Despite their ecological importance, we have 17 limited understanding of how microbial communities vary across boreal moss species and the extent to 18 which local environmental conditions may influence the composition of these bacterial communities. 19 We used marker gene sequencing to analyze bacterial communities associated with eight boreal moss 20 species collected near Fairbanks, AK USA. We found that host identity was more important than site in 21 determining bacterial community composition and that mosses harbor diverse lineages of potential N2- 22 fixers as well as an abundance of novel taxa assigned to understudied bacterial phyla (including 23 candidate phylum WPS-2). -
Rhodoglobus Vestalii Gen. Nov., Sp. Nov., a Novel Psychrophilic Organism Isolated from an Antarctic Dry Valley Lake
International Journal of Systematic and Evolutionary Microbiology (2003), 53, 985–994 DOI 10.1099/ijs.0.02415-0 Rhodoglobus vestalii gen. nov., sp. nov., a novel psychrophilic organism isolated from an Antarctic Dry Valley lake Peter P. Sheridan,1 Jennifer Loveland-Curtze,2 Vanya I. Miteva2 and Jean E. Brenchley2 Correspondence 1Department of Biological Sciences, PO Box 8007, Idaho State University, Pocatello, Vanya I. Miteva ID 83209, USA [email protected] 2Department of Biochemistry and Molecular Biology, Pennsylvania State University, University Park, PA 16802, USA A novel, psychrophilic, Gram-positive bacterium (designated strain LV3T) from a lake near the McMurdo Ice Shelf, Antarctica, has been isolated and characterized. This organism formed red-pigmented colonies, had an optimal growth temperature of 18 ˚C and grew on a variety of media between ”2 and 21 ˚C. Scanning electron micrographs of strain LV3T that showed small rods with unusual bulbous protuberances during all phases of growth were of particular interest. The G+C content of the genomic DNA was approximately 62 mol%. The cell walls contained ornithine as the diamino acid. The major fatty acids were anteiso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0. Cells grown at ”2 ˚C contained significant amounts of anteiso-C15 : 1. The major menaquinones found in strain LV3T were MK-11 and MK-12. Phylogenetic analysis of the 16S rRNA gene sequence indicated that strain LV3T was a member of the family Microbacteriaceae and related to, but distinct from, organisms belonging to the genera Agreia, Leifsonia and Subtercola.In addition, alignments of 16S rRNA sequences showed that the sequence of strain LV3T contained a 13 bp insertion that was found in only a few related sequences. -

However, the knowledge of culturable bacterial communities found in this extreme ecotope’s soil is yet insufficient. Therefore, our research has been aimed to fulfil this lack of knowledge and improve the understanding of functioning of edaphic bacterial communities of the Central Mojave Desert soil. We characterized aerobic heterotrophic soil bacterial communities of the central region of the Mojave Desert. A high total number of prokaryotic cells and a high proportion of culturable forms in the soil studied were observed. Prevalence of Actinobacteria, Proteobacteria, and Firmicutes was discovered. The dominance of pigmented strains in culturable communities and high proportion of thermotolerant and pH-tolerant bacteria were detected. Resistance to a number of salts, including the ones found in Martian regolith, as well as antibiotic resistance, were also estimated. -
Taxonomy and Systematics of Plant Probiotic Bacteria in the Genomic Era
AIMS Microbiology, 3(3): 383-412. DOI: 10.3934/microbiol.2017.3.383 Received: 03 March 2017 Accepted: 22 May 2017 Published: 31 May 2017 http://www.aimspress.com/journal/microbiology Review Taxonomy and systematics of plant probiotic bacteria in the genomic era Lorena Carro * and Imen Nouioui School of Biology, Newcastle University, Newcastle upon Tyne, UK * Correspondence: Email: [email protected]. Abstract: Recent decades have predicted significant changes within our concept of plant endophytes, from only a small number specific microorganisms being able to colonize plant tissues, to whole communities that live and interact with their hosts and each other. Many of these microorganisms are responsible for health status of the plant, and have become known in recent years as plant probiotics. Contrary to human probiotics, they belong to many different phyla and have usually had each genus analysed independently, which has resulted in lack of a complete taxonomic analysis as a group. This review scrutinizes the plant probiotic concept, and the taxonomic status of plant probiotic bacteria, based on both traditional and more recent approaches. Phylogenomic studies and genes with implications in plant-beneficial effects are discussed. This report covers some representative probiotic bacteria of the phylum Proteobacteria, Actinobacteria, Firmicutes and Bacteroidetes, but also includes minor representatives and less studied groups within these phyla which have been identified as plant probiotics.

KALAKOUTSKII All-Russian Collection of Microorganisms, Institute of Biochemistry and Physiology of Microorganisms, Russian Academy of Sciences, Pushchino, Moscow Region, 142292, Russia A new genus, Ruthuyibucter, is proposed to accommodate three species of gram-positive, aerobic, coryneform bacteria previously placed in the genus Clavibucter (Ruthuyibucter ruthuyi comb. nov., Ruthuyibucter tritici comb. nov., and Ruthuyibucter irunicus comb. nov.), as well as six strains that were isolated from annual cereal grasses, may be responsible for ryegrass toxicity, and are very similar to the recently described organism Chvibacter toxicus sp. nov. (I. T. Riley and K. M. Ophel, Int. J. Syst. Bacteriol. 42:64-68, 1992). The properties of members of the genus Ruthuyibacter include coryneform morphology, peptidoglycan based on 2,4-diaminobutyric acid (type B2y), predominant menaquinones of the MK-10 type, and phosphatidylglycerol and diphosphatidylglycerol as basic polar lipids. The DNA base compositions range from 63 to 72 mol% G+C. The members of the new genus form a phenetic cluster distinct from Clavibucter spp. at a level -

PHA-producing microbes are therefore in great demand and a plethora of different environments, especially extreme habitats, have been probed for the presence of PHA-accumulators. However, the polar region has been neglected in this regard, probably due to the low accessibility of the sampling material and unusual cultivation regime. Here, we present the results of a screening procedure involving 200 bacterial strains isolated from 25 habitats of both polar regions. Agar-based tests, microscopy, and genetic methods were conducted to elucidate the biodiversity and potential of polar-region PHA-accumulators. -
