All system fermentation that i found to microalgae cultive are made in a fermenter machine. I would like to know if it is possible cultive heterotrophic microalgae in an INOX PBRs syste.
Photobioreactors PBRs are exposed to light, they are used for autotrophic and mixotrophic microalgae growth. Heterotrophic microalgae can grow in presence of light but also in darkness if have proper nutrients. It is possible to grow heterotrophic microalgae in PBRs but only in those types which allow organic substrate feeding and substrate mixing needs. Darkness is not a problem for such microalgae (I suppose INOX means stainless steel) but limitation of vertical bioreactors comes from impossibility to deal with viscosity characteristic and with a proper distribution of organic nutrients.
