“…nutrient deprivation), oleaginous microalgae can be induced to accumulate neutral lipids or triacylglycerides (Hu et al, 2008), which, among other applications, can be converted into biodiesel via transesterification. Microalgae can produce significantly more lipids than oil palms (Ahmad et al, 2011), and without competing for precious arable land, biodiverse landscapes (e.g. rainforests) or freshwater resources.…”

., RNA-Seq and metabolic flux analysis of Tetraselmis sp. M8 during nitrogen starvation reveals a two-stage lipid accumulation mechanism, Bioresource Technology (2017), doi: http://dx.doi.org/10. 1016/j.biortech.2017.06.003 This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form.

AbstractTo map out key lipid-related pathways that lead to rapid triacylglyceride accumulation in oleaginous microalgae, RNA-Seq was performed with Tetraselmis sp. M8 at 24 h after exhaustion of exogenous nitrogen to reveal molecular changes during early stationary phase. Further gene expression profiling by quantitative real-time PCR at 16-72 h revealed a distinct shift in expression of the fatty acid/triacylglyceride biosynthesis and β-oxidation pathways, when cells transitioned from log-phase into early-stationary and stationary phase. Metabolic reconstruction modeling combined with real-time PCR and RNA-Seq gene expression data indicates that the increased lipid accumulation is a result of a decrease in lipid catabolism during the early-stationary phase combined with increased metabolic fluxes in lipid biosynthesis during the stationary phase. During these two stages, Tetraselmis shifts from reduced lipid consumption to active lipid production. This process appears to be independent from DGAT expression, a key gene for lipid accumulation in microalgae.

“…Biodiesel is commonly produced by transesterification of triglycerides from vegetable oils with methanol obtaining fatty acid methyl esters (FAMEs) (Vicente, 2009). However, high manufacturing cost and the majority of raw materials such as vegetables oils which struggle with the food industry and need a very large percentage of the current available land are some disadvantages for biodiesel production (Ahmad et al, 2011). Oil from photosynthetic microorganisms such as microalgae has emerged as one of the most capable substitute sources of lipids to be used in biodiesel production because of its fast growth rates, cost effective photosynthesis and less competition for agricultural land when compared to conventional vegetable oil crops (Subbramaniam et al, 2010).…”

“…Feedstock is also a major contributor towards the overall cost of biodiesel production. Ahmed et al [12] reported that the feedstock contribution in the total cost of biodiesel production is 75 %. Demirbas [13] estimated that feedstock might contribute up to 80 % of the overall cost of biodiesel production.…”

“…Feedstocks for biodiesel must be available in plenty and at low price [14]. Biodiesel production should also be from those feedstocks which must minimize the greenhouse gases and must not compete with other useful food crops [12]. Karmakar et al [15] reported that due to the less availability of non-edible oils and their alternatives, there must be some diversification of feedstocks for the biodiesel production.…”

Pond-grown microalgae have been considered as feedstocks for production of biodiesel. Various natural habitats and man-made environments can be exploited to cultivate microalgae without utilizing arable land which is already decreasing due to urbanization and industrial development. Suitable temperature, solar illumination and availability of phosphorus and nitrogen-rich organic wastes result in algal blooms in stagnant water and river bank's associated pools in many regions including Pakistan.
