Fed-batch addition of urea for Spirulina platensis cultivation : Thermodynamics and material and energy balances

Previous results of Spirulina platensis cultures, carried out by supplying intermittently urea as nitrogen source at exponentially increasing feeding rate, have been used to perform a bioenergetic and thermodynamic study on the growth of this cyanobacterium as well as on its photosynthetic efficienc...

Beschreibung
Zusammenfassung:	Previous results of Spirulina platensis cultures, carried out by supplying intermittently urea as nitrogen source at exponentially increasing feeding rate, have been used to perform a bioenergetic and thermodynamic study on the growth of this cyanobacterium as well as on its photosynthetic efficiency. Simple material, enthalpy and Gibbs energy balances have been applied to the results obtained alternately varying either the total time of nitrogen source feeding (9< t T
