ABSTRACT OF DISSERTATION Andres Enrique Nunez The Graduate School University of Kentucky 2008 MICROBIAL COMMUNITY STRUCTURE DYNAMICS IN OHIO RIVER SEDIMENTS DURING REDUCTIVE DECHLORINATION OF PCBS ABSTRACT OF DISSERTATION A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the College of Agriculture at the University of Kentucky By Andres Enrique Nunez Director: Dr. Elisa M. D’Angelo Lexington, KY 2008 Copyright © Andres Enrique Nunez 2008 ABSTRACT OF DISSERTATION MICROBIAL COMMUNITY STRUCTURE DYNAMICS IN OHIO RIVER SEDIMENTS DURING REDUCTIVE DECHLORINATION OF PCBS The entire stretch of the Ohio River is under fish consumption advisories due to contamination with polychlorinated biphenyls (PCBs). In this study, natural attenuation and biostimulation of PCBs and microbial communities responsible for PCB transformations were investigated in Ohio River sediments. Natural attenuation of PCBs was negligible in sediments, which was likely attributed to low temperature conditions during most of the year, as well as low amounts of available nitrogen, phosphorus, and organic carbon.

    1 Phylogenetic analysis reveals an ancient gene duplication as 2 the origin of the MdtABC efflux pump. 3 4 Kamil Górecki1, Megan M. McEvoy1,2,3 5 1Institute for Society & Genetics, 2Department of MicroBiology, Immunology & Molecular 6 Genetics, and 3Molecular Biology Institute, University of California, Los Angeles, CA 90095, 7 United States of America 8 Corresponding author: [email protected] (M.M.M.) 9 1 10 Abstract 11 The efflux pumps from the Resistance-Nodulation-Division family, RND, are main 12 contributors to intrinsic antibiotic resistance in Gram-negative bacteria. Among this family, the 13 MdtABC pump is unusual by having two inner membrane components. The two components, 14 MdtB and MdtC are homologs, therefore it is evident that the two components arose by gene 15 duplication. In this paper, we describe the results obtained from a phylogenetic analysis of the 16 MdtBC pumps in the context of other RNDs. We show that the individual inner membrane 17 components (MdtB and MdtC) are conserved throughout the Proteobacterial species and that their 18 existence is a result of a single gene duplication. We argue that this gene duplication was an ancient 19 event which occurred before the split of Proteobacteria into Alpha-, Beta- and Gamma- classes. 20 Moreover, we find that the MdtABC pumps and the MexMN pump from Pseudomonas aeruginosa 21 share a close common ancestor, suggesting the MexMN pump arose by another gene duplication 22 event of the original Mdt ancestor. Taken together, these results shed light on the evolution of the 23 RND efflux pumps and demonstrate the ancient origin of the Mdt pumps and suggest that the core 24 bacterial efflux pump repertoires have been generally stable throughout the course of evolution.

The sediment was incubated together with a mix- ture of four electron donors and pentaCB, and after five months of incubation, the microbial community structure was analyzed. Both DGGE and clone library analyses showed that the most expansive phylogenetic group within the consortium was affiliated with the phylum Chloroflexi, which includes Dehalococcoides-like bacteria. PCR using a degenerate primer set targeting conserved regions in reductive-dehalogenase-homologous (rdh) genes from Dehalococcoides species revealed that DNA fragments (approximately 1.5–1.7 kb) of rdh genes were am- plified from genomic DNA of the consortium. The deduced amino acid sequences of the rdh genes shared sever- al characteristics of reductive dehalogenases.

  • Full Paper Ilumatobacter Fluminis Gen. Nov., Sp. Nov., a Novel Actinobacterium Isolated from the Sediment of an Estuary
    J. Gen. Appl. Microbiol., 55, 201‒205 (2009) Full Paper Ilumatobacter fl uminis gen. nov., sp. nov., a novel actinobacterium isolated from the sediment of an estuary Atsuko Matsumoto,1 Hiroki Kasai,2 Yoshihide Matsuo,2 Satoshi Ōmura,1 Yoshikazu Shizuri,2 and Yōko Takahashi1,* 1 Kitasato Institute for Life Sciences, Kitasato University, Minato-ku, Tokyo 108‒8641, Japan 2 Marine Biotechnology Institute, Kitasato University, Kamaishi, Iwate 026‒0001, Japan (Received December 1, 2008; Accepted February 2, 2009) Bacterial strain YM22-133T was isolated from the sediment of an estuary and grew in media with an artifi cial seawater base. Strain YM22-133T was Gram-positive, aerobic, non-motile and rod shaped. The cell-wall peptidoglycan contained LL-DAP, glycine, alanine and hydroxyglutamate. The predominant menaquinone was MK-9 (H8), with MK-9 (H0), MK-9 (H2), MK-9 (H4) and MK-9 (H6) present as minor menaquinones. The G+C content of the genomic DNA from the strain was 68 mol%. Phylogenetic analysis of the 16S rRNA gene sequence showed that the strain is near- est to Acidimicrobium ferrooxidans DSM 10331T. However, the similarity is relatively low (87.1%) and the physiological characteristics are also different: Acidimicrobium ferrooxidans is thermo- tolerant and acidophilic. Therefore, strain YM22-133T can be classifi ed as a novel genus and species, Ilumatobacter fl uminis gen. nov., sp. nov. (type strain YM22-133T =DSM 18936T=MBIC 08263T). Key Words—Acidimicrobium; Actinobacteria; artifi cial sea water; Ilumatobacter fl uminis gen. nov., sp. nov. Introduction isolated as part of this study. Phylogenetic analysis on the basis of 16S rRNA gene sequence analysis showed Recently, bacteria isolated from marine environ- that the strain is most closely related to the genus Aci- ments have attracted attention due to the recognition dimicrobium (Clark and Norris, 1996).
