Why mineral carriers are needed for microalgae

Abiotic, biotic and anthropogenic factors inhibit normal life of microorganisms. We have showed that the mineral carrier provides
integrity and increases the growth of microalgal cells under stress conditions. Microalgae Chlorella vulgaris, immobilized on an analcime-containing rocks (biogeosorbent), are resistant to increased salinity (34 ‰) and organic pollutants (phenolic water with a concentration of 10 μg/dm3). The advantage of the synergetic complex of the biogeosorbent from its individual components is the reduction of the period of water purification from phenols. Biodestruction of 83 % of phenols in model water occurs in 3 days.
