Pieper, Ramón Rosselló-Móra, Jesús Sánchez, Jana Seifert and Manuel Ferrer 10 Supporting Online Material includes Text (Supporting Materials and Methods) Tables S1 to S9 Figures S1 to S7 1 SUPPORTING TEXT Supporting Materials and Methods Soil characterisation Soil pH was measured in a suspension of soil and water (1:2.5) with a glass electrode, and 5 electrical conductivity was measured in the same extract (diluted 1:5). Primary soil characteristics were determined using standard techniques, such as dichromate oxidation (organic matter content), the Kjeldahl method (nitrogen content), the Olsen method (phosphorus content) and a Bernard calcimeter (carbonate content). The Bouyoucos Densimetry method was used to establish textural data. Exchangeable cations (Ca, Mg, K and 10 Na) extracted with 1 M NH 4Cl and exchangeable aluminium extracted with 1 M KCl were determined using atomic absorption/emission spectrophotometry with an AA200 PerkinElmer analyser. The effective cation exchange capacity (ECEC) was calculated as the sum of the values of the last two measurements (sum of the exchangeable cations and the exchangeable Al). Analyses were performed immediately after sampling. 15 Hydrocarbon analysis Extraction (5 g of sample N and Nbs) was performed with dichloromethane:acetone (1:1) using a Soxtherm extraction apparatus (Gerhardt GmbH & Co. -
Comparative Genomic Analysis of Three Pseudomonas

One ecosystem service that has garnered recent attention is the ability of oysters to sequester impurities and nutrients, such as nitrogen (N), from the estuarine water that feeds them, via their exceptional filtration mechanism coupled with microbially-mediated denitrification processes. It is the oyster-associated microbiomes that essentially provide these myriads of ecological functions, yet not much is known on these microbiota at the genomic scale, especially from warm temperate and tropical water habitats. Among the suite of bacterial genera that appear to interplay with the oyster host species, pseudomonads deserve further assessment because Citation: Pathak, A.; Stothard, P.; of their immense metabolic and ecological potential. To obtain a comprehensive understanding on Chauhan, A.

DE LEY' Laboratorium voor Microbiologie en Microbiele Genetica, Rijksuniversiteit, B-9000 Ghent, Belgium, and Culture Collection, Department of Clinical Bacteriology, University of Goteborg, S-413 46 Goteborg, Sweden2 We used DNA-rRNA hybridization, DNA base composition, polyacrylamide gel electrophoresis of whole-cell proteins, DNA-DNA hybridization, numerical analysis of phenotypic features, and immunotyping to study the taxonomy of the genus Comamonas. The relationships of this genus to Aquaspirillum aquaticum and a group of clinical isolates (E. Falsen group 10 [EF lo]) were studied. Our DNA and rRNA hybridization results indicate that the genus Comamonas consists of at least the following five genotypic groups: (i) Comamonas acidovoruns, (ii) Comamonas fesfosferoni,(iii) Comamonas ferrigena, (iv) A. aquaticum and a number of EF 10 strains, and (v) other EF 10 strains, several unnamed clinical isolates, and some misnamed strains of Pseudomonas alcaligenes and Pseudomonas pseudoalcaligenes subsp. pseudoalcaligenes. The existence of these five groups was confirmed by the results of immunotyping and protein gel electrophoresis. A numerical analysis of morpho- logical, auxanographic, and biochemical data for the same organisms revealed the existence of three large phena. Two of these phena (C. acidovorans and C. tesfosferoni)correspond to two of the genotypic groups. -

Fax: j31 317 483829. e-mail: Arthur.Wolterink!algemeen.micr.wag-ur.nl A Gram-negative, facultatively anaerobic, rod-shaped, dissimilatory chlorate- reducing bacterium, strain AW-1T, was isolated from biomass of an anaerobic chlorate-reducing bioreactor. Phylogenetic analysis of the 16S rDNA sequence showed 100% sequence similarity to Pseudomonas stutzeri DSM 50227 and 986% sequence similarity to the type strain of P. stutzeri (DSM 5190T). The species P. stutzeri possesses a high degree of genotypic and phenotypic heterogeneity. Therefore, eight genomic groups, termed genomovars, have been proposed based upon ∆Tm values, which were used to evaluate the quality of the pairing within heteroduplexes formed by DNA–DNA hybridization. In this study, DNA–DNA hybridization between strain AW-1T and P. stutzeri strains DSM 50227 and DSM 5190T revealed respectively 805 and 565% similarity. DNA–DNA hybridization between P. stutzeri strains DSM 50227 and DSM 5190T revealed 484% similarity. DNA–DNA hybridization indicated that strain AW-1T is not related at the species level to the type strain of P. stutzeri. However, strain AW-1T and P. stutzeri DSM 50227 are related at the species level. The physiological and biochemical properties of strain AW-1T and the two P. -

Marine rare actinomycetes represent a rather untapped source of chemically diverse secondary metabolites and novel bioactive compounds. In this review, we aim to summarize the present knowledge on the isolation, diversity, distribution and natural product discovery of marine rare actinomycetes reported from mid-2013 to 2017. A total of 97 new species, representing 9 novel genera and belonging to 27 families of marine rare actinomycetes have been reported, with the highest numbers of novel isolates from the families Pseudonocardiaceae, Demequinaceae, Micromonosporaceae and Nocardioidaceae. Additionally, this study reviewed 167 new bioactive compounds produced by 58 different rare actinomycete species representing 24 genera. Most of the compounds produced by the marine rare actinomycetes present antibacterial, antifungal, antiparasitic, anticancer or antimalarial activities. The highest numbers of natural products were derived from the genera Nocardiopsis, Micromonospora, Salinispora and Pseudonocardia. Members of the genus Micromonospora were revealed to be the richest source of chemically diverse and unique bioactive natural products. -

Extreme Environments and High-Level Bacterial Tellurite Resistance
microorganisms Review Extreme Environments and High-Level Bacterial Tellurite Resistance Chris Maltman 1,* and Vladimir Yurkov 2 1 Department of Biology, Slippery Rock University, Slippery Rock, PA 16001, USA 2 Department of Microbiology, University of Manitoba, Winnipeg, MB R3T 2N2, Canada; [email protected] * Correspondence: [email protected]; Tel.: +724-738-4963 Received: 28 October 2019; Accepted: 20 November 2019; Published: 22 November 2019 Abstract: Bacteria have long been known to possess resistance to the highly toxic oxyanion tellurite, most commonly though reduction to elemental tellurium. However, the majority of research has focused on the impact of this compound on microbes, namely E. coli, which have a very low level of resistance. Very little has been done regarding bacteria on the other end of the spectrum, with three to four orders of magnitude greater resistance than E. coli. With more focus on ecologically-friendly methods of pollutant removal, the use of bacteria for tellurite remediation, and possibly recovery, further highlights the importance of better understanding the effect on microbes, and approaches for resistance/reduction. The goal of this review is to compile current research on bacterial tellurite resistance, with a focus on high-level resistance by bacteria inhabiting extreme environments. Keywords: tellurite; tellurite resistance; extreme environments; metalloids; bioremediation; biometallurgy 1. Introduction Microorganisms possess a wide range of extraordinary abilities, from the production of bioactive molecules [1] to resistance to and transformation of highly toxic compounds [2–5]. Of great interest are bacteria which can convert the deleterious oxyanion tellurite to elemental tellurium (Te) through reduction. Currently, research into bacterial interactions with tellurite has been lagging behind investigation of the oxyanions of other metals such as nickel (Ni), molybdenum (Mo), tungsten (W), iron (Fe), and cobalt (Co).
