DNA metabarcoding as a novel quality control method for industrial yeast starter cultures

In a recent study, a new tool was developed and tested with the help of our DNA metabarcoding service. DNA metabarcoding has proven to be a major step forward in the quick and effective detection of multiple species of yeast in one sample with unknown composition, and thus represents a  promising tool for non-targeted quality control of yeast starter cultures.


We are currently developing new projects which will aim to improve and refine the metabarcoding approach for yeast cultures further by testing additional genetically diverse regions, such as internal transcribed spacers (e.g. ITS1).

First evidence of the barred grass snake in Bavaria with DNA Barcoding 

Researchers from the Bavarian State Collection of Zoology have discovered a previously overlooked snake species in Bavaria. It is a special form of barred grass snake (Natrix helvetica), which was previously known only from the Southern Alps and is apparently also widespread in western Austria. With the DNA barcoding service of AIM, the species could be specifically reported for Bavaria.

DNA Metabarcoding supports Europe-wide biodiversity study in beech forests

Much of Europe is covered by beech forests (dominated by beech trees Fagus sylvatica). These forests provide a livelihood for many species, including thousands of arthropods. Mushrooms are an important component of functioning forests and are the most important organisms for wood decomposition. The fruit bodies and mycelia of fungi are an important source of food for many insects and other arthropods.


Therefore, the tinder fungus and the associated diversity of arthropods have been investigated in a recent study by Friess et al. (2018). AIM supported this study with their DNA metabarcoding service.

Pests in the warehouse - DNA barcoding uncovers!

Especially when it comes to claims for damages by pests, identification must often be quick and above all accurate. As in the following case, in the summer of 2018 BIO-TECH was able to protect an important customer from high demands with the aid of AIM and our DNA barcoding service.

Integrative Taxonomy as a tool for the determination of species of the smaller arachnid orders

Integrative taxonomy combines morphological species determination by means of classical taxonomy with modern methodological developments like COI DNA barcoding. This helps to recheck species boundaries or search for cryptic species previously undetected by morphological analysis.


In a recent study from 2018 AIM could support in the determination of species of the smaller arachnid orders in Peru using integrative taxonomy.
