A new DNA marker family for microbial identification for food and analytical sectors

Country of Origin: Italy
Reference Number: TOIT20190304001
Publication Date: 4 March 2019

Summary

An Italian biotech company has developed a new family of DNA markers which offers the possibility to differentiate and identify phylogenetically closed bacterial species and subspecies even in mix. The company has already filled an international patent application and now it is looking for strategic partners in food and analytical sectors for the development of new kits and applications and their commercialisation through technical cooperation and licensing agreements.

Description

Microbial identification is still a challenge. Actual methods like as 16S, multilocus sequence typing (MLST) or Next Gen Sequencing (NGS) have major drawbacks like accuracy (e.g. 16S is unable to sort out closely related species), costs and time (e.g. MLST takes days with relatively high costs, and NGS is no better), but the main issue is that none of these methods is really effective when a mix is under scrutiny. 
The biotech company from northern Italy has developed a new family of DNA markers which offers the possibility to differentiate and identify phylogenetically closed bacterial species and subspecies even in mix.
These new markers are effective in differentiating and identifying microorganisms thanks to both sequence (Single Nucleotide Polymorphisms - SNPs) and length polymorphism (insertions/deletions). Moreover, these markers share high sequence variability with protein coding genetic markers (e.g. those applied in MLST), that is useful to identify closely related species and subspecies and also to differentiate strains that group together with MLST. Companies working in food and analytical sectors are sought to develop new diagnostic kits and/or use this technology in applications relevant for their businesses, through technical cooperation and licensing agreements.

Advantages and Innovations

The new markers family is an highy customizable, low cost, multi-platform tool for the identification and quantification of:

- lactobacilli, bifidobacteria and spore-forming bacilli included in the most common probiotic products, even when they are in multi-strain mix.

- spore forming bacilli commonly applied in agriculture as bio-fertilizers and bio-pesticides.

- other micro-organisms of interests

Stage Of Development

Already on the market

Stage Of Development Comment

The product is at minimum viable product (MVP) stage with some applications already available. Customized solutions could be developed on demand with specific requirements.

Requested partner

Companies working in food and analytical sector interested in developing and/or using this technology in applications relevant for their businesses are sought for technical cooperation and licensing agreements.
