A Report of 26 Unrecorded Bacterial Species in Korea, Isolated from Urban Streams of the Han River Watershed in 2018
Journal of Species Research 8(3):249-258, 2019 A report of 26 unrecorded bacterial species in Korea, isolated from urban streams of the Han River watershed in 2018 Yochan Joung§,1, Hye-Jin Jang§,1, Myeong Woon Kim§,2, Juchan Hwang1, Jaeho Song1 and Jang-Cheon Cho1,* 1Department of Biological Sciences, Inha University, Incheon 22212, Republic of Korea 2Department of Energy and Environmental Engineering, Daejin University, Hoguk-ro 1007, Pocheon-si, Gyeonggi-do 11159, Republic of Korea *Correspondent: [email protected] §These authors contributed equally to this work. Owing to a distinct environmental regime and anthropogenic effects, freshwater bacterial communities of urban streams are considered to be different from those of large freshwater lakes and rivers. To obtain unrecorded, freshwater bacterial species in Korea, water and sediment samples were collected from various urban streams of the Han River watershed in 2018. After plating the freshwater samples on R2A agar, approximately 1000 bacterial strains were isolated from the samples as single colonies and identified using 16S rRNA gene sequence analyses. A total of 26 strains, with >98.7% 16S rRNA gene sequence similarity with validly published bacterial species but not reported in Korea, were determined to be unrecorded bacterial species in Korea. The unrecorded bacterial strains were phylogenetically diverse and belonged to four phyla, six classes, 12 orders, 16 families, and 21 genera. At the generic level, the unreported species were assigned to Nocardioides, Streptomyces, Microbacterium, Kitasatospora, Herbiconiux, Corynebacterium, and Microbacterium of the class Actinobacteria; Paenibacillus and Bacillus of the class Bacilli; Caulobacter, Methylobacterium, Novosphingobium, and Porphyrobacter of the class Alphaproteobacteria; Aquabacterium, Comamonas, Hydrogenophaga, Laribacter, Rivicola, Polynucleobacter, and Vogesella of the class Betaproteobacteria; Arcobacter of the class Epsilonproteobacteria; and Flavobacterium of the class Flavobacteriia. -

Each strain showed the high sequence similarity (>99.1%) with the closest bacterial species, forming a robust phylogenetic clade. These strains have not been previously recorded in Korea. According to the recently updated taxonomy of the phylum Actinobacteria based upon 16S rRNA trees, we report 25 genera of 13 families within 5 orders of the class Actinobacteria as actinobacterial species found in Korea. -
Culturable Bacteria in the Hedera Helix Phylloplane Vincent Stevens1* , Sofie Thijs1 and Jaco Vangronsveld1,2*
Stevens et al. BMC Microbiology (2021) 21:66 https://doi.org/10.1186/s12866-021-02119-z RESEARCH ARTICLE Open Access Diversity and plant growth-promoting potential of (un)culturable bacteria in the Hedera helix phylloplane Vincent Stevens1* , Sofie Thijs1 and Jaco Vangronsveld1,2* Abstract Background: A diverse community of microbes naturally exists on the phylloplane, the surface of leaves. It is one of the most prevalent microbial habitats on earth and bacteria are the most abundant members, living in communities that are highly dynamic. Today, one of the key challenges for microbiologists is to develop strategies to culture the vast diversity of microorganisms that have been detected in metagenomic surveys. Results: We isolated bacteria from the phylloplane of Hedera helix (common ivy), a widespread evergreen, using five growth media: Luria–Bertani (LB), LB01, yeast extract–mannitol (YMA), yeast extract–flour (YFlour), and YEx. We also included a comparison with the uncultured phylloplane, which we showed to be dominated by Proteobacteria, Actinobacteria, Bacteroidetes, and Firmicutes. Inter-sample (beta) diversity shifted from LB and LB01 containing the highest amount of resources to YEx, YMA, and YFlour which are more selective. All growth media equally favoured Actinobacteria and Gammaproteobacteria, whereas Bacteroidetes could only be found on LB01, YEx, and YMA. LB and LB01 favoured Firmicutes and YFlour was most selective for Betaproteobacteria. At the genus level, LB favoured the growth of Bacillus and Stenotrophomonas, while YFlour was most selective for Burkholderia and Curtobacterium. The in vitro plant growth promotion (PGP) profile of 200 isolates obtained in this study indicates that previously uncultured bacteria from the phylloplane may have potential applications in phytoremediation and other plant-based biotechnologies. -

International Journal of Speleology, 41(2), 125-136 Tampa, FL (USA). ISSN 0392-6672. http://dx.doi.org/10.5038/1827-806X.41.2.1 The main objective of this work was the comparative analysis of a large number of bacterial strains isolated from biodeteriorated surfaces in three different sites, namely the catacombs of St. Callistus in Rome, Italy, the catacombs dedicated to St. Agatha in Ra- bat, Malta and the Cave of Bats in Zuheros, Spain. Our results showed that even considering only culturable chemoorganotrophic bacteria the variability is very high, reflecting the great variety of microhabitats present. Hence any strategies to prevent, control or eliminate the biofilm-embedded microbiota from an archeological surface should take into account a number of considerations as stipulated in our study.

Marine Rare Actinomycetes: a Promising Source of Structurally Diverse and Unique Novel Natural Products

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. -

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.
