We had 6 Petridishes that contained our medium and our pipette could collect 3 ml of liquid. As a first step, we blended a piece of the Kombucha skin with 0.5 ml of distilled water and poured a drop onto our first dish. The first 0.5 ml of bacteria-solution was diluted further | |||
We emptied the pipette again till we regained the amount of 0.5 ml and added another 2.5 ml of distilled water. | :We had 6 Petridishes that contained our medium and our pipette could collect 3 ml of liquid.

We could observe how the Gluconacetobacter colonies arranged differently according to its concentration on the petridish. | |||
