Abstract Microalgae are considered to be a promising group of organisms for fuel production, waste processing, pharmaceutical applications, and as source food components. Unicellular algae worth being because their capacity produce comparatively large amounts lipids, proteins, vitamins while requiring little room growth. They can also grow on fix CO2 nitrogen compounds. However, production costs limit the industrial use microalgae most profitable applications including micronutrient fish farming. Therefore, novel based technologies require an increase efficiencies or values. Here we review recent studies focused getting strains with characteristics cultivating techniques that improve production's robustness efficiency categorize these findings according fundamental factors determine Improvements light nutrient delivery, well other aspects photobioreactor design, have shown highest average in productivity. Other methods, such improvement phosphorus fixation temperature adaptation been found less effective. Furthermore, interactions particular bacteria may promote growth microalgae, although bacterial grazer contaminations must managed avoid culture failure.
