BOFFILL-RODRIGUEZ, Yanet; GARCIA-RODRIGUEZ, Agustín  y  CASTELLANOS-ESTUPINAN, Jesús. Preliminary quantitative estimate production rates of microalgal biomass from the reaction of photosynthesis. RTQ [online]. 2012, vol.32, n.1, pp. 31-41. ISSN 2224-6185.

A preliminary quantitative estimation of biomass microalgae index production it is presented in this paper, for which the stoichiometric coefficients of photosynthesis reaction were calculated under different considerations. Nine alternative of equations were evaluated, where the CO₂ is used as sole carbon source; the ammoniac (NH₃) and the ammonia nitrate (NH₄NO₃) as nitrogen sources, and the ammonia phosphate ((NH₄)₃PO₄)), the phosphate monoammonic ((NH₄) H₂PO₄)) and phosphate diammonic ((NH₄)₂HPO₄) were used as nitrogen and phosphor sources. Five alternatives fixed the mass balances to obtain the values of the stoichiometric coefficients corresponding to the proposed algae formula. The maximum yield of cell is calculated as Y(B/s), resulting in a value of 0,82 g microalgae/g CO₂, equivalent to 1mol microalgae/mol CO₂.

Palabras clave : photosynthesis; carbon dioxide; microalgae biomass; mass balance; stoichiometric coefficients.
