“…Kojima and Zhang (1999) reported 50% lipid content obtained in photobioreactors supplemented with 1% CO 2 . A wide range of lipid content results has been obtained for various B. braunii strains and some with importance for biodiesel production were summarized in Tasić et al (2016). Although values of lipid content up to 80% has been reported (Li and Qin, 2005;Chisti, 2007), most of the values reported for B. braunii was in the range of 15 to 40% dry weight, which indicates the capability of the strains used herein.…”

ACOI 58 and ACOI 1257, two different Portuguese strains of colonial green microalga Botryococcus bruanii Kutz obtained from Coimbra Collection of Algae (ACOI), were evaluated on their potential for biofuel production, which was assessed from batch culture in photobioreactors under indoors and outdoors conditions using pretreated waste water and semisynthetic culture media. In the experiments, the maximum specific growth rate achieved was 0.4 day-1 with doubling times ranging from 2 to 7 days in the fastest growing phase. However, both strains showed ability to absorb nutrients in waste water cultures, to grow and accumulate oil. The maximum lipid extraction on a dry matter basis was 36% in CHU media and 29% in waste water cultures, which revealed the promising potential of these B. braunii isolates to be used in biofuel production applications. This is also supported by the predominance of oleic (C18:1, 42 to 63%) and palmitic acid (C16:0, 8 to 18%) in the lipid extract, since the methyl esters of these fatty acids (FAME) are ideal for biodiesel production. In summary, although these strains of B. braunii have presented a typical growth for this species, they produced considerable lipid content and were able to grow in waste water and under outdoors conditions that warrants further investment in their study.

The growing shortage of fossil fuels caused an increase in the demand for alternative and renewable fuels. Biofuels, like bioethanol and biodiesel, have received more attention as a sustainable replacement of fossil fuels. However, these have a poor oxidative stability, little energy content by volume, and many oxygenated compounds, which may cause corrosion and damage to the engines. Therefore, they are used as a mixture with standard fuels. Some species of microalgae are candidates to produce oils as triglycerides (TGA) to produce biodiesel by transesterification; however, the problem will remain. The colonial microalgae Botryococcus braunii produces and accumulates a high amount of long-chain nonoxygenated hydrocarbons, similar to those obtained from the fractionated distillation of crude petroleum. This is one of the few organisms reported to have a direct contribution in the formation of the oil reserves currently in use. Additionally, B. braunii produces pigments and long-chain carbohydrates that have interesting properties for various industries. There are still problems to be solved in order to consider it as economically viable and profitable, but important progress is being made. Therefore, this microalga is very attractive for the synthesis of hydrocarbons and other value-added compounds, making it an interesting biorefinery organism.

“…The lipid content of microalgae normally varies between 1 and 40% and, under certain conditions, it may be as high as 85% of the dry weight. In the case of B. braunii, one of the most scrutinized microalgal lipid producers, a total of 75% (w/w) of hydrocarbons in cell mass were reported [36,37]. A large number of monounsaturated, polyunsaturated and even branched hydrocarbons are produced by B. braunii.…”

“…A large number of monounsaturated, polyunsaturated and even branched hydrocarbons are produced by B. braunii. These compounds can be chemically converted into biodiesel by the well-established alkaline transesterification with alcohols such as methanol [36]. Glycerol phase is the main by-product of this transesterification process and can be commercialized in the food industry as humectant (E422) or can be applied for manufacturing cosmetic products [9].…”

Microalgae (including cyanobacteria) are promising organisms for sustainable products for use as feedstocks for food, feed, fine chemicals, and biofuels. They can synthesize a broad range of products with medium‐ to high‐value market price such as β‐1,3‐glucan polysaccharide, single‐cell‐protein, carotenoids and phycobilin pigments, and long‐chain polyunsaturated fatty acids that are commercialized in the food industry as dietary supplements and functional foods, in the pharmaceutical and chemical industries as cosmaceuticals and flavorants, and in the therapeutic field as nutraceutical compounds. These microorganisms are also exceptional producers of omega‐3 and omega‐6 fatty acids such as eicosapentaenoic, docosahexaenoic, and arachidonic acids that have been linked to several human health benefits. The aim of this paper is to review the main existing high‐value products that can be derived from microalgae with a particular focus on food science and technology applications. It also describes the gross and fine chemical composition of various algal species and details the nutritive importance of selected constituents. Finally, nutritional quality standards and legislative provisions to ensure food safety in the use of algal biomass are presented.
