Acetic acid bacteria belonging to the new genus Asaia and the genera Gluconobacter, Gluconacetobacter, Acetobacter and Acidomonas of the alpha ─ 1 sub- group ubiquitously contained spermidine as the major polyamine. Aerobic bacteriochlorophyll a ─ containing Acidisphaera, Craurococcus and Paracraurococcus(alpha ─ 1)and Roseibium (alpha-2)contained spermidine and lacked homospermidine. New Rhizobium species, including some species transferred from the genera Agrobacterium and Allorhizobium, and new Sinorhizobium and Mesorhizobium species of the alpha ─ 2 subgroup contained homospermidine as a major polyamine. Homospermidine was the major polyamine in the genera Oligotropha, Carbophilus, Zavarzinia, Blastobacter, Starkeya and Rhodoblastus of the alpha ─ 2 subgroup. Rhodobaca bogoriensis of the alpha ─ 3 subgroup contained spermidine. Within the alpha ─ 4 sub- group, the genus Sphingomonas has been divided into four clusters, and species of the emended Sphingomonas(cluster I)contained homospermidine whereas those of the three newly described genera Sphingobium, Novosphingobium and Sphingopyxis(corresponding to clusters II, III and IV of the former Sphingomonas)ubiquitously contained spermidine. -

The Eastern Nebraska Salt Marsh Microbiome Is Well Adapted to an Alkaline and Extreme Saline Environment
life Article The Eastern Nebraska Salt Marsh Microbiome Is Well Adapted to an Alkaline and Extreme Saline Environment Sierra R. Athen, Shivangi Dubey and John A. Kyndt * College of Science and Technology, Bellevue University, Bellevue, NE 68005, USA; [email protected] (S.R.A.); [email protected] (S.D.) * Correspondence: [email protected] Abstract: The Eastern Nebraska Salt Marshes contain a unique, alkaline, and saline wetland area that is a remnant of prehistoric oceans that once covered this area. The microbial composition of these salt marshes, identified by metagenomic sequencing, appears to be different from well-studied coastal salt marshes as it contains bacterial genera that have only been found in cold-adapted, alkaline, saline environments. For example, Rubribacterium was only isolated before from an Eastern Siberian soda lake, but appears to be one of the most abundant bacteria present at the time of sampling of the Eastern Nebraska Salt Marshes. Further enrichment, followed by genome sequencing and metagenomic binning, revealed the presence of several halophilic, alkalophilic bacteria that play important roles in sulfur and carbon cycling, as well as in nitrogen fixation within this ecosystem. Photosynthetic sulfur bacteria, belonging to Prosthecochloris and Marichromatium, and chemotrophic sulfur bacteria of the genera Sulfurimonas, Arcobacter, and Thiomicrospira produce valuable oxidized sulfur compounds for algal and plant growth, while alkaliphilic, sulfur-reducing bacteria belonging to Sulfurospirillum help balance the sulfur cycle. This metagenome-based study provides a baseline to understand the complex, but balanced, syntrophic microbial interactions that occur in this unique Citation: Athen, S.R.; Dubey, S.; inland salt marsh environment. -

Gura A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE December 2019 Committee: Scott O. Rogers, Advisor Helen Michaels Paul Morris © 2019 Colby Gura All Rights Reserved iii ABSTRACT Scott O. Rogers, Advisor Chapter 1: Lake Vostok is named for the nearby Vostok Station located at 78°28’S, 106°48’E and at an elevation of 3,488 m. The lake is covered by a glacier that is approximately 4 km thick and comprised of 4 different types of ice: meteoric, basal, type 1 accretion ice, and type 2 accretion ice. Six samples were derived from the glacial, basal, and accretion ice of the 5G ice core (depths of 2,149 m; 3,501 m; 3,520 m; 3,540 m; 3,569 m; and 3,585 m) and prepared through several processes. The RNA and DNA were extracted from ultracentrifugally concentrated meltwater samples. From the extracted RNA, cDNA was synthesized so the samples could be further manipulated. Both the cDNA and the DNA were amplified through polymerase chain reaction. Ion Torrent primers were attached to the DNA and cDNA and then prepared to be sequenced. Following sequencing the sequences were analyzed using BLAST. Python and Biopython were then used to collect more data and organize the data for manual curation and analysis. Chapter 2: As a result of the glacier and its geographic location, Lake Vostok is an extreme and unique environment that is often compared to Jupiter’s ice-covered moon, Europa. -

Anil Kumar Microbial Type Culture Collection and Gene bank Institute of Microbial Technology, Sector 39A, Chandigarh - 160 036, INDIA Email: [email protected] Phone: +91-172-6665170 1 Abstract A novel marine, Gram-negative, rod-shaped bacterium, designated strain N9T, was isolated from a water sample of the sea shore at Visakhapatnam, Andhra Pradesh (India). Strain N9T was found to be positive for oxidase and catalase activities. The fatty acids were found to be dominated by C16:0, C18:1 ω7c and summed in feature 3 (C16:1 ω7c and/or C16:1 ω6c). Strain N9T was determined to contain Q-10 as the major respiratory quinone and phosphatidylethanolamine, phosphatidylglycerol, two aminophospholipids, two phospholipids and four unidentified lipids as polar lipids. The DNA G+C content of the strain N9T was found to be 63 mol%. 16S rRNA gene sequence analysis indicated that Rhodobacter sphaeroides, Rhodobacter johrii, Pseudorhodobacter ferrugineus, Rhodobacter azotoformans, Rhodobacter ovatus and Pseudorhodobacter aquimaris were the nearest phylogenetic neighbours, with pair-wise sequence similarities of 95.43, 95.36, 94.24, 95.31, 95.60 and 94.74 % respectively. -
Horizontal Operon Transfer, Plasmids, and the Evolution of Photosynthesis in Rhodobacteraceae

This article is published with open access Abstract The capacity for anoxygenic photosynthesis is scattered throughout the phylogeny of the Proteobacteria. Their photosynthesis genes are typically located in a so-called photosynthesis gene cluster (PGC). It is unclear (i) whether phototrophy is an ancestral trait that was frequently lost or (ii) whether it was acquired later by horizontal gene transfer. We investigated the evolution of phototrophy in 105 genome-sequenced Rhodobacteraceae and provide the first unequivocal evidence for the horizontal transfer of the PGC. The 33 concatenated core genes of the PGC formed a robust phylogenetic tree and the comparison with single-gene trees demonstrated the dominance of joint evolution. The PGC tree is, however, largely incongruent with the species tree and at least seven transfers of the PGC are required to reconcile both phylogenies. 1234567890();,: 1234567890();,: The origin of a derived branch containing the PGC of the model organism Rhodobacter capsulatus correlates with a diagnostic gene replacement of pufC by pufX. The PGC is located on plasmids in six of the analyzed genomes and its DnaA- like replication module was discovered at a conserved central position of the PGC. A scenario of plasmid-borne horizontal transfer of the PGC and its reintegration into the chromosome could explain the current distribution of phototrophy in Rhodobacteraceae. -

Significant increases were observed in dibromomethane concentrations and bacterial 16S rRNA gene copy numbers in the treated substrates incubated for 13 d. The accumulated bacterial community was investigated by denaturing gradient gel electrophoresis and amplicon analyses. The dominant genotypes corresponded to the genera Roseobacter, Lentibacter, and Amylibacter; the family Flavobacteriaceae; and the phylum Planctomycetes, including methylotrophs of the genus Methylophaga and the family Methylophilaceae. Therefore, various phylotypes responded along with the dehalogenation processes in subarctic seawater.
