Abstract: A method, process, apparatus, use and formulation for dual biocatalytic conversion of CO2 containing gas into carbon containing bio-products by enzymatic hydration of CO2 into bicarbonate ions in the presence of carbonic anhydrase and metabolic conversion of the bicarbonate ions into carbon containing bio-products in a biological culture. The dual biocatalytic conversion may be relatively constant with controlling a feeding of the bicarbonate ions to the biological culture in accordance with demands of the biological culture by retaining over-production of bicarbonate ions and feeding part of the over-production to the biological culture in accordance with nutrient demands of the biological culture. Bicarbonate ions may also be reconverted to generate a pure CO2 gas stream. The CO2 containing gas may be derived from operations of a power plant which receives a carbon-containing fuel for combustion, and the biological culture may be an algae culture.
