Fig. 4From: Light in the box—photobiological examination chamber with light trap ventilation system for studying fungal surface cultures illustrated with Metarhizium brunneum and Beauveria brongniartii Colony appearance of M. brunneum grown on S4G medium in dependence of different irradiation regimes. Cultures were cultivated for 2 weeks either in complete darkness or exposed to blue light (λpeak = 452 nm), green light (λpeak = 519 nm) or red light (λpeak = 635 nm). Corresponding illumination intensities in µW cm-2 are given in Additional file 1: Table S3. Per condition, a typical colony is shownBack to article page
