Let's assume you start with one bacterium:

Step by step this gives you:

½ hour: 2

1 hour: 4

1½ hours: 8

2 hours: 16

2½ hours: 32

3 hours: 64

3½ hours: 128

4 hours: 256

You will notice that the number doubles each hour. So you can just apply the formula: bacteria = 2t, where t is the number of time periods. In this case we have 8 half-hours, so that's 28, or 256.

After twenty four hours how many bacteria can be produced?

It depends on the species of bacteria as some divide more rapidly than others.


If a certain bacterium divides every 30 min when will there be more than 1000 bacteria?

It would take 5 hours to get over 1000.


How many Bacteria are produced after 12 hours?

There were 20000*(1+340/100) = 20000*4.4 = 88000


If a bacterium divides every 30 minutes producing two bacteria how many bacteria would a single colony contain after 24 hours if it began as a single bacterium?

I would say 2,361,183,241,434,822,606,848 based on: every 20 minutes for 24 hours = 72 times "doubling" after the initial doubling of 1 to 2, that leaves 71 more times, so the equation should be 271 = 2,361,183,241,434,822,606,848 ~= 2.36118324 × 1021
