Neopusillimonas aromaticivorans sp. nov. isolated from poultry manure.

A polyphasic taxonomic approach was used to characterize a novel bacterium, designated strain CC-YST667T, isolated from poultry manure sampled in Taiwan. The cells were observed to be aerobic, motile and non-spore-forming rods, displaying positive reactions for oxidase. Optimal growth of CC-YST667T was observed at 25 °C, pH 8.0 and with 1 % (w/v) NaCl. The polar lipid profile consisted of phosphatidylmonomethylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and multiple unidentified polar lipids. The major polyamine was spermidine. The major cellular fatty acids (>5 %) included C16 : 0, C17 : 0cyclo, C19 : 0cyclo ω8c and C14 : 0 3OH/iso-C16 : 1 I. On the basis of the results of analysis of 16S rRNA gene sequences, this isolate showed the closest phylogenetic relationship with 'Neopusillimonas minor' (with 98.2 % similarity) and Paralcaligenes ureilyticus (with 97.3 % similarity) of the family Alcaligenaceae. The draft genome, (3.3 Mb) with a DNA G+C content of 57.2 mol%, harboured various genes involved in the biodegradation of aromatic hydrocarbons. CC-YST667T shared highest orthologous average nucleotide identity (OrthoANI) with the type strains of species of of the genera Neopusillimonas (72.4‒77.9 %, n=2), Pusillimonas (72.8‒73.0 %, n=2) and Pollutimonas (71.7‒73.0 %, n=5). On the basis of its distinct phylogenetic, phenotypic and chemotaxonomic traits together with the results of comparative 16S rRNA gene sequencing, OrthoANI, digital DNA-DNA hybridization (DDH) and the phylogenomic placement, strain CC-YST667T is considered to represent a novel species of the genus Neopusillimonas, for which the name Neopusillimonas aromaticivorans sp. nov. is proposed. The type strain is CC-YST667T (=BCRC 81321T =JCM 34761T).

Description of Pseudogemmobacter faecipullorum sp. nov., isolated from poultry manure.

A polyphasic taxonomic approach was used to characterize a novel bacterium, designated strain CC-YST710T, isolated from poultry manure sampled in Taiwan. Cells of strain CC-YST710T were aerobic, Gram-stain-negative, nonmotile, nonspore-forming rods, displaying positive reactions for catalase, and oxidase activities. Strain CC-YST710T was found to grow optimally at 30°C, pH 7.0, and in the presence of 2% (w/v) NaCl. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, two unidentified phospholipids, four unidentified aminolipids, one unidentified aminophospholipid, and five unidentified lipids. The major polyamine was spermidine. The dominating cellular fatty acids (> 5%) included C16:0, C18:0, and C18:1ω7c/C18:1ω6c. Based on 16S rRNA gene analysis, this isolate showed the closest phylogenetic relationship with 'Pseudogemmobacter humicola' (97.6%), followed by Pseudogemmobacter bohemicus (97.2%) and 'Pseudogemmobacter hezensis' (97.5%). The draft genome (4.3 Mb) had 62.9 mol% G + C content. CC-YST710T can be distinguished from other Pseudogemmobacter species due to the exclusive presence of key genes encoding p-hydroxybenzoate hydroxylase, protocatechuate 3, 4-dioxygenase (α and ß chain), and homogentisate 1, 2-dioxygenase involved in the degradation of phenolic compounds such as p-hydroxybenzoic acid, protocatechuate, and homogentisate, respectively. Orthologous average nucleotide identity (OrthoANI) of the isolate with the type strains of the genera Pseudogemmobacter were 77.6%‒78.0% (n = 3), followed by Tabrizicola (72.3%‒73.7%, n = 5), and Gemmobacter(72.3%‒73.5%, n = 7). Based on its distinct phylogenetic, phenotypic, and chemotaxonomic traits together with results of comparative 16S rRNA gene sequence, OrthoANI, digital DDH, and the phylogenomic placement, strain CC-YST710T is considered to represent a novel Pseudogemmobacter species, for which the name Pseudogemmobacter faecipullorum sp. nov. (type strain CC-YST710T = BCRC 81286T = JCM 34182T).

