2 GENERAL DESCRIPTION
Photobioreactor FMT150 feature a unique combination of the cultivator and computer controlled monitoring device. The
Photobioreactor FMT150 combines a cultivation vessel with the built-in fluorometer and densitometer. It is primarily
designed for modular and precise phototrophic cultivation of algae, cyanobacteria and bacteria. Light power and spectral
composition as well as temperature and aeration gas composition can be set with high accuracy.
User defined cultivation conditions can be dynamically varied according to user defined protocol. Continuous online
monitoring of cultivation conditions and measured parameters is possible via the optional PBR software. Light,
temperature, gas composition, and culture medium regime can be programmed to oscillate with various amplitudes and
frequencies with user-defined time steps from seconds to hours via the software or via the control unit. Turbidostatic
cultivation can be used for the stabilization of the suspensions via optical density control. In addition, up to 8 peristaltic
pumps for different chemostat cultivation control can be linked to the Photobioreactor FMT150 for the highly precise
control of cultivation conditions.
The growth of the cultures is monitored by the integrated densitometer (OD 720, 680 nm). Relative chlorophyll content of
the culture can also be monitored continuously by the difference of optical densities at 680 and 720 nm. The instantaneous
physiological state of the culture is measured by the Photosystem II quantum yield Fv/Fm.
The Photobioreactor FMT150 has a flat-vessel design that enables uniform illumination over the whole culture.
Photobioreactors are currently manufactured in three cultivation vessel capacities: 400 ml, 1000 ml and 3000 ml.
All Photobioreactor models may be supplied with a number of optional accessories – sensors, stirrers, pumps, etc. Control
of the Photobioreactor is possible with either the control unit of the photobioreactor itself or the PBR software. However,
the PBR software provides much wider functionality to define, control, display and analyze the experimental conditions
and data.
