Poribacteria
Poribacteria are a candidate phylum of bacteria originally identified in the microbiome of sea sponges (''Porifera''). Poribacteria were distinguished from other microorganisms associated with sea sponges by their distinctive morphology featuring a large membrane-bound cellular compartment that frequently contains DNA, a highly unusual feature for a prokaryote. Poribacteria are Gram-negative mixotrophs.
==Genome==
Single-cell genomics analysis of poribacteria reveals a genome with a lower size bound of 1.88 megabases and 1585 protein-coding genes, of which an unusually high 24% have no homology to known genes. Among the genes of identifiable homology, genetic infrastructure can be identified for aerobic metabolism, denitrification and urea uptake, and carbon fixation through the Wood-Ljungdahl pathway.〔
The poribacterial genome is also reported to contain an unusually high number of phyH-domain proteins, which are enzymes involved in oxidative reactions. The functional significance of this observation is not known.
