The hidden world of bacteria
Exploring the diversity of bacteria in Austrian inland waters: isolation and description of new species
The topic of the project ‚The hidden world of bacteria‘ was the diversity of bacteria in local inland waters. When asked on the street where they would look for undiscovered species, people would answer „in the tropics“, „in the rain forest“ or „in the deep ocean“. Asked for groups with great numbers of novel species, frequent answers would probably be „insects“, „fishes“ and „orchids“. It is widely unknown that our direct surrounding, for example the flower pot on the window bench or the nearby lake, contains a lot of not scientifically registered species. According to one of several estimations 99% of the about one million bacteria species are not scientifically described.
For this reason, the aim of the project was to isolate and describe new bacteria species from surrounding inland waters with the assistance of students. The subsequent investigation and characterisation of the new species included sequencing of the genomes. Genome sequences are of great importance to link the taxonomic research with the investigation of the microbial diversity and ecology. Students from six classes from five high schools with focus on natural science took samples from different waters. Together with the project team they cultivated and isolated from this samples bacterial strains. Some of the students contributed to the phenotypical characterisation, the analysis of the data and the description of the taxa. From the samples of each class at least one new species was described in the time frame of the project. Every class was able to attend the complete process from the isolation to the description of their bacteria species. Materials like video animations and instructions for experiments were shared on a web page where furthermore the progress of the project was documented.
This project has been completed.
