The present work investigated the effects of nitrogen (N), phosphorus (P), magnesium (Mg), carbonate (CO 3) concentrations and gamma radiation doses on growth and lipid production of Chlorella vulgaris. The obtained results showed that culture conditions have highly significant effects on biomass and lipid accumulation. The maximum lipid content was observed at 350, 40, 150,20 mg L −1 of N, P, Mg, and CO 3 concentrations, respectively. While the highest biomass yield was achieved at high N and P as well as reduced Mg and CO 3 concentrations. Whereas gamma radiation showed a negative effect. Lipid profile recorded maximum saturated (SFAs, 62.44%) and unsaturated fatty acids (UFAs, 37.56%) with palmitic acid (C16:0), linoleic acid (C18:2), pentadecanoic acid (C15:0), palmitoleic acid (C16:1) and oleic acid (C18:1) as predominant fatty acids, which prove that Chlorella vulgaris is a promising feedstock for biodiesel production.

The effect of ammonia and iron concentration in Bold Basal Medium and mixed wastewater (including pretreated piggery wastewater and acid mine drainage) on biomass production and biochemical content (lipid and ß-carotene) of microalgae (Uronema sp. KGE 3) was investigated. Addition of iron to the Bold Basal Medium enhanced the growth, lipid, and ß-carotene of Uronema sp. KGE 3. The highest dry cell weight, lipid content, and lipid productivity of KGE 3 were 0.551 g L-1, 46% and 0.249 g L-1 d-1, respectively, at 15 mg L-1 of Fe. The highest ß-carotene was obtained at 30 mg L-1 of Fe. The biomass production of KGE 3 was ranged between 0.18 to 0.37 g L-1. The microalgal growth was significantly improved by addition of acid mine drainage to pretreated piggery wastewater by membrane. The highest dry cell weight of 0.51 g L-1 was obtained at 1:9 of pretreated piggery wastewater by membrane and acid mine drainage for KGE 3. The removal efficiencies of total nitrogen and total phosphate was ranged from 20 to 100%. The highest lipid and ß-carotene content was found to be 1:9. Application of this system to wastewater treatment plant could provide cost effective technology for the microalgae-based industries and biofuel production field, and also provide the recycling way for pretreated piggery wastewater and acid mine drainage.

Summary This paper reviews some of the most important aspects of microalgae as a potential source for biodiesel production. Microalgae are photosynthetic microorganisms that can grow rapidly in a variety of environments because of their unicellular or multicellular structure depending on the species. They have the advantage of self‐reproduction using solar energy and converting it into chemical energy via photosynthesis. This process concludes a full cycle in a few days, obtaining higher lipid yields than terrestrial crops. This review shows several techniques and some methodologies used in the biodiesel production process from microalgae as well as the challenges that must be overcome for large‐scale process and in bio‐refineries.
