Optimized Photosynthesis by High-Precision Lighting

25.09.2009
New PhotoBioreactor Illuminates Variety of Phototropic Cells with Selective Light Spectra

Phototrophic organisms ranging from green and red algae, to cyanobacteria, green sulfur bacteria and plant suspensions, can now enjoy optimal lighting conditions in bioreactors.


Making this possible are LED illuminators from DASGIP, which are integrated in the bioreactor. Creating specific light emissions at 457 nm, 660 nm, 560 nm and 623 nm gives a wide range of phototropic cells exactly the light spectrum they need for optimal production.

By arranging several LEDs in up to four illuminators inside the bioreactor, optimum light conditions for growth and photosynthesis are provided. The spectral composition as well as the light intensity can be predefined and adjusted online with the DASGIP Control Software 4.0.

Users who work with phototropic cells can take advantage of the advanced process control features offered by DASGIP systems: monitoring and control of temperature, pH, dissolved oxygen and redox potential, agitation, gassing with pure and mixed gasses, sampling, fully integrated exhaust gas analysis, monitoring of the optical density and the precise feeding of up to eight different liquids.

The PhotoBioreactor is based on an enhancement of the DASGIP benchtop line of reactors designed for microbiology and cell cultivation applications. They can be transformed into PhotoBioreactors - and back into usual benchtop reactors - in just a few easy steps. That means the PhotoBioreactors fit perfectly in the modular design of the DASGIP systems, which stand out due to their highly-efficient application potential in biotechnology laboratories. In truly parallel operation with up to 16 reactors, the DASGIP system yields reproducible, reliable and easily scalable process results.

About DASGIP: DASGIP AG develops and manufactures technologically advanced Parallel Bioreactor Systems for the cultivation of microbial, plant, animal and human cells at bench top scale. Process engineers, scientists and product developers from biotechnological, pharmaceutical and chemical companies as well as research institutions use DASGIP Parallel Bioreactor Systems for their biotechnological processes and benefit from increased productivity, high reproducibility, and ease of scale up, resulting in accelerated product development cycles. DASGIP is located in Juelich (Germany) and Shrewsbury MA (USA)

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

Im Focus: Entangled atoms shine in unison

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
