Two Gram-stain-negative, curved-rod-shaped, non-motile and aerobic bacteria W6 and I13 were isolated from marine sediment samples collected from Meishan Island located in the East China Sea. Catalase and oxidase activities and hydrolysis of Tween 40, 60 and 80 were positive for both strains, while nitrate reduction, indole production, methyl red reaction and HS production were negative. Phylogenetic analyses based on 16S rRNA and genome sequences revealed that strains W6 and I13 formed distinct phylogenetic lineages within the genera and , respectively.

The protection of steel based on microbial biomineralization has emerged as a novel and eco-friendly strategy for corrosion control. However, the molecular basis of the biomineralization process in mineralization bacteria remains largely unexplored. We previously reported that EPS+ strain provides protection against steel corrosion by forming a hybrid biomineralization film.

A novel aerobic marine bacterium, FRT2, isolated from surface water of a fishing port in Fukui, Japan, was characterised based on phylogenomic and phylogenetic analyses combined with classical phenotypic and chemotaxonomic characterisations. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain FRT2 clustered with genus Leeuwenhoekiella. Closest relatives of FRT2 were Leeuwenhoekiella palythoae KMM 6264 and Leeuwenhoekiella nanhaiensis G18 with 16S rRNA gene sequence identities of 95.

Vibrio anguillarum is a pathogen responsible for vibriosis in aquaculture animals. The formation of bacterial biofilm contributes to infections and increases resistance to antibiotics. Tryptophanase and its substrate tryptophan have been recognized as signal molecules regulating bacterial biofilm formation.
