Large-Scale PBRs

PSI Large-Scale Photobioreactors are systems that create a controlled artificial environment for upscaling of photosynthetic microorganisms' biomass production. Standard systems are based on flat cultivation vessel (25 l or 100 l in volume) whereas customized systems comprising range of various cultivation tanks that meets different customers' requirements. The cultivation unit is operated by the stand-alone Control Unit. Read more

Optical density and Chlorophyll- a fluorescence determination

Variable cultivation strategies (pH-stat, turbidostatic, anaerobic, etc.)

Further upscaling by PBRs cascading

Compact design with wheels for easier manipulation

Large-Scale Photobioreactors PSI Large-Scale Photobioreactors are systems that create a controlled artificial environment for upscaling of photosynthetic microorganisms' production and their metabolites. Standard systems are based on flat cultivation vessel (25 l or 100 l in volume) whereas customized systems comprising range of various cultivation tanks that meets customers' requirements. The cultivation unit is operated by the stand-alone Control Unit.

Flat, rectangular glass cultivation vessel with a short light path (6.5 cm ± 5 %) for an optimal irradiance.

Different size: 25 l, 100 l.

Integrated temperature sensor, water level sensors, heater, foam trap.

Stainless steel vessel lid with gas and electronics fittings accompanied with silicone sealings.

Integrated aeration plastic U-tube with porous polyethylene sparger (pore size 50 µm). Autoclavable (with limited reuse).

Aluminum frame with wheels for easy manipulation.

Thermoregulation In-built temperature regulation in the range of 30 - 60 °C (with ambient temperature around 20 °C). Cooling module (optional) widens the temperature range to 15 - 60 °C (ambient temperature not exceeding 30 °C). It includes water cooling coil, cooling unit, electronics and software control.

Illumination LED technology. Bi-color light panel with separately controllable channels. Cool white-red. Other color combination on request. Total illumination intensity up to 500 and 300 µmol. m -2 . s -1 for white and red light, respectively. Optionally, up to 2,200 µmol. m -2 . s -1 with the Light Upgrade (available only for 25 l PBR). Light path: 6.5 cm ± 5 %. Illumination is independently adjustable for light color in intensity, timing and modulation. Constant light conditions or the alternation of various light and dark cycles. The duration of the individual cycles: from seconds up to days. The mode of the light cycles: constant, linear increase or decrease, sinusoid mode for simple imitation of diurnal rhythms. Moreover, java scripting is incorporated in the Photobioreactor Control Software (advanced version) for a creation of the advanced light protocols (for example automatic light intensity adjustment in dependence on the actual biomass concentration). Additional Protective Glasses: Radiation safety glasses protecting against excessive LED radiation - equipped with side cover and protective filters. One pair of glasses is provided with the device free of charge.
