“…However, L. a aggregata has not previously been reported to have growth-promoting activity in plants. The bacterium Litorivivens lipolytica was previously characterized from a tidal flat of the South China Sea, and Pelagibacterium halotolerans was identified from seawater in China [ 43 , 44 ]. Marinobacter guineae is a moderately halophilic bacterium previously isolated from Antarctica [ 45 ] and was recently reported as a potential source of long-chain polyunsaturated fatty acids [ 46 ].…”

Some genotypes of date palms (Phoenix dactylifera L.) are salt-tolerant; however, salinity significantly affects others. This study aimed to determine the root epiphytic bacterial contributions to the salt tolerance mechanism in the date palm and to verify if the salt-tolerant “Umsila” and the salt-susceptible “Zabad” cultivars have different bacterial communities. Therefore, the epiphytic bacterial community structures were investigated in both cultivars when grown under control and salinity conditions. The proximal soils of the roots were collected, the DNA was extracted, and a culture-independent approach using Illumina® MiSeq™ sequence analysis was carried out to identify the changes in the bacterial community structures in the soil samples due to the changes in salinity and the genotypes of the plants based on 16S rRNA gene sequencing. While salt tolerance response differences were evident between the two cultivars, the 16S rRNA gene sequencing results revealed 771 operational taxonomic units (OTUs), including 62 that were differentially accumulated in response to salinity. The ordination analysis showed significant (p = 0.001) changes among the communities in response to salinity in both cultivars. However, the results showed that the two cultivars had distinct bacterial communities when grown under controlled conditions, whereas they had a more similar bacterial community structure when grown under salinity conditions. The plant genotype does not affect the epiphyte bacterial community structure under salinity, probably because salinity affects the plant-microbe interaction similarly in both cultivars. Also, the identified rhizospheric bacteria are not directly associated with the root’s physiological processes in response to salinity.

A Gram-stain-negative, strictly aerobic, beige-pigmented, motile, chemoheterotrophic, rod-shaped or ovoid bacterium, designated strain KMU-37, was isolated from seawater at Najeong Beach in the Republic of Korea. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the novel isolate was affiliated with the genus Litorivivens, class Gammaproteobacteria, showing highest sequence similarity (97.4%) to Litorivivens lipolytica HJTF-7. The DNA-DNA relatedness values between strains KMU-37 and L. lipolytica HJTF-7 were 11.5 ± 0.4%. The DNA G+C content of strain KMU-37 was determined to be 53.8 mol%. Ubiquinone 8 (Q-8) was the sole respiratory quinone. The predominant cellular fatty acids were C17:1 ω8c and C16:1 ω7c and/or C16:1 ω6c. Strain KMU-37 had phosphatidylethanolamine, phosphatidylglycerol and an unidentified lipid as polar lipids. From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, the strain is considered to represent a novel species of the genus Litorivivens for which the name Litorivivens aequoris sp. nov. is proposed. The type strain of L. aequoris sp. nov. is KMU-37 (= KCCM 90262 = NBRC 111904).

A lipolytic bacterial strain, designated BPTF-M5, was isolated from a tidal flat sediment of the Yellow Sea in Republic of Korea, and identified by a polyphasic taxonomic approach. It was Gram negative, aerobic, non-motile and rod shaped. Strain BPTF-M5 grew optimally at 30 °C and in the presence of 2.0-3.0% (w/v) NaCl. A neighbour-joining phylogenetic tree of 16S rRNA gene sequences showed that strain BPTF-M5 fell within the clade comprising the type strains of Pseudoruegeria species. The novel strain exhibited the highest 16S rRNA gene sequence similarity value (98.6%) to Pseudoruegeria marinistellae SF-16. Strain BPTF-M5 exhibited sequence similarities of 97.0-98.5% to the type strains of five other Pseudoruegeria species and of less than 96.1% to other recognized species. Strain BPTF-M5 contained Q-10 as the predominant ubiquinone and C ω7c as the major fatty acid. Phosphatidylglycerol, one unidentified aminolipid, one unidentified lipid and one unidentified glycolipid were detected as major polar lipids in the novel strain. The DNA G + C content of strain BPTF-M5 was 63.3 mol%. DNA-DNA relatedness values between strain BPTF-M5 and the type strains of the six Pseudoruegeria species were 11.0-24.3%. The phenotypic properties of strain BPTF-M5 were clearly distinguished from those of the type strains of the six Pseudoruegeria species. Based on the polyphasic data presented, strain BPTF-M5 represents a novel species of the genus Pseudoruegeria, for which the name Pseudoruegeria litorisediminis sp. nov. is proposed. The type strain is BPTF-M5 (= KCTC 62420 = KACC 19613 = NBRC 113189).
