Bacteria question?

Hi guys what bacteria consumes other bacteria...do you guys know the answer to this??

Bacteria question?
Yes, they are predatory bacteria. These bacteria are not well characterized. The most well known obligate predatory bacteria group is the Bdellovibrio-and-like organisms (BALO) but are not the only type. Other types include, Myxococalles Lysobacter, Micavibrio, and Vampirococcus (my personal favorite).





BALO are small, highly motile gram negative bacteria that obligatory prey on other gram negative bacteria. Their typical life cycle includes the free swimming cell invading the periplasm of the prey, growth, replication, and then differentiate to progeny cells that lyse the host cell.
Reply:Most bacteria I know about don't actually "consume" things the way white blood cells or amoebas do. Bacterial cell walls are too rigid to stretch around another cell. Bacteria feed by secreting digestive enzymes which break down food. Once broken down, the bacteria then re-absorb the food molecules. For bacteria to feed on other bacteria, the preditory species would release a substance which broke down the walls of the prey species. This is how fungi feed on bacteria. Penicillin has a special enzyme which breaks down the cell walls of bacteria.
Reply:is it bacteriophage
Reply:i dont think that any bacteria feeds on other bacteria.





btw, bacteriophage is a virus, not a bacterium!!!
