Abstract
We present two strains affiliated with the GKS98 cluster. This phylogenetically defined cluster is representing abundant, mainly uncultured freshwater bacteria, which were observed by many cultivation-independent studies on the diversity of bacteria in various freshwater lakes and streams. Bacteria affiliated with the GKS98 cluster were detected by cultivation-independent methods in freshwater systems located in Europe, Asia, Africa and the Americas. The two strains, LF4-65T (=CCUG 56422T=DSM 107630T) and MWH-P2sevCIIIbT (=CCUG 56420T=DSM 107629T), are aerobic chemoorganotrophs, both with genome sizes of 3.2 Mbp and G+C values of 52.4 and 51.0 mol%, respectively. Phylogenomic analyses based on concatenated amino acid sequences of 120 proteins suggest an affiliation of the two strains with the family
Alcaligenaceae
and revealed
Orrella amnicola
and
Orrella marina
(=
Algicoccus marinus
) as being the closest related, previously described species. However, the calculated phylogenomic trees clearly suggest that the current genus
Orrella
represents a polyphyletic taxon. Based on the branching order in the phylogenomic trees, as well as the revealed phylogenetic distances and chemotaxonomic traits, we propose to establish the new genus Zwartia gen. nov. and the new species Z. hollandica sp. nov. to harbour strain LF4-65T and the new genus Jezberella gen. nov. and the new species J. montanilacus sp. nov. to harbour strain MWH-P2sevCIIIbT. Furthermore, we propose the reclassification of the species
Orrella amnicola
in the new genus Sheuella gen. nov. The new genera Zwartia, Jezberella and Sheuella together represent taxonomically the GKS98 cluster.

Environ Microbiol 2020; 22:1193-1206. [PMID: 31943686 DOI: 10.1111/1462-2920.14915] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2019] [Revised: 12/20/2019] [Accepted: 01/08/2020] [Indexed: 12/18/2022]
Abstract
The Asian tiger mosquito Aedes albopictus is a major public health concern because of its invasive success and its ability to transmit pathogens. Given the low availability of treatments against mosquito-borne diseases, vector control remains the most suitable strategy. The methods used thus far are becoming less effective, but recent strategies have emerged from the study of mosquito-associated microorganisms. Although the role of the microbiota in insect biology does not require further proof, much remains to be deciphered in mosquitoes, especially the contribution of the microbiota to host nutrient metabolism. Mosquitoes feed on plant nectar, composed of mostly fructose. We used stable isotope probing to identify bacteria and fungi assimilating fructose within the gut of Ae. albopictus. Mosquitoes were fed a 13 C-labelled fructose solution for 24 h. Differences in the active microbial community according to the sex of mosquitoes were highlighted. The bacterium Lelliottia and the fungi Cladosporium and Aspergillus dominated the active microbiota in males, whereas the bacterium Ampullimonas and the yeast Cyberlindnera were the most active in females. This study is the first to investigate trophic interactions between Ae. albopictus and its microbiota, thus underscoring the importance of the microbial component in nectar feeding in mosquitoes.

High-quality draft genome sequence of Gaiella occulta isolated from a 150 meter deep mineral water borehole and comparison with the genome sequences of other deep-branching lineages of the phylum Actinobacteria. Microbiologyopen 2019; 8:e00840. [PMID: 30977302 PMCID: PMC6741124 DOI: 10.1002/mbo3.840] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2019] [Revised: 03/04/2019] [Accepted: 03/05/2019] [Indexed: 01/25/2023] Open
Abstract
Gaiella occulta strain F2‐233T (=CECT 7815 = LMG 26412), isolated from a 150 meter deep mineral water aquifer, was deemed a candidate for high‐quality draft genome sequencing because of the rare environment from which it was isolated. The draft genome sequence (QQZY00000000) of strain F2‐233T is composed of approximately 3 Mb, predicted 3,119 protein‐coding genes of which 2,545 were assigned putative functions. Genome analysis was done by comparison with the other deep‐branching Actinobacteria neighbors Rubrobacter radiotolerans, Solirubrobacter soli and Thermoleophilum album. The genes for the tricarboxylic acid cycle, gluconeogenesis and pentose phosphate pathway, were identified in G. occulta, R. radiotolerans, S. soli and T. album genomes. Genes of the Embden–Meyerhof–Parnas pathway and nitrate reduction were identified in G. occulta, R. radiotolerans and S. soli, but not in the T. album genome. Alkane degradation is precluded by genome analysis in G. occulta. Genes involved in myo‐inositol metabolism were found in both S. soli and G. occulta genomes. A Calvin–Benson–Bassham (CBB) cycle with a type I RuBisCO was identified in G. occulta genome, as well. However, experimental growth under several conditions was negative and CO2 fixation could not be proven in G. occulta.

Abstract
Recognition and acknowledgment of novel bacterial taxonomy and nomenclature revisions can impact clinical practice, disease epidemiology, and routine clinical microbiology laboratory operations. The Journal of Clinical Microbiology (JCM) herein presents its biannual report summarizing such changes published in the years 2016 and 2017, as published and added by the International Journal of Systematic and Evolutionary Microbiology Noteworthy discussion centers around descriptions of novel Corynebacteriaceae and an anaerobic mycolic acid-producing bacterium in the suborder Corynebacterineae; revisions within the Propionibacterium, Clostridium, Borrelia, and Enterobacter genera; and a major reorganization of the family Enterobacteriaceae. JCM intends to sustain this series of reports as advancements in molecular genetics, whole-genome sequencing, and studies of the human microbiome continue to produce novel taxa and clearer understandings of bacterial relatedness.

Abstract
A bacterial strain designated KMB9T was isolated from a freshwater pond in Taiwan and characterized using a polyphasic taxonomy approach. Cells of strain KMB9T were Gram-stain-negative, aerobic, poly-β-hydroxybutyrate-accumulating, motile by means of a monopolar flagellum, non-spore-forming and rods surrounded by a thick capsule and forming white-coloured colonies. Growth occurred at 20-40 °C (optimum, 25-37 °C), at pH 6.5-7.5 (optimum, pH 7.0) and with 0-0.5 % NaCl (optimum, 0 %). Phylogenetic analyses based on 16S rRNA gene and four housekeeping gene sequences (recA, rpoA, rpoB and atpD) showed that strain KMB9T forms a distinct phyletic line within the family Alcaligenaceae, and the levels of 16S rRNA gene sequence similarity to its closest relatives with validly published names were less than 93.3 %. The predominant fatty acids were summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), C16 : 0 and C18 : 1ω7c. The major isoprenoid quinone was Q-8. The major polyamine was putrescine. The polar lipid profile revealed the presence of phosphatidylethanolamine, phosphatidylglycerol and several uncharacterized aminophospholipids, aminolipids, phospholipids and lipids. The genomic DNA G+C content of strain KMB9T was 54.5 mol%. On the basis of the genotypic and phenotypic data, strain KMB9T represents a novel species of a new genus in the family Alcaligenaceae, for which the name Parvibium lacunae gen. nov., sp. nov. is proposed. The type strain is KMB9T (=BCRC 81053T=LMG 30055T=KCTC 52814T).