Pusillimonas faecipullorum sp. nov., isolated from the poultry manure.

A polyphasic taxonomic approach was used to characterize a novel bacterium, designated strain CC-YST705T, isolated from poultry manure sampled in Taiwan. Cells of strain CC-YST705T were aerobic, Gram-stain-negative, non-motile, non-spore-forming rods, displaying positive reactions for catalase, oxidase and ß-glucosidase. Optimal growth occurred at 30 °C and pH 8. Strain CC-YST705T shared the highest (> 96.0%) pair-wise 16S rRNA gene sequence similarity with Pusillimonas noertemannii (96.7%), followed by Pusillimonas caeni (96.6%), Eoetvoesia caeni (96.1%) and Paracandidimonas soli (96.0%), and formed a distinct phyletic lineage associate with the clade that accommodated Pusillimonas species. The draft genome (3.1 Mb) having 57.4 mol % G + C content contained genes involved in the catabolism of aromatic hydrocarbons. The orthologous average nucleotide identity (OrthoANI) values were 62.8-73.1% (n = 8), 72.6 (n = 1), 71.5% (n = 1) compared within the type strains of the genera Pusillimonas, Eoetvoesia and Paracandidimonas, respectively. The polar lipid profile consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, one unidentified aminolipid, two unidentified phospholipids and five unidentified lipids. The major polyamine was spermidine. The dominating cellular fatty acids (> 5%) included C12:0, C16:0, C17:0 cyclo, C19:0 cyclo ω8c and 2 C14:0 3OH/iso-C16:1 I. Based on its distinct phylogenetic, phenotypic and chemotaxonomic traits together with results of comparative 16S rRNA gene sequence, OrthoANI, digital DDH, and the phylogenomic placement, strain CC-YST705T is considered to represent a novel species of the genus Pusillimonas, for which the name Pusillimonas faecipullorum sp. nov. is proposed. The type strain is CC-YST705T (= BCRC 81285 T = JCM 34168 T).

Description of Devosia faecipullorum sp. nov., harboring antibiotic- and toxic compound-resistace genes, isolated from poultry manure.

A polyphasic taxonomic approach was used to characterize a Gram-stain-negative bacterium, designated strain CC-YST696T, harbouring antibiotic- and toxic compound-resistace genes, isolated from poultry manure in Taiwan. Cells of CC-YST696T were short rods, motile with polar flagella, catalase- and oxidase-positive. Optimal growth occurred at 30 °Ð¡, pH 9 and with 1 % NaCl. The results of phylogenetic analyses based on 16S rRNA genes revealed a distinct taxonomic position attained by CC-YST696T associated with Devosia chinhatensis (97.9 % sequence identity), Devosia riboflavina (97.3 %) and Devosia indica (97.2 %), and with lower sequence similarity values to other species. Average nucleotide identity (ANI) values were 72.8-80.0 % (n=17) compared within the type strains of species of of the genus Devosia. CC-YST696T contained C16:0, C18:0, C18:1ω7c 11-methyl and C18:1ω6c/ C18:1ω7c as the predominant fatty acids. The polar lipid profile consisted of phosphatidylethanolamine, phosphatidylglycerol, two unidentified aminolipids, three unidentified glycolipids, two unidentified phospholipids and three unidentified lipids. The DNA G+C content was 62.2 mol% and the predominant quinone was ubiquinone Q-10. On the basis of its distinct phylogenetic, phenotypic and chemotaxonomic traits together with results of comparative 16S rRNA gene sequence and ANI analyses, strain CC-YST696T is proposed to represent a novel species of the genus Devosia, for which the name Devosia faecipullorum sp. nov. (type strain CC-YST696T=BCRC 81284T=JCM 34167T) is proposed.
