Bacteria-based multicellular Organism

Is it possible for Bacteria to evolve into multicellular organisms like what happened to Animals, Fungi and Plants?
 
How do you think we became multicelular?

Actually.. Not.

Bacterias are NOT the cells we are made of, but an earlier branch of life, the... Procaryotes(?). We descend from a more recent branch, when some cells like bacterias got a real nucleus, grew up and all - Eucartyotes.

There are unicellular eucaryotes. If my knowledge is correct, multicellular beings began as unicellular "colonies", so to speak, which then differentiated creating different tissues.
A multicellular procaryote? Would it have any evolutionary advantage over a eucaryote?

In part they did. The eukaryote cell originated as symbiotic relationship between an archean cell and an internal symbiotic bacterium. Mitochondria and chloroplasts are known to be descended from these symbiotic bacteria. There are also questions over whether the cell nucleus is also descended from a symbiotic bacteria

While I'm sure there will be people who will object to this answer on the basis that they consider the 'main' archean cell to be purely what we have evolved from I would point out that both the archea and bacteria derived portions of the eukaryote cell are essential and you cannot separate them out. We are derived from both

We have also partially evolved from numerous retroviruses. For instance it seems likely that several genes that are active in the placenta are of retroviral origin.
 
There may be biological reasons to why the Eucaryotes did it but not their simpler parents... Any microbiologist around?

Bacteria didn't have the time for such nonsense.

No, seriously. The space and energy constraints, and the high turnover of a non-eukaryotic cell means that there is little genomic space or time for experiments like multicellularity.

There are some bacteria with more complex colonial formations, plus filamentous bacteria like the Actinobacteria with more complex internal structuring, but those are all transient phenomena, despite billions of years of evolution.

Also talking about prokaryotes being the parents of Eukaryotes is stupid. The stuff around right now is pretty different from the LCA, and they're as highly evolved (or rather more highly evolved) for their niche as the Eukaryotes are for theirs.

*Edit: calling the myxobacteria multicellular is a bit of stretch, since there is no differentiation in their fruiting bodies (unlike slime moulds), and in normal operation the cells are close, not continuous.
