Controlled and Intensified production of microalgae

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).

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

other

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
