  • 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).

Fairbanks, Alaska h r A Q t ■ ^% 0 /v AlA s ((0 August 2007 ^>c0^b Abstract Seafood quality can be assessed by determining the bacterial load and flora composition, although classical taxonomic methods are time-consuming and subjective to interpretation bias. A two-prong approach was used to assess a commercially available microbial identification system: confirmation of known cultures and fish spoilage experiments to isolate unknowns for identification. Bacterial isolates from the Fishery Industrial Technology Center Culture Collection (FITCCC) and the American Type Culture Collection (ATCC) were used to test the identification ability of the Sherlock Microbial Identification System (MIS). Twelve ATCC and 21 FITCCC strains were identified to species with the exception of Pseudomonas fluorescens and P. putida which could not be distinguished by cellular fatty acid analysis. The bacterial flora changes that occurred in iced Alaska pink salmon ( Oncorhynchus gorbuscha) were determined by the rapid method.

The qualified presumption of safety (QPS) assessment was developed to provide a harmonised generic pre-assessment to support safety risk assessments performed by EFSA’s Scientific Panels. The safety of unambiguously defined biological agents (at the highest taxonomic unit appropriate for the purpose for which an application is intended) and the completeness of the body of knowledge were assessed. Safety concerns identified for a taxonomic unit are, where possible and reasonable in number, reflected as ‘qualifications’ in connection with a recommendation for a QPS status. A total of 57 biological agents were notified to EFSA between the end of April 2016 and the beginning of September 2016. From these, 34 biological agents already had a QPS status and did not require further evaluation, and 10 were not included in the evaluation as they are filamentous fungi or enterococci, biological groups which have been excluded from QPS evaluation since 2014.

There are a lot of genera in this phylum that are causing various types of infections in humans, animals, and plants. As well as antimicrobial agents that are used in medicine for infections treatment or prevention of infections, they have been discovered of various genera in this phylum. To date, resistance to antibiotics is rising in different regions of the world and this is a global health threat.

Standards in Genomic Sciences (2016) 11:54 DOI 10.1186/s40793-016-0176-4 EXTENDED GENOME REPORT Open Access First high quality draft genome sequence of a plant growth promoting and cold active enzyme producing psychrotrophic Arthrobacter agilis strain L77 Ram N. Singh1, Sonam Gaba1, Ajar N. Yadav1, Prakhar Gaur1, Sneha Gulati1, Rajeev Kaushik1 and Anil K. Saxena1,2* Abstract Arthrobacter agilis strain L77, is a plant growth promoting and cold active hydrolytic enzymes producing psychrotrophic bacterium, isolated from Pangong Lake, a subglacial lake in north western Himalayas, India. Genome analysis revealed metabolic versatility with genes involved in metabolism and cold shock adaptation, utilization and biosynthesis of diverse structural and storage polysaccharides such as plant based carbon polymers. The genome of Arthrobacter agilis strain L77 consists of 3,608,439 bp (3.60 Mb) of a circular chromosome. The genome comprises of 3316 protein coding genes and 74 RNA genes, 725 hypothetical proteins, 25 pseudo-genes and 1404 unique genes. Keywords: Arthrobacter, Psychrotrophic, PGPB, Cold-active enzymes, Pangong Lake, Himalayas Abbreviations: AFCs, Anti-freeze compounds; EPS, Exopolysaccharides Introduction industry, agriculture and biotechnology. Arthrobacter The microorganisms from extreme environments are of agilis [9] strain L77 was isolated from Pangong Lake, a particular importance in global ecology since the major- subglacial lake in north western Himalayas, India and ity of terrestrial and aquatic ecosystems of our planet are exhibit plant growth promoting attributes as well as pro- permanently or seasonally submitted to cold tempera- duction of hydrolytic enzymes.

  • Biodegradation of Poly(Ethylene Terephthalate) by Marine Bacteria, and Strategies for Its Enhancement
    Biodegradation of poly(ethylene terephthalate) by marine bacteria, and strategies for its enhancement Submitted in total fulfillment of the requirements for the degree of Doctor of Philosophy by Hayden Webb Environmental and Biotechnology Centre Faculty of Life and Social Sciences Swinburne University of Technology May 2012 ___________________________________________________________________ Abstract Plastic accumulation, particularly in the world’s oceans is of increasing environmental concern. One of the major components of plastic waste is poly(ethylene terephthalate) (PET), a polymer frequently used in many applications, including textiles and food packaging. The current methods of disposal of PET waste, landfill, incineration and recycling, each have inherent drawbacks and limitations, and as such there is a need for efficient and cost-effective alternative. Biodegradation is an attractive option for environmentally friendly and efficient disposal of plastic waste. To date, no protocol has yet been developed to feasibly dispose of PET by biodegradation con a commercial scale. The current works aims to investigate the potential of PET biodegradation as a plastic disposal procedure by providing fundamental knowledge of biodegradation processes, and to develop strategies for improving biodegradation efficiency. PET samples were incubated in marine bacterial community enrichment cultures, and the dynamics of the polymer – bacterial interactions traced. Modifications to polymer surfaces were monitored using a variety of surface characterisation techniques, including atomic force microscopy (AFM), x-ray photoelectron spectroscopy (XPS) and infrared microspectroscopy using Synchrotron radiation. Taxonomic members of the bacterial enrichment cultures that developed in the presence of PET were recovered and identified via 16S rRNA gene sequencing. Marine bacteria were shown to possess the ability to degrade PET surfaces.
