3 DEVICE DESCRIPTION
Standard version of the Photobioreactor FMT150 consists of a cultivation vessel with a sealable lid and a base box
containing electronics circuitry, LED light panel (Fig. 1A) and other components essential for the optimal operation of the
photobioreactor.
Fig. 1 A) Photobioreactor body consists of a flat vessel holding the suspension and of a base box with electronic circuitry. B) The block
scheme of the instrument shows the Control Processor Unit exchanging data and protocol with external computer (PC) and auxiliary
external modules. The Control Unit governs measurements of parameters such as OD and chlorophyll fluorescence plus parameters
measured by auxiliary sensors. It also controls the actinic light sources and temperature of the culture. C) Detail of the LED
configuration. D) Uncorrected optical density spectrum of cyanobacterial suspension. The lines with arrows indicate wavelengths of
various light sources that are integrated in the instrument. The detection range of the photodiode is also shown. E) Detail (rotated
top-to-bottom view) of the fluorometer and densitometer. F) Schematic representation of optional gas supply components and
modules that can be used to stabilize aeration and set CO
2
concentration level.
