From: Antagonistic interactions between filamentous heterotrophs and the cyanobacterium Nostoc muscorum
Interactions between filamentous heterotrophs and autotrophs. Micrographs illustrating potential interactions between filamentous heterotrophs (black-gray filaments) and autotrophs (bigger bright cell-chains or cells). (a, b) BUZ 2 connected to Nostoc filaments or remaining cells in SM/BG11, (c) BUZ 3 free in SM/BG11 medium and connected to cyanobacterium (in the middle), (d) BUZ 2 in washed culture (without SM) breaking the Nostoc filament, (e) Bundle of BUZ 2 (washed) filaments covering and attaching to the autotroph, (f) Aggregate of BUZ 3 (washed) filaments covering short Nostoc filaments. Bar: 50 μm.
