Are bacteria immortal?

Scientists believe the cycle can repeat indefinitely, rendering it potentially immortal. … In fact, bacteria are also said to be biologically immortal, but only at the level of the colony, since the two daughter bacteria resulting from cell division of a parent bacterium can be regarded as unique individuals.] 2.
