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). -

The phylum Acidobacteria is one of the most prevalent 15 and ecologically successful lineages on earth yet, currently, multiple lineages within this phylum 16 remain unexplored. Here, we utilize genomes recovered from Zodletone spring, an anaerobic 17 sulfide and sulfur-rich spring in southwestern Oklahoma, as well as from multiple disparate soil 18 and non-soil habitats, to examine the metabolic capabilities and ecological role of members of 19 the family UBA6911 (group18) Acidobacteria. -

Tree-Aggregated Predictive Modeling of Microbiome Data
www.nature.com/scientificreports OPEN Tree‑aggregated predictive modeling of microbiome data Jacob Bien1, Xiaohan Yan2, Léo Simpson3,4 & Christian L. Müller4,5,6* Modern high‑throughput sequencing technologies provide low‑cost microbiome survey data across all habitats of life at unprecedented scale. At the most granular level, the primary data consist of sparse counts of amplicon sequence variants or operational taxonomic units that are associated with taxonomic and phylogenetic group information. In this contribution, we leverage the hierarchical structure of amplicon data and propose a data‑driven and scalable tree‑guided aggregation framework to associate microbial subcompositions with response variables of interest. The excess number of zero or low count measurements at the read level forces traditional microbiome data analysis workfows to remove rare sequencing variants or group them by a fxed taxonomic rank, such as genus or phylum, or by phylogenetic similarity. By contrast, our framework, which we call trac (tree‑aggregation of compositional data), learns data‑adaptive taxon aggregation levels for predictive modeling, greatly reducing the need for user‑defned aggregation in preprocessing while simultaneously integrating seamlessly into the compositional data analysis framework. We illustrate the versatility of our framework in the context of large‑scale regression problems in human gut, soil, and marine microbial ecosystems. We posit that the inferred aggregation levels provide highly interpretable taxon groupings that can help microbiome researchers gain insights into the structure and functioning of the underlying ecosystem of interest. Microbial communities populate all major environments on earth and signifcantly contribute to the total plan- etary biomass. Current estimates suggest that a typical human-associated microbiome consists of ∼ 1013 bacteria1 and that marine bacteria and protists contribute to as much as 70% of the total marine biomass2. -

Ward1, Chloé-Rose Colombero1, David T. Johnston1 3 4 1Department of Earth and Planetary Science, Harvard University, Cambridge, MA 02138 5 *Correspondence to KMS: [email protected] 6 7 Abstract 8 The ability of aerobic microorganisms to regulate internal and external concentrations of the 9 reactive oxygen species (ROS) superoxide directly influences the health and viability of cells. 10 Superoxide dismutases (SODs) are the primary regulatory enzymes that are used by 11 microorganisms to degrade superoxide. SOD is not one, but three separate, non-homologous 12 enzymes that perform the same function. Thus, the evolutionary history of genes encoding for 13 different SOD enzymes is one of convergent evolution, which reflects environmental selection 14 brought about by an oxygenated atmosphere, changes in metal availability, and opportunistic 15 horizontal gene transfer (HGT). In this study we examine the phylogenetic history of the protein 16 sequence encoding for the nickel-binding metalloform of the SOD enzyme (SodN). A comparison 17 of organismal and SodN protein phylogenetic trees reveals several instances of HGT, including 18 multiple inter-domain transfers of the sodN gene from the bacterial domain to the archaeal domain. -

Pyrosequencing Investigation Into the Bacterial Community in Permafrost Soils Along the China-Russia Crude Oil Pipeline (CRCOP)
Pyrosequencing Investigation into the Bacterial Community in Permafrost Soils along the China-Russia Crude Oil Pipeline (CRCOP) Sizhong Yang1*, Xi Wen2, Huijun Jin1, Qingbai Wu1 1 State Key Laboratory of Frozen Soil Engineering (SKLFSE), Cold and Arid Regions Environmental and Engineering Research Institute (CAREERI), Chinese Academy of Sciences, Lanzhou, China, 2 College of Electrical Engineering, Northwest University for Nationalities, Lanzhou, China Abstract The China-Russia Crude Oil Pipeline (CRCOP) goes through 441 km permafrost soils in northeastern China. The bioremediation in case of oil spills is a major concern. So far, little is known about the indigenous bacteria inhabiting in the permafrost soils along the pipeline. A pilot 454 pyrosequencing analysis on the communities from four selected sites which possess high environment risk along the CRCOP is herein presented. The results reveal an immense bacterial diversity than previously anticipated. A total of 14448 OTUs with 84834 reads are identified, which could be assigned into 39 different phyla, and 223 families or 386 genera. Only five phyla sustain a mean OTU abundance more than 5% in all the samples, but they altogether account for 85.08% of total reads. Proteobacteria accounts for 41.65% of the total OTUs or 45% of the reads across all samples, and its proportion generally increases with soil depth, but OTUs numerically decline. Among Proteobacteria, the abundance of Beta-, Alpha-, Delta- and Gamma- subdivisions average to 38.7% (2331 OTUs), 37.5% (2257 OTUs), 10.35% (616 OTUs), and 6.21% (374 OTUs), respectively.

The microbial community drives important nutrient cycling processes that can influence soil quality, cropping productivity and environmental sustainability. In this research, a long-term agricultural experiment in a subtropical Acrisol was studied in south Brazil. The plots at this site represent two tillage systems, two nitrogen fertilization regimes and three crop rotation systems. Using Illumina high-throughput sequencing of the 16S rRNA gene, the archaeal and bacterial composition was determined from phylum to species level in the different plot treatments. -

Huber Collection of Microorganisms and Cell Cultures, Braunschweig, Germany [email protected] 2Department of Biology I, Biozentrum Ludwig Maximilian University of Munich, Planegg- Martinsried, Germany 3Technical University Braunschweig, Braunschweig, Germany Members of the phylum Acidobacteria are abundant in a wide variety of soil environments. Despite this, previous cultivation attempts have frequently failed to retrieve representative phylotypes of Acidobacteria, which have, therefore, been discovered by culture-independent methods (13175 acidobacterial sequences in the SILVA database version 123; NR99) and only 47 species have been described so far. Strain Ac_5_C6T represents the first isolate of the globally widespread and abundant subdivision 6 Acidobacteria and is described in the present study. Cells of strain Ac_5_C6T were Gram-stain-negative, immotile rods that divided by binary fission. They formed yellow, extremely cohesive colonies and stable aggregates even in rapidly shaken liquid cultures. Ac_5_C6T was tolerant of a wide range of temperatures (12–40 C) and pH values (4.7–9.0). It grew chemoorganoheterotrophically on a broad range of substrates including different sugars, organic acids, nucleic acids and complex proteinaceous compounds. T The major fatty acids of Ac_5_C6 were iso-C17 : 1 !9c,C18 : 1 !7c and iso-C15 : 0.
