LIGHTEX® TECHNOLOGY
AN INNOVATIVE PHOTOBIOREACTOR MADE OF A
MULTILAYER OF LIGHTEX® / LUMINOUS FIBER OPTIC FABRIC
Based on a Lightex® bright double-sided panel, a plane photobioreactor with internal volumetric illumination–PRIAM, has been developed in cooperation with University of Nantes (France).
Lightex® panel between
2 polymer plates
Multilayer stack of Lightex plates illuminating culture chambers
Innovative PRIAM PhotoBioReactor
Patented PBR technology (2015)
PRIAM PROTOTYPE
A BREAKTHROUGH PHOTOBIOREACTOR WITH INTERNAL
VOLUMETRIC ILLUMINATION FOR A VERY HIGH PRODUCTIVITY OF MICROALGAE
PRIAM PROTOTYPE
- Floor area 1 m²
- Height 2 m
- Specific light area ~500 m2 m3
- Liquid volume ~10 liters (5 panels)
- In situ control of pH, temperature, …
PRE-INDUSTRIAL SYSTEM
Continuous productivity
3.75 kg m-3 day -1
NO BIOFILM !!
- closed system in a sterile environment
- cGMP production of microalgae
- modular design
To our knowledge : no equivalent system
CASE STUDY
PRODUCTION AND REFINING OF PORPHYRIDIUM CRUENTUM
Porphyridium cruentum is a challenging case, because of the production
of exopolysaccharides, a sticky material creating biofilm troubles
Production
validated in PRIAM prototype
NO BIOFILM !!
phycoerythrin (B-PE) ~4% immunofluorescent tracer 
exopolysaccharides (EPS) 30-40% antiviral components
zeaxanthine ~1% antioxydants

AlgoLight enables the INDUSTRIAL production of
- Pharmaco-active metabolites (anti-viral, anti-cancer, anti-bacteria, anti-inflammatory, neuro-protectant, …)
- Biopharmaceuticals, recombinant proteins in transgenic microalgae
- Toxic metabolites (bioactives, veterinary products, pest control,…)
- Life support for human space exploration
