However, substrate-specific bacterial dynamics in a mixture of particle types with different polysaccharide composition, as likely occurring in natural habitats, are undescribed. -
Raineya Orbicola Gen. Nov., Sp. Nov. a Slightly Thermophilic Bacterium of the Phylum Bacteroidetes and the Description of Raineyaceae Fam
TAXONOMIC DESCRIPTION Albuquerque et al., Int J Syst Evol Microbiol 2018;68:982–989 DOI 10.1099/ijsem.0.002556 Raineya orbicola gen. nov., sp. nov. a slightly thermophilic bacterium of the phylum Bacteroidetes and the description of Raineyaceae fam. nov.

Froufe,2 Olga Lage,3,4 Alexandre Lobo-da-Cunha,4,5 Conceiçao~ Egas1,2 and Milton S. da Costa1,* Abstract An isolate, designated SPSPC-11T, with an optimum growth temperature of about 50 C and an optimum pH for growth between 7.5 and 8.0, was recovered from a hot spring in central Portugal. Based on phylogenetic analysis of its 16S rRNA sequence, the new organism is most closely related to the species of the genus Thermonema but with a pairwise sequence similarity of <85 %. The isolate was orange-pigmented, formed non-motile long filaments and rod-shaped cells that stain Gram-negative. The organism was strictly aerobic, oxidase-positive and catalase-positive. The major fatty acids were iso- C15:0, iso-C15 : 0 2-OH and iso-C17 : 0 3-OH. The major polar lipids were one aminophospholipid, two aminolipids and three unidentified lipids. Menaquinone 7 was the major respiratory quinone. The DNA G+C content of strain SPSPC-11T was 37.6 mol% (draft genome sequence). The high quality draft genome sequence corroborated many of the phenotypic characteristics of strain SPSPC-11T. Based on genotypic, phylogenetic, physiological and biochemical characterization we describe a new species of a novel genus represented by strain SPSPC-11T (=CECT 9012T=LMG 29233T) for which we propose the name Raineya orbicola gen. -

CCB- QB2 was isolated from seaweed Malaysia Kelantan, Jeli, Malaysia (genus Ulva) collected from a coastal area of Malaysia. Here, we report a high- quality 3School of Biological Sciences, Universiti draft genome sequence for QB2. The Rapid Annotation using Subsystem Technology Sains Malaysia, Minden, Malaysia (RAST) annotation server identified four β-agarases (PdAgaA, PdAgaB, PdAgaC, and Correspondence PdAgaD) as well as galK, galE, and phosphoglucomutase, which are related to the Go Furusawa Centre for Chemical Biology, Universiti Sains Leloir pathway. Interestingly, QB2 exhibited a diauxic growth in the presence of two Malaysia, Penang, Malaysia. kinds of nutrients, such as tryptone and agar. In cells grown with agar, the profiles of Email: [email protected] agarase activity and growth rate were very similar. galK, galE, and phosphogluco- mutase genes were highly expressed in the second growth phase of diauxic growth, indicating that QB2 cells use galactose hydrolyzed from agar by its agarases and ex- hibit nutrient prioritization. This is the first report describing diauxic growth for agaro- lytic bacteria. QB2 is a potential novel model organism for studying diauxic growth in environmental bacteria.

Beatty, Lauren A. Paul, William Fenical and Paul R. Jensen Correspondence Center for Marine Biotechnology and Biomedicine, Scripps Institution of Oceanography, University Paul R. Jensen of California San Diego, La Jolla, CA 92093-0204, USA [email protected] Bacterial strains CNX-216T and CNU-914T were isolated from marine sediment samples collected from Palmyra Atoll and off Catalina Island, respectively. Both strains were Gram- negative and aerobic and produce deep-orange to pink colonies and alkaloid secondary metabolites. Cells of strain CNX-216T were short, non-motile rods, whereas cells of strain CNU- 914T were short, curved rods with gliding motility. The DNA G+C contents of CNX-216T and CNU-914T were respectively 57.7 and 44.4 mol%. Strains CNX-216T and CNU-914T contained MK-7 as the predominant menaquinone and iso-C15 : 0 and C16 : 1v5c as the major fatty acids. Phylogenetic analyses revealed that both strains belong to the order Cytophagales in the phylum Bacteroidetes. Strain CNX-216T exhibited low 16S rRNA gene sequence identity (87.1 %) to the nearest type strain, Cesiribacter roseus 311T, and formed a well-supported lineage that is outside all currently described families in the order Cytophagales. Strain CNU-914T shared 97.6 % 16S rRNA gene sequence identity with ‘Porifericola rhodea’ N5EA6-3A2B and, together with ‘Tunicatimonas pelagia’ N5DB8-4 and four uncharacterized marine bacteria isolated as part of this study, formed a lineage that is clearly distinguished from other families in the order Cytophagales. -

The novel strain grew optimally at 30–37 6C and in the presence of 2 % (w/v) sea salts. The only respiratory quinone detected was MK-7 and the major cellular fatty acids were summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1v7c), iso-C15 : 0 and iso-C17 : 0 3-OH. The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, an unidentified aminolipid and two unidentified aminophospholipids. The DNA G+C content was 45.4 mol%. Flexirubin-type pigments were not produced. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain ZLM-10T was a member of the phylum Bacteroidetes and appeared most closely related to Cesiribacter roseus 311T (90.2 % sequence similarity), Marivirga sericea LMG 13021T (89.2 %), Cesiribacter andamanensis AMV16T (89.1 %) and Marivirga tractuosa DSM 4126T (89.1 %). -
