Photobioreactor

Photobioreactor PBR is a glass autoclavable photobioreactor with working volume 2-4.5 l (total volume 6.2 l, internal diameter - 150 mm). The bioreactor is used for precise phototrophic cultivation of algae and cyanobacteria.

Automation System

  • Stainless steel monoblock construction. In monoblock are included: bioprocess controller BIO-4, thermostat, peristaltic pumps, power parts, LED control, gas supply (air, CO2) and mixing unit.

Bioprocess controller BIO-4:

  • Colored 5.6" touch screen display,
  • Controls of pH, pO2, temperature, foam, level,
  • Remote control of the experiment via internet (SCADA Control System)
  • Data collection in real time.
  • Data visualization in graphs.
  • Display of all process data, (t, ph, pO2, etc.)
  • CO2 addition via pH control or manual gas control
  • LED-illumination;
  • Control of the illumination intensity as a time dependent profile program;
  • Day/night cycles;
  • Intensity control - 0 to 100% PWM (0 to 1500 µmol/m2/s);
  • The thermoregulation is carried out by circulation of thermostated water through a jacket in the photobioreactor bottom
  • Both static and Day-night temperature control
  • Mixing system for mycelial or other shear sensitive microorganisms consisting of 2 mixers with 3 pitched-blades.
  • Peristaltic pump for Chemostat mode cultivation, i.e. programed addition of substrate and other substances.
