European Natural Science collections contain around 1.5 billion specimens representing an estimated 55% of global collections and 80% of the worlds bio- and geo-diversity. Data derived from these collections underpin countless innovations, including tens of thousands of scholarly publications, products critical to our bio-economy, databases, maps and descriptions of scientific observations.

Volunteer Stephen Chandler tells us how he has been supporting The Microverse project by using computer software to identify the taxonomic groupings of the DNA sequences revealed in the sequencing machine.
Due to the size of microorganisms, we have until recent years relied on microscopes to identify different species. The advancement of scientific technologies however has made it possible for scientists to extract DNA from microorganisms, amplify that DNA into large quantities and then put the samples into a sequencing machine to reveal the genetic sequences. In The Microverse project, my role begins when the sequencer has finished processing the samples.
When the gene sequencer has finished decoding the PCR products it creates a file much like a typical excel file. The main difference is that this file can be incredibly large as it contains millions of DNA sequences belonging to hundreds if not thousands of species. This requires a powerful computer to run the analysis to identify what is in the sample.
