Abstract
-
Among the major bacterial secretions, outer membrane vesicles
(OMVs) are significant and highly functional. The proteins
and other biomolecules identified within OMVs provide
new insights into the possible functions of OMVs in bacteria.
OMVs are rich in proteins, nucleic acids, toxins and
virulence factors that play a critical role in bacteria-host interactions.
In this review, we discuss some proteins with multifunctional
features from bacterial OMVs and their role
involving the mechanisms of bacterial survival and defence.
Proteins with moonlighting activities in OMVs are discussed
based on their functions in bacteria. OMVs harbour many
other proteins that are important, such as proteins involved
in virulence, defence, and competition. Overall, OMVs are a
power-packed aid for bacteria, harbouring many defensive
and moonlighting proteins and acting as a survival kit in
case
of an emergency or as a defence weapon. In summary, OMVs can be defined as bug-out bags for bacterial defence and, therefore, survival. -

Abstract
- A nitrate-reducing Fe(II)-oxidizing bacterial strain, F8825T, was isolated from the Fe(II)-rich sediment of an urban creek in Pearl River Delta, China. The strain was Gram-negative, facultative chemolithotrophic, facultative anaerobic, nonspore- forming, and rod-shaped with a single flagellum. Phylogenetic analysis based on 16S rRNA gene sequencing indicated that it belongs to the genus Ciceribacter and is most closely related to C. lividus MSSRFBL1T (99.4%), followed by C. thiooxidans F43bT (98.8%) and C. azotifigens A.slu09T (98.0%). Fatty acid, polar lipid, respiratory quinone, and DNA G + C content analyses supported its classification in the genus Ciceribacter. Multilocus sequence analysis of concatenated 16S rRNA, atpD, glnII, gyrB, recA, and thrC suggested that the isolate was a novel species. DNA–DNA hybridization and genome sequence comparisons (90.88 and 89.86%, for values of ANIm and ANIb between strains F8825T with MSSRFBL1T, respectively) confirmed that strain F8825T was a novel species, different from C. lividus MSSRFBL1T, C. thiooxidans F43bT, and C. azotifigens A.slu09T. The physiological and biochemical properties of the strain, such as carbon source utilization, nitrate reduction, and ferrous ion oxidation, further supported that this is a novel species. Based on the polyphasic taxonomic results, strain F8825T was identified as a novel species in the genus Ciceribacter, for which the name Ciceribacter ferrooxidans sp. nov. is proposed. The type strain is F8825T (= CCTCC AB 2018196T = KCTC 62948T).
