Zobellia galactanivorans is a gram-negative marine bacterium isolated from the surface of red algae of the coast of France.

Z. galactanivorans forms yellow colonies with a bacillus or diplobacillus morphology.

Furthermore, it is mesophilic and can grow degrade carrageenans and agars - both found in the cell wall of red algae.

[2] porA and porB are catalytic enzymes that hydrolyze the β-D-galactopyranose (1→4) α-L-galactopyranose-6-sulfate linkage in porphyran.

[3] Moreover, porphyranase genes in both Z. galactanivorans and B. plebeius are located in similar orders along their chromosome, or are syntenic.
