Pilot study: what bacteria did we find?

The individual results from each soil sample are included within the Epicollect5 project page with interactive map. Results are given in a data table with pie charts showing the top five phyla of bacteria present along with the percentage of other bacterial phyla including Firmicutes (this phylum is a known source of antibiotics).

We found the same top five phyla of bacteria in all soil samples (Proteobacteria, Bacteroidetes, Actinobacteria, Acidobacteria and Verrucomicrobia). Firmicutes were also present but in very small amounts. Although some experiments were carried out by pupils, the pilot study did not formally record environmental data such as soil temperature, pH, moisture content etc. Environmental data will be recorded for all future soil samples.

Here is an example pie chart. It shows the results for the sample taken from the vegetable patch at Greyfriars Primary School. This sample is also the one with the greatest diversity of bacteria!

The total number of unique species of bacteria identified in each of the soil samples from our pilot study is shown in the bar chart below:
