Lists of Names of Prokaryotic Candidatus Taxa
NOTIFICATION LIST: CANDIDATUS LIST NO. 1 Oren et al., Int. J. Syst. Evol. Microbiol. DOI 10.1099/ijsem.0.003789 Lists of names of prokaryotic Candidatus taxa Aharon Oren1,*, George M. Garrity2,3, Charles T. Parker3, Maria Chuvochina4 and Martha E. Trujillo5 Abstract We here present annotated lists of names of Candidatus taxa of prokaryotes with ranks between subspecies and class, pro- posed between the mid- 1990s, when the provisional status of Candidatus taxa was first established, and the end of 2018. Where necessary, corrected names are proposed that comply with the current provisions of the International Code of Nomenclature of Prokaryotes and its Orthography appendix. These lists, as well as updated lists of newly published names of Candidatus taxa with additions and corrections to the current lists to be published periodically in the International Journal of Systematic and Evo- lutionary Microbiology, may serve as the basis for the valid publication of the Candidatus names if and when the current propos- als to expand the type material for naming of prokaryotes to also include gene sequences of yet-uncultivated taxa is accepted by the International Committee on Systematics of Prokaryotes. Introduction of the category called Candidatus was first pro- morphology, basis of assignment as Candidatus, habitat, posed by Murray and Schleifer in 1994 [1]. The provisional metabolism and more. However, no such lists have yet been status Candidatus was intended for putative taxa of any rank published in the journal. that could not be described in sufficient details to warrant Currently, the nomenclature of Candidatus taxa is not covered establishment of a novel taxon, usually because of the absence by the rules of the Prokaryotic Code. -

Chemosynthetic and Photosynthetic Bacteria Contribute Differentially to Primary Production Across a Steep Desert Aridity Gradient

Bay ● David W. Waite ● Xiyang Dong ● Osnat Gillor ● Steven L. Chown ● 3 1,2 Philip Hugenholtz ● Chris Greening Received: 23 November 2020 / Revised: 16 April 2021 / Accepted: 28 April 2021 © The Author(s) 2021. This article is published with open access Abstract Desert soils harbour diverse communities of aerobic bacteria despite lacking substantial organic carbon inputs from vegetation. A major question is therefore how these communities maintain their biodiversity and biomass in these resource-limiting ecosystems. Here, we investigated desert topsoils and biological soil crusts collected along an aridity gradient traversing four climatic regions (sub-humid, semi-arid, arid, and hyper-arid). Metagenomic analysis indicated these communities vary in their capacity to use sunlight, organic compounds, and inorganic compounds as energy sources. Thermoleophilia, Actinobacteria, and Acidimicrobiia 1234567890();,: 1234567890();,: were the most abundant and prevalent bacterial classes across the aridity gradient in both topsoils and biocrusts. Contrary to the classical view that these taxa are obligate organoheterotrophs, genome-resolved analysis suggested they are metabolically flexible, withthecapacitytoalsouseatmosphericH2 to support aerobic respiration and often carbon fixation. In contrast, Cyanobacteria were patchily distributed and only abundant in certain biocrusts. Activity measurements profiled how aerobic H2 oxidation, chemosynthetic CO2 fixation, and photosynthesis varied with aridity. Cell-specific rates of atmospheric H2 consumption increased 143-fold along the aridity gradient, correlating with increased abundance of high-affinity hydrogenases. Photosynthetic and chemosynthetic primary production co-occurred throughout the gradient, with photosynthesis dominant in biocrusts and chemosynthesis dominant in arid and hyper-arid soils. -

Characterizing the Fecal Microbiota and Resistome of Corvus Brachyrhynchos (American Crow) in Fresno and Davis, California
ABSTRACT CHARACTERIZING THE FECAL MICROBIOTA AND RESISTOME OF CORVUS BRACHYRHYNCHOS (AMERICAN CROW) IN FRESNO AND DAVIS, CALIFORNIA American Crows are common across the United States, well adapted to human habitats, and congregate in large winter roosts. We aimed to characterize the bacterial community (microbiota) of the crows’ feces, with an emphasis on human pathogens. The antibiotic resistance (AR) of the bacteria was analyzed to gain insight into the role crows may play in the spread of AR genes. Through 16S rRNA gene and metagenomic sequencing, the microbiota and antibiotic resistance genes (resistome) were determined. The core microbiota (taxa found in all crows) contained Lactobacillales (22.2% relative abundance), Enterobacteriales (21.9%) and Pseudomonadales (13.2%). Among the microbiota were human pathogens including Legionella, Camplycobacter, Staphylococcus, Streptococcus, and Treponema, among others. The Fresno, California crows displayed antibiotic resistance genes for multiple drug efflux pumps, macrolide-lincosamide- streptogramin (MLS), and more. Ubiquitous, urban wildlife like the American Crow may play a role in the spread of AR pathogens to the environment and human populations.

Taxonomic Hierarchy of the Phylum Proteobacteria and Korean Indigenous Novel Proteobacteria Species
Journal of Species Research 8(2):197-214, 2019 Taxonomic hierarchy of the phylum Proteobacteria and Korean indigenous novel Proteobacteria species Chi Nam Seong1,*, Mi Sun Kim1, Joo Won Kang1 and Hee-Moon Park2 1Department of Biology, College of Life Science and Natural Resources, Sunchon National University, Suncheon 57922, Republic of Korea 2Department of Microbiology & Molecular Biology, College of Bioscience and Biotechnology, Chungnam National University, Daejeon 34134, Republic of Korea *Correspondent: [email protected] The taxonomic hierarchy of the phylum Proteobacteria was assessed, after which the isolation and classification state of Proteobacteria species with valid names for Korean indigenous isolates were studied. The hierarchical taxonomic system of the phylum Proteobacteria began in 1809 when the genus Polyangium was first reported and has been generally adopted from 2001 based on the road map of Bergey’s Manual of Systematic Bacteriology. Until February 2018, the phylum Proteobacteria consisted of eight classes, 44 orders, 120 families, and more than 1,000 genera. Proteobacteria species isolated from various environments in Korea have been reported since 1999, and 644 species have been approved as of February 2018. In this study, all novel Proteobacteria species from Korean environments were affiliated with four classes, 25 orders, 65 families, and 261 genera. A total of 304 species belonged to the class Alphaproteobacteria, 257 species to the class Gammaproteobacteria, 82 species to the class Betaproteobacteria, and one species to the class Epsilonproteobacteria. The predominant orders were Rhodobacterales, Sphingomonadales, Burkholderiales, Lysobacterales and Alteromonadales. The most diverse and greatest number of novel Proteobacteria species were isolated from marine environments. Proteobacteria species were isolated from the whole territory of Korea, with especially large numbers from the regions of Chungnam/Daejeon, Gyeonggi/Seoul/Incheon, and Jeonnam/Gwangju. -

Abstract Tracing Hydrocarbon
ABSTRACT TRACING HYDROCARBON CONTAMINATION THROUGH HYPERALKALINE ENVIRONMENTS IN THE CALUMET REGION OF SOUTHEASTERN CHICAGO Kathryn Quesnell, MS Department of Geology and Environmental Geosciences Northern Illinois University, 2016 Melissa Lenczewski, Director The Calumet region of Southeastern Chicago was once known for industrialization, which left pollution as its legacy. Disposal of slag and other industrial wastes occurred in nearby wetlands in attempt to create areas suitable for future development. The waste creates an unpredictable, heterogeneous geology and a unique hyperalkaline environment. Upgradient to the field site is a former coking facility, where coke, creosote, and coal weather openly on the ground. Hydrocarbons weather into characteristic polycyclic aromatic hydrocarbons (PAHs), which can be used to create a fingerprint and correlate them to their original parent compound. This investigation identified PAHs present in the nearby surface and groundwaters through use of gas chromatography/mass spectrometry (GC/MS), as well as investigated the relationship between the alkaline environment and the organic contamination. PAH ratio analysis suggests that the organic contamination is not mobile in the groundwater, and instead originated from the air. 16S rDNA profiling suggests that some microbial communities are influenced more by pH, and some are influenced more by the hydrocarbon pollution. BIOLOG Ecoplates revealed that most communities have the ability to metabolize ring structures similar to the shape of PAHs. Analysis with bioinformatics using PICRUSt demonstrates that each community has microbes thought to be capable of hydrocarbon utilization. The field site, as well as nearby areas, are targets for habitat remediation and recreational development. In order for these remediation efforts to be successful, it is vital to understand the geochemistry, weathering, microbiology, and distribution of known contaminants. -
