2 capture technologies have been proposed, using the captured CO 2 from power plants is increasingly popular because of concerns with regard to the safety of underground and ocean CO 2 storage. Various techniques related to utilization of CO 2 from the exhausted gas of power plants are discussed in this article. The existing and under-development technologies for CO 2 utilization in the world are briefly reviewed. Two categories, direct utilization of CO 2 and conversion of CO 2 to chemicals and energy products, are used to classify different forms of CO 2 utilization. Regarding the direct utilization of CO 2 , in addition to its use in soft drinks, welding, foaming, and propellants, as well as the use of supercritical CO 2 as a solvent, CO 2 capture via photosynthesis to directly fix carbon into microalgae has also attracted the attention of researchers. The conversion of CO 2 into chemicals and energy products via this approach is a promising way to not only reduce the CO 2 emissions, but also generate more economic value. Since CO 2 is just a source of carbon without hydrogen, a clean, sustainable and cheap source of hydrogen should be developed. This article reviews the literature on the production of biofuel from microalgae cultivated using captured CO 2 , the conversion of CO 2 with hydrogen to chemicals and energy products, and sustainable and clean sources of hydrogen, in order to demonstrate the potential of CO 2 utilization.

“…In order to produce biodiesel, lipids are extracted and transesterified. The robust cell wall of microalgae, however, makes lipid extraction difficult and a disruptive treatment of algal cells by microwaves or sonication prior to extraction was found to give higher yields of lipids [59,60].…”

“…Conventional lipid extraction methods base on ethyl acetate/methanol and chloroform, followed by acid or base catalysed transesterification with methanol in order to convert fatty acids into biodiesel [60][61][62]. However, the use of organic solvents for extraction is not only cost-intensive, but it raises concerns about the environmental benignity of biodiesel production.…”

Around 1.3 billion tonnes of food are wasted worldwide per year, which is originally produced under extensive use of energy and nutrients. Use of food waste as feedstock in biotechnological processes provides an innovative way to recover parts of the energy and nutrients initially spent on food production. By chemical and biological methods, food waste is hydrolysed to glucose, free amino nitrogen and phosphate, which are utilisable as nutrients by many microorganisms whose metabolic versatility enables the production of a wide range of products. Microalgae are particularly of interest as chemicals, materials and energy are obtainable from microalgal biomass after chemical and/or biological modifications. In this review, valorisation of food waste in biotechnological processes is presented as an additional option to green chemical technologies.
