Florilege : a database gathering microbial phenotypes of food interest

Abstract : Food fermentation and biopreservation processes involve the use of various species and strains of bacteria and yeast. These strains are responsible for the targeted qualities of the food products that are sanitary, organoleptic (aroma and texture) and healthy qualities. The Florilege database project aims at (i) gathering bacterial and yeast phenotypes of food product of interest that are automatically extracted from PubMed-referenced full-text litterature by using a text mining approach (ii) managing the information in a relational database (iii) enabling multi-criteria requests via a Web user-friendly interface. To date 368 phenotypes, 260 synthetised or degraded molecules, 1076 medium or food products, 1181 bacterial taxons have been acquired by a combinaison of automatic and manual annotations of text, used for training the text-mining method. Food products are automatically categorized in Florilege according to the OntoBiotope ontology that we have extended with dairy and bakery products definitions. Taxa are categorized by the NCBI taxonomy. An ontology of microbial characteristics has been specifically enriched by the Florilege project. This ontology defines microbial phenotypes (Ontobiotope-Phenotype), including intracellular characteristics of cells (such as shape, antibiotic resistance...) and microbial uses (Ontobiotope-Use) that express the microbial alteration of the external environment, food or matrix, such as aroma, vitamin or other molecule production, degradation or food coloring. A preliminary Web interface is available for querying taxa, culture medium and food products at http://genome.jouy.inra.fr/Florilege/. The public availability of Florilege database is planned for the end of 2017 with a user-friendly interface for multi-criteria requests and access to various phenotypes. Florilege will be a highly valuable tool to (i) assess phenotypic biodiversity of food microbes (ii) assign biochemical functions to each strain/species from fermented or biopreserved food products (iii) help into the development of innovative food products in particular those that involve fermentation or biopreservation processes.
