A Gram-negative, dark orange-pigmented, aerobic, non-spore-forming, coccoid-shaped bacterium designated as ZS-1/3T was isolated from a floating plastic litter (polypropylene straw) sample, collected from shallow seawater near the public beach of Laganas on Zakynthos island, Greece. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate is affiliated with the genus Parvularcula in the family Parvularculaceae. Its closest relatives are Parvularcula lutaonensis (98.09  %) and Parvularcula oceanus (95.89  %). The pH and temperature ranges for growth are pH 5-10 and 20-38 °C (optima, pH 7.0 and 28 °C). The predominant fatty acids are C18  1 ω7c (56.84  %), C16  0 (27.51  %), C18  0 (2.25  %) and C12  0 (1.42  %). The predominant respiratory quinone detected in strain ZS-1/3T is quinone-10 (Q10); the majority of detected polar lipids are glycolipid. The DNA G+C content is 62.5  mol%. Physiological and chemotaxonomic data further confirmed the distinctiveness of strain ZS-1/3T from other members of the genus Parvularcula. Thus, strain ZS-1/3T is considered to represent a novel species of the genus, for which the name Parvularcula mediterranea. sp. nov. is proposed. The type strain is ZS-1/3T (=NCAIM B 02654T=CCM 9032T).Three bacterial strains, designated Red330T, Red736T and Red745T, were isolated from forest and paddy soils in Japan. Strains Red330T, Red736T and Red745T are flagella-harbouring and strictly anaerobic bacteria forming red colonies. A 16S rRNA gene sequence-based phylogenetic tree showed that all three strains were located in a cluster, including the type strains of Geomonas species, which were recently separated from the genus Geobacter within the family Geobacteraceae. Similarities of the 16S rRNA gene sequences among the three strains and Geomonas oryzae S43T, the type species of the genus Geomonas, were 96.3-98.5 %. The genome-related indexes, average nucleotide identity, digital DNA-DNA hybridization, and average amino acid identity, among the three strains and G. oryzae S43T were 74.7-86.8 %, 21.2-33.3 % and 70.4-89.8 %, respectively, which were lower than the species delineation thresholds. Regarding the phylogenetic relationships based on genome sequences, the three strains clustered with the type strains of Geomonas species, which were independent from the type strains of Geobacter species. The distinguishableness of the three isolated strains was supported by physiological and chemotaxonomic properties, with the profile of availability of electron donors and cellular fatty acids composition being particularly different among them. Based on genetic, phylogenetic and phenotypic properties, the three isolates represent three novel independent species in the genus Geomonas, for which the names Geomonas silvestris sp. nov., Geomonas paludis sp. nov. and Geomonas limicola sp. nov. are proposed. The type strains are Red330T (=NBRC 114028T=MCCC 1K03949T), Red736T (=NBRC 114029T=MCCC 1K03950T) and Red745T (=NBRC 114030T=MCCC 1K03951T), respectively.In the present study, the taxonomic positions of five strains (C, 17-2, LMG 10779T, LMG 18969 and LMG 11483) of Leuconostoc pseudomesenteroides were re-evaluated by a polyphasic approach, including the analyses of 16S rRNA, pheS and rpoA gene sequences, cellular fatty acids, average nucleotide and amino acid identities (ANI and AAI), digital DNA-DNA hybridization (dDDH), and phenotypic features. Based on rpoA sequence analysis, the five strains and L. pseudomesenteroides LMG 11482T were divided into two groups strains C, LMG 10779T and LMG 18969; strains 17-2, LMG 11483 and LMG 11482T.  https://www.selleckchem.com/products/ly3522348.html  Each of the two groups had almost identical rpoA sequences. The rpoA sequence similarity between strain LMG 10779T and L. pseudomesenteroides LMG 11482T was 95.6 %. Strains LMG 11483 and 17-2 had 98.1 and 97.2 % ANI values, 83.5 and 73.2 % dDDH values, and a 97.0 % AAI value with L. pseudomesenteroides LMG 11482T, greater than the threshold for species demarcation, indicating that strains LMG 11483 and 17-2 belong to L. pseudomesenteroides. Strains LMG 18969 and C shared 97.1 and 98.2 % ANI values, 73.4 and 83.2 % dDDH values, and 96.9 and 96.6 % AAI values with strain LMG 10779T, greater than the threshold for species demarcation, indicating that strains LMG 10779T, LMG 18969 and C represent the same species. The ANI, dDDH and AAI values between strain LMG 10779T and the type strains of phylogenetically related species were 75.2-92.5, 20.0-48.2 and 75.3-93.9 %, respectively, below the thresholds for species demarcation, indicating that strain LMG 10779T represents a novel species within the genus Leuconostoc. On the basis of the results presented here, (i) strains 17-2 and LMG 11483 belong to L. pseudomesenteroides, and (ii) strains LMG 10779T, LMG 18969 and C are considered to represent a novel species within the genus Leuconostoc, for which the name Leuconostoc falkenbergense sp. nov. is proposed with the type strain LMG 10779T (=CCUG 27119T).The purpose of this study was to shed light on the associations between emotion regulation (ER) strategies used, their emotional processes (including cognitive appraisals and discrete emotions), and subjective performance across a competitive season. A sample of fifteen national-level rink hockey players completed ER questionnaire at the beginning of the season (T0) and reported their experiences of everyday appraisal, emotions, and subjective performance every week. A series of hierarchical linear modelling analyses (HLM) were performed to investigate the associations between the variables. Sobel tests were computed to identify the mediating effects of emotions and appraisals on these relationships. HLM results revealed that (a) T0 adaptive ER strategies were positively related to adaptive appraisals; (b) adaptive appraisals were positively related to pleasant emotions and negatively with unpleasant emotions and opposite relationships emerged for maladaptive appraisals; (c) happiness was positively associated with subjective performance. Sobel tests provided evidence of mediating effects of (a) appraisals in the relationships between T0 adaptive ER and pleasant emotions; and (b) happiness in the relationships between appraisals and subjective performance. The results highlighted the positive relationships between the adaptive dispositional ER strategies at the beginning of the season and the emotional experiences. Moreover, the analyses revealed relationships between appraisals, emotions, and subjective performance of athletes. In sum, this study provided additional knowledge about the capture of the emotional process during a competitive season highlighting the associations between a variety of emotions and selected key variables in a competitive context (i.e. ER strategies, appraisal, subjective performance).
