As each half hour passes, the colony of bacteria doubles. Initially, the numbers are fairly low, but the amounts become larger and larger as they compound.
Hour 0- 1
Hour 0.5- 2
Hour 1- 4

Hour 2- 16
Hour 2.5- 32
By hour 10, the bacteria will have increased to 1048576. By hour 15, the number of bacteria will be 1073741824. By hour 24, the colony will contain 281474976710656 bacteria.
