  • Chapter 1.0: Introduction
    CHAPTER 1.0: INTRODUCTION 1.1 Why study Antarctica? The Antarctic includes some of the most extreme terrestrial environments by very low temperature, frequent freeze-thaw and wet-dry cycles, low and transient precipitation, reduced humidity, rapid drainage and limited organic nutrients which are considered as unfavorable condition (Yergeau et al., 2006). Located in the Earth‟s south hemisphere, Antarctica has received considerable amount of attention due to its untapped resources. Renowned for its cold, harsh conditions, there is an abundance of microbial life which has undergone their own adaption and evolutionary processes to survive. Since, Antarctic microbial habitats have remained relatively conserved for many years; there are unique opportunities for studying microbial evolution (Vincent, 2000). Besides that, presence of psychrophiles and other extermophiles in the environment are interesting specimens of nature‟s wonder. Psychrophilic enzymes produced have high potential in biotechnology for example the conservation of energy by reducing the need of heat treatment, the application of eurythermal polar cyanobacteria for wastewater treatment in cold climates (Tang et al., 1997) and the integration of proteases, lipases and cellulases into detergents to improve its mode of action in cold water. 1.2 Antarctic microorganisms Although bacterial researches have been conducted since early 1900s by Ekelof (Boyd and Boyd, 1962), little is known about the presence and characteristics of bacteria in the Antarctica. Microorganisms dominate Antarctic biology compare to other continent (Friedmann, 1993) as well as they are fundamental to the functioning of Antarctic ecosystems. Baseline knowledge of prokaryotic biodiversity in Antarctica is still limited (Bohannan 1 and Hughes, 2003). Among these microorganisms, bacteria are an important part of the soil.

  • Arthrobacter Paludis Sp. Nov., Isolated from a Marsh
    TAXONOMIC DESCRIPTION Zhang et al., Int J Syst Evol Microbiol 2018;68:47–51 DOI 10.1099/ijsem.0.002426 Arthrobacter paludis sp. nov., isolated from a marsh Qi Zhang,1 Mihee Oh,1 Jong-Hwa Kim,1 Rungravee Kanjanasuntree,1 Maytiya Konkit,1 Ampaitip Sukhoom,2 Duangporn Kantachote2 and Wonyong Kim1,* Abstract A novel Gram-stain-positive, strictly aerobic, non-endospore-forming bacterium, designated CAU 9143T, was isolated from a hydric soil sample collected from Seogmo Island in the Republic of Korea. Strain CAU 9143T grew optimally at 30 C, at pH 7.0 and in the presence of 1 % (w/v) NaCl. The phylogenetic trees based on 16S rRNA gene sequences revealed that strain CAU 9143T belonged to the genus Arthrobacter and was closely related to Arthrobacter ginkgonis SYP-A7299T (97.1 % T similarity). Strain CAU 9143 contained menaquinone MK-9 (H2) as the major respiratory quinone and diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, two glycolipids and two unidentified phospholipids as the major polar lipids. The whole-cell sugars were glucose and galactose. The peptidoglycan type was A4a (L-Lys–D-Glu2) and the major cellular fatty T acid was anteiso-C15 : 0. The DNA G+C content was 64.4 mol% and the level of DNA–DNA relatedness between CAU 9143 and the most closely related strain, A. ginkgonis SYP-A7299T, was 22.3 %. Based on phenotypic, chemotaxonomic and genetic data, strain CAU 9143T represents a novel species of the genus Arthrobacter, for which the name Arthrobacter paludis sp. nov. is proposed. The type strain is CAU 9143T (=KCTC 13958T,=CECT 8917T).

Since most of the actinobacteria cannot be cultivated, their antimicrobial potential awaits to be revealed. We hypothesized that the actinobacterial endophyte communities inside Melia toosendan (Chinaberry) tree are diverse, include strains with antimicrobial activity, and that antimicrobial activity can be detected using a cultivation independent approach and co-occurrence analysis. We isolated and identifed actinobacteria from Chinaberry, tested their antimicrobial activities, and characterized the communities using amplicon sequencing and denaturing gradient gel electrophoresis as cultivation independent methods. Most of the isolates were identifed as Streptomyces spp., whereas based on amplicon sequencing the most abundant OTU was assigned to Rhodococcus, and Tomitella was the most diverse genus. Out of the 135 isolates, 113 inhibited the growth of at least one indicator organism. Six out of the 7577 operational taxonomic units (OTUs) matched 46 cultivated isolates. Only three OTUs, Streptomyces OTU4, OTU11, and OTU26, and their corresponding isolate groups were available for comparing co-occurrences and antimicrobial activity. Streptomyces OTU4 correlated negatively with a high number of OTUs, and the isolates corresponding to Streptomyces OTU4 had high antimicrobial activity. However, for the other two OTUs and their corresponding isolate groups there was no clear relation between the numbers of negative correlations and antimicrobial activity.

However, the knowledge of culturable bacterial communities found in this extreme ecotope’s soil is yet insufficient. Therefore, our research has been aimed to fulfil this lack of knowledge and improve the understanding of functioning of edaphic bacterial communities of the Central Mojave Desert soil. We characterized aerobic heterotrophic soil bacterial communities of the central region of the Mojave Desert. A high total number of prokaryotic cells and a high proportion of culturable forms in the soil studied were observed. Prevalence of Actinobacteria, Proteobacteria, and Firmicutes was discovered. The dominance of pigmented strains in culturable communities and high proportion of thermotolerant and pH-tolerant bacteria were detected. Resistance to a number of salts, including the ones found in Martian regolith, as well as antibiotic resistance, were also estimated.

  • Taxonomy and Systematics of Plant Probiotic Bacteria in the Genomic Era

DOI: 10.3934/microbiol.2017.3.383 Received: 03 March 2017 Accepted: 22 May 2017 Published: 31 May 2017 http://www.aimspress.com/journal/microbiology Review Taxonomy and systematics of plant probiotic bacteria in the genomic era Lorena Carro * and Imen Nouioui School of Biology, Newcastle University, Newcastle upon Tyne, UK * Correspondence: Email: [email protected]. Abstract: Recent decades have predicted significant changes within our concept of plant endophytes, from only a small number specific microorganisms being able to colonize plant tissues, to whole communities that live and interact with their hosts and each other. Many of these microorganisms are responsible for health status of the plant, and have become known in recent years as plant probiotics. Contrary to human probiotics, they belong to many different phyla and have usually had each genus analysed independently, which has resulted in lack of a complete taxonomic analysis as a group. This review scrutinizes the plant probiotic concept, and the taxonomic status of plant probiotic bacteria, based on both traditional and more recent approaches. Phylogenomic studies and genes with implications in plant-beneficial effects are discussed. This report covers some representative probiotic bacteria of the phylum Proteobacteria, Actinobacteria, Firmicutes and Bacteroidetes, but also includes minor representatives and less studied groups within these phyla which have been identified as plant probiotics.
