“…[75] It was demonstrated that decreasing light supply from 20 to 10 sm increased biomass accumulation by three times and nitrogen and phosphorus recovery rates by almost 2.5 times.

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

An experimental study of the formation of the structure of a closed vortex motion of a liquid in a vertical cylindrical container with a rotating end (disk) under various boundary conditions has been carried out. The regimes of formation of the circulating motion of a liquid with a small aspect ratio are experimentally investigated. The studies have been carried out using the Particle Image Velocimetry method in a horizontal cross-section near the interface in a cylinder and near the bottom in a gas-vortex reactor. It has been found that with a small aspect ratio in an open cylinder near the air-liquid interface, a region is formed near the axis, in which the radial velocity component is close to zero. Consequently, the circulation is not formed in the entire volume, and the efficiency of mass transfer decreases. At the same time, at a solid boundary, as well as at the liquid-liquid interface, a circulation flow of the working fluid is formed even at a small aspect ratio.
