Stereomicroscopic and differential interference contrast (DIC) images of 48 h submerged cultivations of the filamentous fungus Aspergillus niger

The dataset provides 2694 stereomicroscopic 8-bit RGB JPEG images of 44 sampling times from two 48 h submerged cultivations of the filamentous fungus Aspergillus niger. The cultivations were performed in shake flasks with identical cultivation parameters. About 1300 images were taken for each cultivation flask. At least 24 images per culture and sampling time were taken. The stereomicroscopic images depict the development of Aspergillus niger pellets starting from the agglomeration of spores after inoculation followed by spore germination and outgrowth into a pellet population. The following pixel sizes and field of views (FoV) were used at the different sampling times: 0 h – 1.5 h, pixel size 0.82 µm, FoV 1.49 mm × 1.12 mm; 2 h – 2.5 h, pixel size 1.63 µm, FoV 2.97 mm × 2.22 mm; 3 h – 3.5 h, pixel size 3.33 µm, FoV 6.07 mm × 4.55 mm; 4 h – 48 h, pixel size 4.08 µm, FoV 7.44 mm × 5.58 mm.
