The collection of Myxobacteria at the Leibniz Institute DSMZ – German Collection of Microorganisms and Cell Cultures comprise 8,800 strains covering 50 species, 24 genera, 5 families and all four classes of the phylum Myxococcota Waite et al. 2021.
With the opening of the HZI/DSMZ Reichenbach collection in 2022 to the wider scientific community additional 5,800 strains of the unexplored part will become available for the scientific community. These strains are accompanied by a fantastic documentation and a collection of 2,800 specimens from all over the world sampled before 2014. Reichenbach, Dworkin, White and Rosenberg developed novel isolation and cultivation methods and paved the way for the isolation of novel Myxobacteria of broader taxonomic range.
Investigations by Mohr et al. and Octaviana et al. showed a huge diversity of novel species and genera among Sorangium and "Pseudowusel" strains from this collection (Mohr et al. 2018; Octaviana et al. 2022). We further investigated the genera "Pseudowusel" and "Wusel" by reactivating and classifying more than 200 strains. Surprisingly, we did observe strains of the described genera Dawidia and Pseudochryseolinea but also strains representing four novel genera and seven novel species. Another aspect is the successful isolation of novel taxa from the specimen collection as shown by Garcia et al. 2024. In a practical course, we confirmed successful isolation of Myxobacteria from soil samples from 1983.
To gather experts in the taxonomy of Myxobacteria (Myxococcota), the ICSP subcommittee on the taxonomy of Myxobacteria (Myxococcota) was established in 2022 (Hahnke et al. 2023). The subcommittee invites interested people to participate, provides expert knowledge on the current nomenclature, and define the minimal standards to describe new taxa within the phylum Myxococcota.
We present along with the diversity of Myxococcota at DSMZ, methods for long term preservation, give advice on depositing Myxobacteria at DSMZ (preservation, authentication), and show a glimpse on Reichenbach's documentation on specimens and strains.
