“…In this study, after 30 days there has been no sign to the phase of death, so the possibility of this growth will still occur with cultivation more than 30 days. Research conducted by Al-Hothaly et al (2015) showed that Botryococcus sp. had the log growth phase until 40 days.…”

Botryococcus sp. is an economically important microalgae as it contains carbohydrates, lipids, proteins, and a number of phytochemicals. The high concentrations of saturated fatty acids (SFAs) and monounsaturated fatty acids (MUFAs) in this strain also a valuable source for production of biofuel. Mutagenic engineering using irradiation has been known to increase the content of these biomass. The aim of this study is to know the effect of electron-beam irradiation to the growth profile and fatty acid composition of Botryococcus sp. In this study, Botryococcus sp. adjusted an optical density 1.0 after being exposed to different doses of electron-beam irradiation (160 kGy, 240 kGy, and 320 kGy) and induced random mutagenesis for strain improvement was observed based on high energy (1.5 MeV and 2 mA). Several mutants obtained were designated as strain B160, B240, and B320, respectively. The profile growth was significantly different between control (0 kGy) and irradiated microalgae strain. The highest growth is found in B320 mutant. Fatty acid of Botryococcus sp. control produced 7 fatty acids, B160 produced 7 fatty acids, B240 produced 6 fatty acids, whereas B320 produced 9 fatty acids. B320 produced hydrocarbon and phtalic acid as well as fatty acids. Total SFAs and MUFAs of B240 was increased 1.6 times compared to the wild type. The results would give some implications to improve the quality of biodiesel from Botryococcus sp.

“…Del proceso de análisis por GC-MS se obtuvieron picos a tiempos de retención de 28.05 minutos que corresponden a un 91% del área total de la muestra, utilizando hexano como solvente y de acuerdo a la comparación con las muestras patrón (alcanos), la biomasa obtenida corresponde a carbonos en el intervalo C26 -C32. De acuerdo a la bibliografía esto corrobora a la variedad de Botryococcus braunii del tipo A que se caracteriza por formar n-alcadieno y / o N-trienos (C23 -C33) [20] pero por el número mayor de carbonos detectados que fueron 32 se puede prever que también generó botriococenos (C30 -C37) y escualenos metilados (C31 -C34) [21], [22] Tal como se observa Botryococcus braunii puede acumular niveles inusualmente altos de hidrocarburos triterpenoides, lo que lo convierte en una fuente potencial de productos químicos de alto valor [23].…”

The idea of using microalgae as a biosource of biodiesel is being taken seriously because of the escalating price of fossil fuel. The objective the research was to determine the optimal levels of concentrations of sulfate, carbonate, nitrate and phosphate in the performance of biomass, by assessing the individual and combined effect of concentrations on the growing of the microalgae, through the application of a type-24 factorial experimental design in the performance of Botryococcus braunii biomass isolated in the high-Andean zone of Cajamarca-Perú. According to the results of the study of individual effects of these four salts, it was stated that carbonate and nitrate salts have significant effect on the growing of Botryococcus braunii (p<0.05). This was characterized by using a chromatography equipment of gases adapted to mass and it was found that hydrocarbons generated have 26 to 32 carbons in their composition.

“…In a different study by Szydłowska‐Czerniak et al, significant loss of phenolics and a considerable decrease of antioxidant capacity occurred in the bleaching step of the palm oils. Tocopherols, carotenoids, and other bioactive substances are also present in microalgal oils . Therefore, physical refining requires temperature and vacuum optimization during steam distillation, and chemical refining must further reduce the effect of alkali conditions on the retention of bioactive constituents in microalgal oils.…”

Microalgae are considered an interesting candidate for the sustainable production of edible oils. Because microalgae contain abundant polyunsaturated fatty acids (PUFA) and have high photosynthetic rates and high oil productivity, they are superior to terrestrial oleaginous crops for producing edible oils. Microalgae are cultivated in aquatic environments, and thus, oil extraction methods for microalgae must consider the influence of water. This paper provides an overview of the suitability of microalgal lipid compositions and proposes a selection of species for edible oil production. The numerous technologies currently available for pretreatment, wet extraction and the refining of edible oils from microalgae are collated and presented, with a primary focus on the key parameters influencing process performance. Furthermore, the paper presents a proposed solution for a microalgae integrated system for edible oil production, which is a possible future direction to develop an economical and environmentally friendly process for the resource utilization of microalgal biomass. Practical Application: Microalgae might be the most promising source of edible oils, with potential applications in food industrialization, due to its rich oil content and its characteristic fatty acid composition. The review provides a selection criterion of microalgal species to help researchers exploit microalgae to produce superior edible oils for human consumption. Various process parameters and wet extraction methods are discussed that may be conducive to improving process performance and achieving high oil recovery yields. By considering the maximum utilization of microalgal biomass, an integrated system in this review would assist in economical production during further studies. Microalgae are the most promising candidates for edible oil production. Cell disruption, extraction, and refining are important processes for microalgal oils and on this basis, wet extraction and resource utilization can further promote the economic feasibility of microalgal process.
