2 October 2016 - LPSN is pleased to announce a new co-operation with bioinformatics company Ribocon (www.ribocon.com). Ribocon is a provider of DNA analysis for species identification and community profiling, with emphasis on digital management of taxonomic information and partner of the ribosomal genes database SILVA (www.arb-silva.de). Ribocon will be supporting LPSN by means of optimizing the database infrastructure and applying extra quality control procedures to improve system sustainability over time.
The classfication of domains and phyla page has been thoroughly updated in collaboration with Pablo Yarza from Ribocon.
