“…TAGs are found ubiquitously as major carbon storage molecules in plants, animals, algae and microorganisms [10,11]. Although algae have been explored as a renewable source for lipid-based fuels owing to the ability to produce substantial amounts of TAGs, it is considered that commercial-scale production of biofuels from algae is incompatible with existing technologies [12,13]. Oleaginous microbes that utilize a wider variety of substrates provide opportunities for TAG production from lignocellulosic biomass [14].…”

Triacylglycerols (TAGs) are in the spotlight as a feasible source of hydrocarbon-based biofuels. Rhodococcus opacus PD630 produces large amounts of intracellular TAGs in cultivations containing high concentrations of glucose, but it does not utilize xylose present in all hydrolysates of lignocellulosic biomass. We constructed a highpotency xylose-fermenting R. opacus strain MITXM-61 that exhibited robust growth and TAG biosynthesis on high concentrations of xylose by activating potential xylose-metabolism genes. MITXM-61 had the uncommon capacity to grow in defined media supplemented with xylose at concentrations of greater than 200 gl -1 . MITXM-61 grown in corn stover hydrolysates containing 118 gl -1 of initial total sugars was capable of completely and simultaneously utilizing both xylose and glucose in the genuine lignocellulosic feedstock, and yielded 15.9 gl -1 of TAGs, corresponding to 54% of the cell dry weight. The oleaginous bacterium R. opacus strain proved useful for developing a new manufacturing paradigm to generate advanced lignocellulosic biofuels.

“…Notwithstanding these many advantages, the relatively high cost of algal biofuels (US $300-2600 per barrel) compared to petroleum (US $40-80 per barrel) indicates further improvements in technology are required to make it costcompetitive and commercially scalable (Hannon et al, 2010;Pienkos and Darzins, 2009;Singh et al, 2011;Wijffels and Barbosa, 2010). One of the potential solutions to the above problem is to enhance the lipid production capabilities of microalgae by inducing nutrition-deficient conditions in order to channel metabolic fluxes towards lipid biosynthesis.…”

Microalgal biofuels offer great promise in contributing to the growing global demand for alternative sources of renewable energy. However, to make algae-based fuels cost competitive with petroleum, lipid production capabilities of microalgae need to improve substantially. Recent progress in algal genomics, in conjunction with other ''omic'' approaches, has accelerated the ability to identify metabolic pathways and genes that are potential targets in the development of genetically engineered microalgal strains with optimum lipid content. In this review, we summarize the current bioeconomic status of global biofuel feedstocks with particular reference to the role of ''omics'' in optimizing sustainable biofuel production. We also provide an overview of the various databases and bioinformatics resources available to gain a more complete understanding of lipid metabolism across algal species, along with the recent contributions of ''omic'' approaches in the metabolic pathway studies for microalgal biofuel production.

“…Fatty acid content of algae lipid. [23], [31] The utilization of traditional biomass waste is an evidence that Nigeria already has a good use of biofuels as an alternative source of energy as it takes up the largest percentage of the primary energy consumption of the Nigerian populace reveals. This is revealed in the edge this utilization has over other forms, particularly with oil which is a major export commodity of Nigeria taking just meagre 11 % of the primary.…”

-The issue of energy consumption is one of the issues that have significantly become recognized as an important topic of global discourse. Fossil fuels production reportedly experiencing a gradual depletion in the oil-producing nations of the world. Most studies have relatively focused on biofuel development and adoption, however, the awareness of a prospect in the commercial cultivation of algae having potential to create economic boost in Nigeria, inspired this research. This study aims at exploring the potential of the commercialization of a different but commonly found organism, algae, in Nigeria. Here, parameters such as; water quality, light, carbon, average temperature required for the growth of algae, and additional beneficial nutrients found in algae were analysed. A comparative cum qualitative review of analysis was used as the study made use of empirical findings on the work as well as the author's deductions. The research explored the cultivation of algae with the two major seasonal differences (i.e. rainy and dry) in Nigeria as a backdrop. The results indicated that there was no significant difference in the contribution of algae and other sources of biofuels as a necessity for bioenergy in Nigeria. However, for an effective sustainability of this prospect, adequate measures need to be put in place in form of funding, provision of an economically-enabling environment for the cultivation process as well as proper healthcare service in the face of possible health hazard from technological processes. Further studies can seek to expand on the potential of cultivating algae in the Harmattan season.
