Abstract

Modern trends in improving the design of membrane devices for photoautotrophic biosynthesis dependent lighting microorganisms aimed at a significant increase in the productivity of valuable products from biomass of microalgae and obtaining on the basis of their individual useful substances (drugs) used in various industries and medicine. In film devices effectively the processes of heat - and mass-exchange with the gas comes into contact with the culture fluid flowing as a film on a transparent film-forming surface is STI in its light intensity and autotrophic biosynthesis occurs only in the presence of a mixture of air with carbon dioxide. Thus, completely eliminated the accumulation of metabolic products due to their continuous removal from film culture liquid with the process gas, which is not typical for devices of other types. Small size membrane bioreactors may increase the degree of saturation of the liquid carbon dioxide with the possibility of changing the concentration of gas in the culture fluid and to ensure the cultivation of microorganisms with a specified biomass yield. At present up to date-developed a significant number of ways to ensure contact of the gas with the liquid (bubbling, gas-lift, mechanical stirring, jet, membrane, etc.) on the basis of which an industrial bioreactor, with various "stress" effect. It is believed that for the cultivation of the most optimal are bioreactors with mechanical stirring of the liquid, which allow the greatest productivity of biomass. However, the applied model of a mechanical mixing device to create a work whose cavity of the bioreactor chaotic, disorganized mixing, which contributes to the emergence, insufficient for the sustenance of the cell cultures and microorganisms. Analysis of the interactions of the gas with the liquid film devices showed the need to create a new generation of bioreactor with intensive mass transfer without the possibility of limiting the productivity of biotechnological systems. The work shows a consistent change in structural elements of membrane bioreactors to increase the efficiency of their operation.
