Growth of microalgae

There are two main ways in the biological utilisation process greenhouses carbonic fertilisation and growth of microalgae.

Since dissolved inorganic carbon, such as free CO2 and bicarbonate, acts as a sole carbon source in photoautotrophic growth of microalgae, the partial pressure of CO2 in the atmosphere or in the supplied gas mixture is an important factor for their growth. Studies on the mechanisms underlying the efficient photosynthesis of microalgae in air level CO concentration (L-COj, 0.036%) will be described. 

Some studies attempted further characterization of the arsenic compounds in algae [137], which involved the growth of microalgae, Tetraselmis chuii [138], Chaetoceros concavicornis [139] in media containing radiolabeled arsenate. 

Figure 1 Schematic presentation of photoautotrophic growth of microalgae. The dark green (gray in the print version) organelle represents the chloroplast where photosynthesis takes place. The blue (dark gray In the print version) organelle represents the mitochondria where the respiratory machinery is located. The compound CH2O represents sugar.
