RESUMO
A Gram-stain-positive, strictly aerobic, non-motile, non-spore-forming and rod-shaped bacterium, designated as strain G-1T, was isolated from farmland soil sampled in in Fuyang, Anhui Province, PR China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain G-1T was closely related to Cumulibacter manganitolerans 2-36T (97.7â% similarity). Strain G-1T contained iso-C16â:â0, C17â:â1ω6c, iso-C15â:â0 and iso-C14â:â0 as the predominant fatty acids. The polar lipids of strain G-1T were diphosphatidylglycerol, phosphatidylethanolamine, an unidentified phospholipid, an unidentified lipid and two unidentified glycolipids. The predominant respiratory quinone of strain G-1T was MK-9(H4). The cell wall contained meso-diaminopimelic acid as the diagnostic diamino acid. The G+C content of the genomic DNA based on genome calculations was 64.2 mol%. Average nucleotide identity and the digital DNA-DNA hybridization values for the draft genomes between strain G-1T and strain 2-36T were 75.7 and 20.2 %, respectively. On the basis of phenotypic and phylogenetic data, strain G-1T is considered to represent a novel species of the genus Cumulibacter, for which the name Cumulibacter soli sp. nov. is proposed. The type strain is G-1T (=CCTCC AB2019021T=KCTC 49258T).

A Gram-stain-positive, aerobic, non-motile and coccoid-shaped bacterium, designated XNB-1T, was isolated from farmland soil in Taian, Shandong province, China. Strain XNB-1T contained iso-C15â:â0 and iso-C16â:â0 as the predominant fatty acids. The diagnostic diamino acid of the peptidoglycan was ornithine, and the interpeptide bridge was l-OrnâGly(1, 2)âd-Glu. The polar lipid profile of strain XNB-1T consisted of diphosphatidylglycerol, phosphatidylglycerol, an unidentified phosphoglycolipid and three unidentified phospholipids. The predominant menaquinone of strain XNB-1T was MK-8(H4) and the DNA G+C content was 70.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain XNB-1T belonged to the genus Ornithinicoccus, and shared the highest similarity with Ornithinicoccus hortensis HKI 0125T (96.0â%), followed by Ornithinicoccus halotolerans EGI 80423T (95.5â%). Genome-based analysis of average nucleotide identity of strain XNB-1T with O. hortensis HKI 0125T and O. halotolerans EGI 80423T yielded values of 73.1 and 73.3â%, respectively, while the digital DNA-DNA hybridization values were 19.5 and 19.9â%, respectively. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain XNB-1T is considered to represent a novel species of the genus Ornithinicoccus, for which the name Ornithinicoccus soli sp. nov. is proposed. The type strain is XNB-1T (=CCTCC AB 2019099T=KCTC 49259T).

A Gram-stain-negative, aerobic, non-motile, non-spore-forming and rod-shaped bacterium, designated YHM-9T, was isolated from soil in Yangquan, Shanxi Province, PR China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YHM-9T belonged to the genus Pedobacter and shared the highest similarity (97.4â%) to the type strain Pedobacter lignilitoris W-WS13T. Strain YHM-9T exhibited low DNA-DNA relatedness with P. lignilitoris W-WS13T (21.7±1.3â%). The DNA G+C content was 38.9 mol%. The major fatty acids were iso-C15â:â0, summed feature 3 (C16â:â1ω7c and/or C16â:â1ω6c) and iso-C17â:â0 3-OH. The respiratory quinone was MK-7, the major polyamine was sym-homospermidine and the major polar lipids were phosphatidylethanolamine. Based on the morphological, physiological, biochemical and chemotaxonomic characteristics, strain YHM-9T was recognized as a representative of a novel species within the genus Pedobacter, for which the name Pedobacteragrisoli sp. nov. is proposed. The type strain is YHM-9T (=JCM 32093T=CCTCC AB 2017125T).

A novel Gram-stain-positive bacterium, designated djl-8T, was isolated from farmland soil in Nanjing, Jiangsu province, PR China. Cells of strain djl-8T were aerobic, non-motile, non-spore-forming and rod-shaped. The organism grew at 25-37 °C, pH 5.5-8.0 and 0.5-4.0â% NaCl (w/v). The DNA G+C content was 69.3 mol%. The diagnostic diamino acid in the cell-wall peptidoglycan was LL-2, 6-diaminopimelic acid. The major fatty acids (>5â%) were iso-C16â:â0, anteiso-C17â:â0, iso-C15â:â0, 10-Me C17â:â0 and C17â:â1ω8c. The respiratory quinone was MK-8 (H4) and the major polar lipids were phosphatidylglycerol, phosphatidylinositol, diphosphatidylglycerol and unknown phospholipids.

OBJECTIVE: To investigate the polymorphisms distribution of genes related with mental diseases, such as proline dehydrogenase gene (PRODH) and serotonin 2A(5-HT(2A)) receptor gene, among Korean-Chinese and Han nationality in Chinese Yanbian area. METHODS: By utilizing techniques of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), the polymorphisms for -1945 region of the PRODH gene and -1438 region of the 5-HT(2A) receptor gene were analyzed. RESULTS: The PRODH genotype frequencies of MM, Mm and mm in Korean-Chinese population were 61.4%,34.4%,4.2% respectively, the allele frequencies were 0.786 for M and 0.214 for m respectively, and those in Han population were 55.2%,38.5%,6.3%, 0.745 and 0.255 respectively. The 5-HT(2A) receptor gene genotype frequencies of AA, AG and GG in Korean-Chinese population were 15.6%,67.7%,16.7% respectively, the allele frequencies were 0.495 for A and 0.505 for G respectively, and those in Han population were 11.5%,65.6%,22.9%, 0.443 for A and 0.557 for G. CONCLUSION: All of the genotype distribution of both loci in Chinese Korean and Han nationality in Yanbian area meet Hardy-Weinberg equilibrium, and show stronger ability in human identity. The data obtained can be used in human identity, paternity testing and Chinese Korean ethnic group study.
