Bakterie

Blandt de symbiotiske bakterier findes adskillige, blandt andet Streptococcus Faecium Endococcus Faecium Enterococcus Bifido

Desuden mener man at blågrønalgerne (cyanobakterier) regnes for at være stamformen til de højere planters grønkorn. Man mener, at en flercellet organisme engang har ædt en blågrønalge, men ladet være med at fordøje den, så den i stedet blev anbragt i cellen som et grønkorn.

Tilsvarende er en bakterie blevet ædt, men ikke fordøjet. Den fungerer i dag som planters og dyrs mitochondrie (organel, der omsætter druesukker og frigiver energibærende ATP-molekyler)

• January 07 2005, iol: Pollution-eating bugs found in sewage sludge Citat: "...They published the genetic sequence of the bug, called Dehalococcoides ethenogenes Strain 195, and said it showed some surprising flexibility...Different strains break down perchloroethylene or PCE, a chlorinated solvent used for dry cleaning; trichloroethylene, used to clean metal parts; chlorobenzenes, used to produce the now-banned pesticide DDT; and polychlorinated biphenyls or PCBs, compounds that were once used as coolants and lubricants in transformers..."Just by picking up these mobile genetic elements from other bacteria, Dehalococcoides strains seem able to adapt and to take advantage of opportunities as they present themselves," Zinder said in a statement. The researchers said their findings suggest the bacteria may have developed the ability to munch chlorinated solvents fairly recently, the researchers said...."
