Biofuel production by a sustainable method using microalgae is entirely dependent on biomass production. However, commercialization at large scale using microalgae is a major obstacle using analytical grade growth nutrients, due to their cost effectiveness. Hence, development of a cost effective method is essential to reduce the production cost. Therefore, the present study envisaged the effect of low-cost commercial fertilizers such as urea, sodium bicarbonate, magnesium sulfate, potash and di-ammonium phosphate as growth nutrients for the production of biomass and total lipid of Botryococcus braunii were made. The biomass and total lipid production were optimized using

Lipid production is an important indicator for assessing microalgal species for biodiesel production. In this work, the effects of medium composition on lipid production by Scenedesmus sp. were investigated using the response surface methodology. The results of a Plackett–Burman design experiment revealed that NaHCO3, NaH2PO4·2H2O and NaNO3 were three factors significantly influencing lipid production, which were further optimized by a Box–Behnken design. The optimal medium was found to contain 3.07 g L−1 NaHCO3, 15.49 mg L−1 NaH2PO4·2H2O and 803.21 mg L−1 NaNO3. Using the optimal conditions previously determined, the lipid production (304.02 mg·L−1) increased 54.64% more than that using the initial medium, which agreed well with the predicted value 309.50 mg L−1. Additionally, lipid analysis found that palmitic acid (C16:0) and oleic acid (C18:1) dominantly constituted the algal fatty acids (about 60% of the total fatty acids) and a much higher content of neutral lipid accounted for 82.32% of total lipids, which strongly proved that Scenedesmus sp. is a very promising feedstock for biodiesel production.

“…So far, various studies have been carried out to demonstrate that the nitrogen source was the important nutrition in the medium affecting the growth and lipid accumulation (Li et al 2008). There was evidence to suggest that nitrogen deficiency could stimulate lipid accumulation (Mandal and Mallick 2009;Welter et al 2013).…”

The current study utilized Box-Behnken design of the response surface methodology, aimed at identifying the best levels of particular variables. An experimental design was performed on Chlorella sp. considering initial nitrogen, phosphorus and iron concentration as independent variables. Lipid, biomass, chlorophyll, carbohydrate and protein contents were analysed as response variables. Various physio-biochemical attributes were studied under varied concentration of nutrients in BG11 media, nitrate (NaNO 3 , 10-750 mg mL −1), phosphate (K 2 HPO 4 , 40-120 mg mL −1), iron (ferric ammonium citrate, 3-9 mg mL −1) with an objective to establish the actual potential of Chlorella pyrenoidosa under phototrophic nutrient stress conditions were obtained lipid percentage (35.4 dcw%) and biomass yield (1.89 g L −1). A Prob > F value of < 0.05 and > 0.05 indicated model terms which were significant and non-significant, respectively. The fit of model yielded R 2 values up to 96.25% for lipids and 94.12% for biomass; similar values were obtained for proteins, carbohydrate and chlorophyll. FAME profile of Chlorella pyrenoidosa contained palmitic (C16:0, stearic acid), (C18:0) oleic (C18:1), linoleic C18:2 and linolenic (C18:3) which showed that Chlorella pyrenoidosa possessed a favourable fatty acids profile that can be successfully utilized for biodiesel production.
