Under optimal growth conditions the doubling time for E. coli is 20 minutes. This is however, a textbook figure and in practice the doubling time is slightly longer. Under standard, non-bioreactor type laboratory conditions, aerated (shaking) E coli cultures grown in LB or similar media will have a doubling time of around 30 minutes. Note that growth rates differ between strains, B strain derivatives (often used for protein expression) grow faster than K strain derivatives (generally used for cloning). Also, strains harboring plasmids and strains grown under selective pressure will often have longer doubling times.
The doubling time is around 26 minutes.
The average doubling time of lactobacillus acidophilus is 1.8 hours at 40 degrees centigrade.

Ecoli. with out Ecoli in our digestive system, we would not be able to process our food the right way. They help us live, we give them a home. this is not to say that Ecoli is harmless. It will kill you if it ends up in the wrong part of your body; but most of the time it just chills in the large intestine.
