Antunes VDC, Freitag D, Serrato RV. Differential exopolysaccharide production and composition by Herbaspirillum strains from diverse ecological environments. Arch Microbiol 2021; 203:3883-3892. [PMID: 34009446 DOI: 10.1007/s00203-021-02371-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 04/22/2021] [Accepted: 05/08/2021] [Indexed: 11/26/2022]
Abstract
Bacteria belonging to the genus Herbaspirillum are found in many different ecological niches. Some species are typically endophytic, while others were reported as free-living organisms that occupy various environments. Also, opportunistic herbaspirilli have been found infecting humans affected by several diseases. We have analyzed the production of exopolysaccharides (EPS) by Herbaspirillum strains isolated from different sources and with distinct ecological characteristics. The monosaccharide composition was determined for the EPS obtained for selected strains including free-living, plant-associated and clinical isolates, and the relationship with the ecological niches occupied by Herbaspirillum spp. is proposed.

[PMID: 33063170 DOI: 10.1007/s00203-020-02076-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2020] [Revised: 09/21/2020] [Accepted: 10/01/2020] [Indexed: 10/23/2022]
Abstract
A Gram-stain-negative, aerobic, non-motile and yellow-colored bacterium, strain 17J57-3 T, was isolated from soil collected in Pyeongchang city, Korea. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain 17J57-3 T formed a distinct lineage within the family Oxalobacteraceae (order Burkholderiales, class Betaproteobacteria). Strain 17J57-3 T was the most closely related to Noviherbaspirillum humi U15T (96.4% 16S rRNA gene sequence similarity) and Noviherbaspirillum massiliense JC206T (96.2%). The draft genome size of strain 17J57-3 T was 6,117,206 bp. Optimal growth occurred at 30 °C, pH 7.0 without NaCl. The predominant cellular fatty acids were summed feature 3 (C16:1 ω6c/C16:1 ω7c) and C16:0. The major respiratory quinone was Q-8. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. Biochemical, chemotaxonomic and phylogenetic analyses indicated that strain 17J57-3 T represents a novel bacterial species within the genus Noviherbaspirillum, for which the name Noviherbaspirillum galbum is proposed. The type strain of Noviherbaspirillum galbum is 17J57-3 T (= KCTC 62213 T = NBRC 114384 T).
