Received: 27 November 2019; Accepted: 9 January 2020; Published: 10 January 2020 Abstract: Members of the Microvirga genus are metabolically versatile and widely distributed in Nature. However, knowledge of the bacteria that belong to this genus is currently limited to biochemical characteristics. Herein, a novel thermo-tolerant bacterium named Microvirga thermotolerans HR1 was isolated and identified. Based on the 16S rRNA gene sequence analysis, the strain HR1 belonged to the genus Microvirga and was highly similar to Microvirga sp. 17 mud 1-3. The strain could grow at temperatures ranging from 15 to 50 ◦C with a growth optimum at 40 ◦C. It exhibited tolerance to pH range of 6.0–8.0 and salt concentrations up to 0.5% (w/v). It contained ubiquinone 10 as the predominant quinone and added group 8 as the main fatty acids. -
Diversion and Phylogenetic Relatedness of Filterable Bacteria from Norwegian Tap and Bottled Waters
Diversion and phylogenetic relatedness of filterable bacteria from Norwegian tap and bottled waters Short title: Filterable bacteria in Norwegian tap and bottled waters Colin Charnock*, Ralf Xue Hagen, Theresa Ngoc-Thu Nguyen, Linh Thuy Vo Department of Life Sciences and Health, Oslo Metropolitan University, NO-0130, Oslo, Norway *Corresponding author. E-mail address: [email protected]. ABSTRACT Numerous articles have documented the existence of filterable bacteria. Where filtration is the chosen method of sterilization for medicinal or media components, these bacteria will by definition render products non-sterile. They may further represent a health hazard to the end user. A wide-range of bacterial genera were found in bottled and tap water filtrates from 0.2 µm filters, including genera housing opportunistic pathogens (e.g. Methylobacterium) and endospore formers (Paenibacillus). Two municipal tap water isolates were only distantly related to named species. One of these grew on agar, and could potentially provide hitherto unharvested useful biological products. The other grew only in water, and failed to produce colonies on media targeting either heterotrophs or autotrophs. The present study is one of very few looking at filterable bacteria in bottled waters intended for human consumption and the first identifying the filterable portion. It extends the range of known habitats of filterable bacteria and provides data on two new or novel species. Key words │bottled water, filterable bacteria, new species ©IWA Publishing 2019.

Characterization of Bacterial Communities Associated
www.nature.com/scientificreports OPEN Characterization of bacterial communities associated with blood‑fed and starved tropical bed bugs, Cimex hemipterus (F.) (Hemiptera): a high throughput metabarcoding analysis Li Lim & Abdul Hafz Ab Majid* With the development of new metagenomic techniques, the microbial community structure of common bed bugs, Cimex lectularius, is well‑studied, while information regarding the constituents of the bacterial communities associated with tropical bed bugs, Cimex hemipterus, is lacking. In this study, the bacteria communities in the blood‑fed and starved tropical bed bugs were analysed and characterized by amplifying the v3‑v4 hypervariable region of the 16S rRNA gene region, followed by MiSeq Illumina sequencing. Across all samples, Proteobacteria made up more than 99% of the microbial community. An alpha‑proteobacterium Wolbachia and gamma‑proteobacterium, including Dickeya chrysanthemi and Pseudomonas, were the dominant OTUs at the genus level. Although the dominant OTUs of bacterial communities of blood‑fed and starved bed bugs were the same, bacterial genera present in lower numbers were varied. The bacteria load in starved bed bugs was also higher than blood‑fed bed bugs. Cimex hemipterus Fabricus (Hemiptera), also known as tropical bed bugs, is an obligate blood-feeding insect throughout their entire developmental cycle, has made a recent resurgence probably due to increased worldwide travel, climate change, and resistance to insecticides1–3. Distribution of tropical bed bugs is inclined to tropical regions, and infestation usually occurs in human dwellings such as dormitories and hotels 1,2. Bed bugs are a nuisance pest to humans as people that are bitten by this insect may experience allergic reactions, iron defciency, and secondary bacterial infection from bite sores4,5. -

We identified bacterial communities associated with the heads of surface-sterilized insect vectors of X. fastidiosa subsp. pauca that were collected from CVC affected citrus groves in Brazil. Bacteria were isolated and analyzed by amplified ribosomal DNA restriction analysis (ARDRA) and sequencing, revealing the presence, among the most abundant genera, of the well-known citrus endophytes Methylobacterium spp. -
A Primary Assessment of the Endophytic Bacterial Community in a Xerophilous Moss (Grimmia Montana) Using Molecular Method and Cultivated Isolates
Brazilian Journal of Microbiology 45, 1, 163-173 (2014) Copyright © 2014, Sociedade Brasileira de Microbiologia ISSN 1678-4405 www.sbmicrobiologia.org.br Research Paper A primary assessment of the endophytic bacterial community in a xerophilous moss (Grimmia montana) using molecular method and cultivated isolates Xiao Lei Liu, Su Lin Liu, Min Liu, Bi He Kong, Lei Liu, Yan Hong Li College of Life Science, Capital Normal University, Haidian District, Beijing, China. Submitted: December 27, 2012; Approved: April 1, 2013. Abstract Investigating the endophytic bacterial community in special moss species is fundamental to under- standing the microbial-plant interactions and discovering the bacteria with stresses tolerance. Thus, the community structure of endophytic bacteria in the xerophilous moss Grimmia montana were esti- mated using a 16S rDNA library and traditional cultivation methods. In total, 212 sequences derived from the 16S rDNA library were used to assess the bacterial diversity. Sequence alignment showed that the endophytes were assigned to 54 genera in 4 phyla (Proteobacteria, Firmicutes, Actinobacteria and Cytophaga/Flexibacter/Bacteroids). Of them, the dominant phyla were Proteobacteria (45.9%) and Firmicutes (27.6%), the most abundant genera included Acinetobacter, Aeromonas, Enterobacter, Leclercia, Microvirga, Pseudomonas, Rhizobium, Planococcus, Paenisporosarcina and Planomicrobium. In addition, a total of 14 species belonging to 8 genera in 3 phyla (Proteo- bacteria, Firmicutes, Actinobacteria) were isolated, Curtobacterium, Massilia, Pseudomonas and Sphingomonas were the dominant genera. Although some of the genera isolated were inconsistent with those detected by molecular method, both of two methods proved that many different endophytic bacteria coexist in G. montana. According to the potential functional analyses of these bacteria, some species are known to have possible beneficial effects on hosts, but whether this is the case in G. -

PhoD and PhoX alkaline phosphatases and AcpA acid phosphatase are produced by microorganisms in response to phosphorus limitation in the environment. In this thesis, the current knowledge of the prevalence of phoD and phoX in the environment and of their taxonomic distribution was assessed, and new molecular tools were developed to target the phoD and phoX alkaline phosphatase genes in soil microorganisms. -
