The microbial lipids, alike to plant oils, comprise palmitic, stearic, oleic, and
linoleic acid with unsaturated fatty acids adding up to 64% of the whole fat acid
substance (Singh and Nigam 2014).
Microbial oils, as single cell oils for the production of biofuels produced by
microorganisms, are believed to be a promising potential feedstock (Zhu et al. 2008).
The oil value of algae concerning their dry weight made them the perfect sustainable
fuel (Table 1.2) (Adeniyi et al. 2018; Kirrolia et al. 2013).
The oil value of microalgae is generally among 20–50%, whereas certain strains
can attain as great as 80% (Table 1.3) (Singh and Nigam 2014; Wen and Johnson
2009; Adeniyi et al. 2018).
Algae oil can be manufactured at speeds of up to 500 times the speed per acre of
any other source of plant oil (Taparia et al. 2016). As to similarity of these
microorganisms with culture various conditions autonomy from the periods of the
year, the fast development rate, engrossing carbon dioxide and improving air quality,
sustainability, non-contending with food supplies, microalgae are known as one of
the most appropriate alternatives for the biofuel creation (Boshagh et al. 2019).
Contingent upon kinds and cultivation technique, microalgae may deliver
biohydrogen, biomethanol, and bioethanol. A few types of green algae, for example,
Botryococcus braunii and Chlorella protothecoides, enclose elevated ranks of
terpenoid hydrocarbons and glyceryl lipids. These algae have excessive possibility
for the creation of oil fuels likely bioethanol, triterpenic hydrocarbons, and
