Abstract

A novel Gram-reaction-negative, rod-shaped, aerobic and motile strain, designated MEBiC06469 T , was isolated from tidal flat sediment of the Taean province, South Korea. Strain MEBiC06469 T produced ivory-coloured colonies on marine agar 2216 medium and could degrade carboxymethyl-cellulose. On the basis of 16S rRNA gene sequence similarity, the closest relative was Pseudomaricurvus alkylphenolicus KU41G T with 96.5 % similarity. The isolate was catalase-positive but oxidase-negative. Growth was observed at 16-38 8C (optimum, 32 8C), at pH 6.0-9.0 (optimum, pH 7.5) and in the presence of 0.0-8.0 % (w/v) NaCl (optimum, 1.5 %). The only isoprenoid quinone was Q-8.The dominant fatty acids were summed feature 3 (comprised of C 15 : 0 2-OH and/or C 16 : 1 v7c; 20.4 %) and C 17 : 1 v8c (30.9 %), summed feature 8 (comprised of C 18 : 1 v7c and/or C 18 : 1 v6c; 9.5 %), C 16 : 0 (9.0 %), C 15 : 1 v8c (5.3 %), and C 11 : 0 3-OH (5.2 %). Based on these phenotypic properties and phylogenetic data, strain MEBiC06469 T should be classified as a novel species within the genus Pseudomaricurvus for which the name Pseudomaricurvus alcaniphilus sp. nov. is proposed. The type strain is MEBiC06469 T (5KCCM 42976 T 5JCM 18313 T). Emended descriptions of the genus Pseudomaricurvus, Pseudomaricurvus alkylphenolicus Iwaki et al. 2014, and Maricurvus nonylphenolicus Iwaki et al. 2012 are also provided.

Aestuariicella albida sp. nov., isolated from surface water of the Yellow Sea, and proposal of the genus Aestuariicella as a member of the family Cellvibrionaceae

“…As mentioned above, phylogenetic analysis suggested that the genus Aestuariicella was closely related to several genera of the family Cellvibrionaceae : Exilibacterium [33], Maricurvus [38], Pseudomaricurvus [39, 40] and Pseudoteredinibacter [41]. In terms of chemotaxonomic analyses, the predominant isoprenoid quinone of the genus Aestuariicella was ubiquinone-8 (Q-8), which is consistent with the four genera.…”

Evaluation of compost, vegetable and food waste as amendments to improve the composting of NaOH/NaClO-contaminated poultry manure

“…The Atopostipes and Lactobacillus genera were less reported in previous compost studies, probably due to their lower tolerance to compost thermophilic temperatures [ 45 , 46 ]. In contrast, Pseudomaricurvus and Thiopseudomonnas have been noted in the middle stage compost of other composting studies, due to their properties of polysaccharide and lignocellulosic degradation and tolerance to high salinity [ 47 , 48 ]. Further efforts will be conducted to isolate these specific bacterial genera, investigate their metabolism and evaluate their potential usage as compost inocula.…”

Exilibacterium tricleocarpae gen. nov., sp. nov., a marine bacterium from coralline algae Tricleocarpa sp.

“…It was reported that A. hydrocarbonica SM-6 T has PE and PG as major polar lipids [30]. However, M. nonylphenolicus KU41E T contained DPG as a major polar lipid [35]. These chemotaxonomic parameters furtherly distinguished strain R142 T from closely related type strains.…”
