The subject of the procurement is a complete lighting set for the phototrophic cultivation of cyanobacteria, specially adapted to our research questions. Cyanobacteria carry out photosynthesis and therefore require a light source. The light spectrum and the homogeneity of the illumination of the cultures have a decisive influence on growth rates, metabolic activity and cell stress. Therefore, expert planning and the use of adapted lighting concepts and light spectra are absolutely necessary. List of services: - Light sources for the cultivation of cyanobacteria in a cultivation shelf measuring W 140 XT 70 XH 80 cm - Illumination of 4 segments with a sunlight-like NS12 light spectrum - Illumination of a further 2 segments with a broadband red-blue light spectrum - Adaptation of the light sources for the cultivation of cyanobacteria in 24/7 operation, with simultaneous individual dimmability of the individual shelf compartments - Creation of a lighting concept for the intensity range 25 - 250 ?mol/m2/s to maximize the illumination homogeneity and minimize light pollution
