This organism grew optimally at 9 to 12°C and did not grow at higher than 18°C. Chemotaxonomic characteristics of this organism were the presence of 2,4-diaminobutyricacid in the cell wall and menaquinone-10as the predominant respiratory quinone. The cellular fatty acid profile, which contained a significant amount of an anteiso-branched monounsaturated acid, 12-methyl tetradecenoic acid, was a distinctive characteristic of this organism and was reasonable for adaptation to low temperature. Phylogenetic analysis based on 16s ribosomal DNA sequences revealed that this organism was positioned at a separate branch in the family Microbacteriaceae, actinomycetes with group B peptidoglycan. We propose the name Cryobacterium psychrophilum gen. nov., sp. nov. for this organism. The type strain is JCM 1463 (=IAM 12024 =ATCC 43563 =IF0 15735 =NCIMB 2068). In the course of an ecological study of microorganisms in albidurn JCM 1344T, Curtobacterium citreum JCM 134fiT, and Curtobacterium Antarctica, Inoue isolated some obligately psychrophilic bac- pusillurn JCM 1350T were cultivated at 10 and 17°C on R agar for comparison of the cellular fatty acid compositions.

ABSTRACT Computational approaches are often used to predict regulatory RNAs in bacteria, but their success is limited to RNAs that are highly conserved across phyla, in sequence and structure. The ANTAR regulatory system consists of a family of RNAs (the ANTAR-target RNAs) that selectively recruit ANTAR proteins. This protein-RNA complex together regulates genes at the level of translation or transcriptional elongation.

    J. Gen. Appl. Microbiol., 54, 253‒258 (2008) Full Paper Schumannella luteola gen. nov., sp. nov., a novel genus of the family Microbacteriaceae Sun-Young An*, Tian Xiao, and Akira Yokota Institute of Molecular and Cellular Biosciences, The University of Tokyo, Bunkyo-ku, Tokyo 113‒0032, Japan (Received February 28, 2008; Accepted June 24, 2008) An actinobacterial strain KHIAT, isolated from lichen in Tokyo, was taxonomically characterized using a polyphasic approach. The isolate is a Gram-positive, anaerobic, non-motile and rod- shaped bacterium. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the isolate is represented as an independent lineage distinctive from the Microbacteriaceae genera. The G+C content of DNA was 58.7 mol%. The chemotaxonomic characteristics of the isolate are cell wall peptidoglycan type (2,4-diaminobutyric acid), major cellular fatty acids (anteiso-C15:0 and iso-C16:0) and quinone type (MK-11 and MK-10). On the basis of the phenotypic and phyloge- netic distinctness, it is proposed that strain KHIAT represents a novel species in a new genus of the family Microbacteriaceae, Schumannella luteola gen. nov., sp. nov. The type strain is KHIAT (=JCM 23215T=TISTR 1824T). Key Words—Schumannella luteola gen. nov., sp. nov. Introduction butyric acid in the cell wall.

  • Actinobacterial Diversity in Atacama Desert Habitats As a Road Map to Biodiscovery
    Actinobacterial Diversity in Atacama Desert Habitats as a Road Map to Biodiscovery A thesis submitted by Hamidah Idris for the award of Doctor of Philosophy July 2016 School of Biology, Faculty of Science, Agriculture and Engineering, Newcastle University, Newcastle Upon Tyne, United Kingdom Abstract The Atacama Desert of Northern Chile, the oldest and driest nonpolar desert on the planet, is known to harbour previously undiscovered actinobacterial taxa with the capacity to synthesize novel natural products. In the present study, culture-dependent and culture- independent methods were used to further our understanding of the extent of actinobacterial diversity in Atacama Desert habitats. The culture-dependent studies focused on the selective isolation, screening and dereplication of actinobacteria from high altitude soils from Cerro Chajnantor. Several strains, notably isolates designated H9 and H45, were found to produce new specialized metabolites. Isolate H45 synthesized six novel metabolites, lentzeosides A-F, some of which inhibited HIV-1 integrase activity. Polyphasic taxonomic studies on isolates H45 and H9 showed that they represented new species of the genera Lentzea and Streptomyces, respectively; it is proposed that these strains be designated as Lentzea chajnantorensis sp. nov. and Streptomyces aridus sp. nov.. Additional isolates from sampling sites on Cerro Chajnantor were considered to be nuclei of novel species of Actinomadura, Amycolatopsis, Cryptosporangium and Pseudonocardia. A majority of the isolates produced bioactive compounds that inhibited the growth of one or more strains from a panel of six wild type microorganisms while those screened against Bacillus subtilis reporter strains inhibited sporulation and cell envelope, cell wall, DNA and fatty acid synthesis.

  • Cold-Loving Bacteria from Antarctic and Arctic : Occurrence, Survival and Usefulness
    COLD-LOVING BACTERIA FROM ANTARCTIC AND ARCTIC : OCCURRENCE, SURVIVAL AND USEFULNESS Dr S Shivaji CCMB, Hyderabad March, 2012 Extremophiles Deep sea vent Sea ice Thermophiles Cold loving microbes (psychrophiles) Soda lake Alkali-loving microbes (Alkaliphiles) Acid-loving microbes Natronobacterium (Acidophiles) gregoryi Haloferax volcanii Sulfolobus acidocaldarius Salt-loving microbes (Halophiles) Salt lake THERMOPHILES Yellowstone hot spring Pyrococcus furiosis In the 1960s biologists thought life would not tolerate temperatures anywhere near 80°C. But Thomas Brock found Thermus aquaticus that could live and reproduce near 100°C the temperature of boiling water. HOW HOT IS HOT? Pyrococcus furiosis was isolated from a geothermal sediment in Vulcano Island, Italy. Grows between 100-113°C with an optimum at 100°C. It has a generation time of 35 minutes. Produces enzymes which are extremely thermostable. It is the preferred source for Pfu DNA polymerase for PCR. HOW COLD IS COLD?
