Abstract
Bacterial strain Y-6T, isolated from a landfill site in Yiwu, PR China, was characterized using a polyphasic taxonomy approach. Cells were Gram-stain-negative, aerobic, rod-shaped, motile by means of a single polar flagellum and formed pale beige colonies. Strain Y-6T grew at 4-40 °C (optimal at 30-37 °C), pH 6.5-9.5 (optimal at pH 7.2-8.5) and in the presence of 0.5-10.0 % (w/v) NaCl (optimal at 1.0-3.0 %). Phylogenetic analysis revealed that strain Y-6T was a member of the genus Aliidiomarina and closely related to Aliidiomarina taiwanensis MCCC 1A06493T with a 16S rRNA sequence similarity of 98.2 %. The major cellular fatty acids of the isolate were iso-C15 : 0, C16 : 0, iso-C17 : 0 and summed feature 9 (iso-C17 : 1 ω9c and/or 10-methyl-C16 : 0). Q-8 was the predominant ubiquinone. The major polar lipids comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, aminoglycophospholipid, aminophospholipid, phospholipid, three glycolipids and two unknown lipids. The genomic DNA G+C content was 46.6 mol%. The digital DNA-DNA hybridization value between Y-6T and A. taiwanensis MCCC 1A06493T was 18.3 %. Strain Y-6T had an average nucleotide identity value of 74.09 % with A. taiwanensis MCCC 1A06493T. Results from the polyphasic taxonomy study support the conclusion that strain Y-6T represents a novel Aliidiomarina species, for which the name Aliidiomarina quisquiliarum sp.nov. is proposed. The type strain is Y-6T (=MCCC 1K06228T=KCTC 82676T).

Abstract
A haloalkaliphilic strain (IM 1326T) was isolated from brine sampled at a soda lake in the Inner Mongolia Autonomous Region, China. Cells of the strain were rod-shaped and motile. Strain IM 1326T was able to grow at 4–42 °C (optimum, 37 °C) with 0–13.0 % (w/v) NaCl concentrations (optimum at 4.0–6.0 %) and at pH 7.5–11.0 (optimum at 9.0–10.0). The 16S rRNA gene phylogenetic analysis revealed that the isolate belongs to the genus Aliidiomarina and is closely related to the type strains of Aliidiomarina sanyensis (95.8 % sequence similarity), Aliidiomarina shirensis (95.7 %), Aliidiomarina iranensis (95.4 %) and Aliidiomarina haloalkalitolerans (95.3 %). The whole genome of strain IM 1326T was sequenced, and the genomic DNA G+C content was 49.7 mol%. Average nucleotide identity, average amino acid identity and digital DNA–DNA hybridization values between the isolate and the related Aliidiomarina species were 68.1–84.9 %, 76–78 % and 18.4–20.4 %, respectively. The respiratory quinone was ubiquinone-8. The polar lipid profile included diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and one unidentified aminophospholipid. The predominant cellular fatty acids were summed feature 9 (10-methyl-C16 : 0/iso-C17 : 1 ω9c, 22.2 %), iso-C15 : 0 (16.1 %) and iso-C17 : 0 (13.1 %). Based on the results of phylogenetic analysis, genome relatedness, and the physiological and chemotaxonomic properties of the isolate, strain IM 1326T is considered to represent a novel species of the genus Aliidiomarina, for which the name Aliidiomarina halalkaliphila sp. nov. is proposed (type strain IM 1326T=CGMCC 1.17056T=JCM 34227T).

Abstract
A Gram-stain-negative, rod-shaped bacterial strain, designated SW123T, was isolated from a deep-sea water sample collected from the Indian Ocean. Strain SW123T was strictly aerobic, catalase- and oxidase-positive. The predominant cellular fatty acids were iso-C15 : 0, iso-C17 : 0 and summed feature 9 (comprising C16 : 0-methyl or iso-C17 : 1 ω9c). Ubiquinone-8 was the sole respiratory quinone. The major polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. The genomic DNA G+C content was 49.4 mol%. 16S rRNA gene sequence analysis showed that strain SW123T was closely related to Aliidiomarina shirensis AIST (96.7 % sequence similarity), Aliidiomarina iranensis GBPy7T (96.3%), Aliidiomarina haloalkalitolerans AK5T (96.0%) and Aliidiomarina celeris F3105T (95.9%). Phylogenetic trees based on 16S rRNA gene sequences showed that strain SW123T represented a novel member of the genus Aliidiomarina, forming a distinct cluster with A. celeris F3105T. On the basis of phylogenetic inference and phenotypic characteristics, we propose that strain SW123T represents a novel species of the genus Aliidiomarina, with the name Aliidiomarina indica sp. nov. The type strain is SW123T (=CGMCC1.16169T=KCTC 82234T).

A novel alkaline protease from alkaliphilic Idiomarina sp. C9-1 with potential application for eco-friendly enzymatic dehairing in the leather industry. Sci Rep 2018; 8:16467. [PMID: 30405184 PMCID: PMC6220337 DOI: 10.1038/s41598-018-34416-5] [Citation(s) in RCA: 39] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2018] [Accepted: 08/29/2018] [Indexed: 12/27/2022] Open
Abstract
Alkaline proteases have a myriad of potential applications in many industrial processes such as detergent, food and feed production, waste management and the leather industry. In this study, we isolated several alkaline protease producing bacteria from soda lake soil samples. A novel serine alkaline protease (AprA) gene from alkaliphilic Idiomarina sp. C9-1 was cloned and expressed in Escherichia coli. The purified AprA and its pre-peptidase C-terminal (PPC) domain-truncated enzyme (AprA-PPC) showed maximum activity at pH 10.5 and 60 °C, and were active and stable in a wide range of pH and temperature. Ca2+ significantly improved the thermostability and increased the optimal temperature to 70 °C. Furthermore, both AprA and AprA-PPC showed good tolerance to surfactants and oxidizing and reducing agents. We found that the PPC domain contributed to AprA activity, thermostability and surfactant tolerance. With casein as substrate, AprA and AprA-PPC showed the highest specific activity of 42567.1 U mg−1 and 99511.9 U mg−1, the Km values of 3.76 mg ml−1 and 3.98 mg ml−1, and the Vmax values of 57538.5 U mg−1 and 108722.1 U mg−1, respectively. Secreted expression of AprA-PPC in Bacillus subtilis after 48 h cultivation resulted in yield of 4935.5 U ml−1 with productivity of 102.8 U ml−1 h−1, which is the highest reported in literature to date. Without adding any lime or sodium sulfide, both of which are harmful pollutants, AprA-PPC was effective in dehairing cattle hide and skins of goat, pig and rabbit in 8–12 h without causing significant damage to hairs and grain surface. Our results suggest that AprA-PPC may have great potentials for ecofriendly dehairing of animal skins in the leather industry.
