Thirty microalgal strains were screened in the laboratory for their biomass productivity and lipid content. Four strains (two marine and two freshwater), selected because robust, highly productive and with a relatively high lipid content, were cultivated under nitrogen deprivation in 0.6‐L bubbled tubes. Only the two marine microalgae accumulated lipid under such conditions. One of them, the eustigmatophyte Nannochloropsis sp. F&M‐M24, which attained 60% lipid content after nitrogen starvation… 
Strategies to Improve Oil/Lipid Production of Microalgae in Outdoor Cultivation Using Vertical Tubular-type Photobioreactors
TLDR
The results show that the proposed two-stage process was able to avoid the bacterial contamination and enhanced the lipid content and lipid productivity of Chlorella vulgaris ESP-31.
Nitrogen starvation strategies and photobioreactor design for enhancing lipid content and lipid production of a newly isolated microalga Chlorella vulgaris ESP‐31: Implications for biofuels
TLDR
Comparison of single‐stage and two‐stage nitrogen starvation strategies shows that single-stage cultivation on basal medium with low initial nitrogen source concentration was the most effective approach to enhance microalgal lipid production, attaining a lipid productivity of 78 mg/L/d and a lipid content of 55.9%.

TLDR
The study leads to the conclusion that the two-phase culturing system with nitrogen starvation as post-harvest treatment would be suitable for gaining maximum biomass productivity, and lipid content of high quality fatty acids.
Chlorella for protein and biofuels: from strain selection to outdoor cultivation in a Green Wall Panel photobioreactor
TLDR
The environmental and economic sustainability of Chlorella production was enhanced by growing the organisms in a seawater-based medium, so as not to compete with crops for freshwater, and at high temperatures,So as to reduce energy consumption for cooling.

Increased lipid production of the marine oleaginous microalgae Isochrysis zhangjiangensis (Chrysophyta) by nitrogen supplement.
TLDR
Results revealed that this algal strain can accumulate lipids under nitrogen-repletion conditions and accumulate carbohydrate under nitrate-depletion conditions, which makes I. zhangjiangensis an ideal candidate for producing biodiesel using N-rich wastewater.
