Catalyst-Free α--Selective Hydroboration and ()-Selective Deuterated Semihydrogenation of Alkynyl Sulfones.

Here, we present a straightforward α--selective hydroboration of alkynyl sulfones with NHC-boranes without the need for a catalyst. This reaction is compatible with a wide range of substrates for efficiently producing structurally diverse α-borylated vinyl sulfones in satisfactory yields. The hydride transfer from NHC-borane to alkynyl triflone is studied by density functional theory (DFT) calculations for -hydroboration.

Ancylobacter mangrovi sp. nov., a novel endophytic bacterium isolated from mangrove plant.

Two novel strains GSK1Z-4-2 and MQZ15Z-1 were isolated from branches of mangrove plants collected from Guangxi Zhuang Autonomous Region, China. Both strains were Gram-negative, aerobic, non-flagellated and non-spore-forming bacteria. The comparison of 16S rRNA gene sequences initially indicated that the two strains were assigned to the genus Ancylobacter with sharing the highest similarity to Ancylobacter pratisalsi DSM 102029 (97.

sp. nov., a novel endophytic bacterium isolated from bark of .

A endospore-forming bacterium, designated strain KQZ6P-2, was isolated from surface-sterilized bark of the mangrove plant , collected from Maowei Sea Mangrove Nature Reserve in Guangxi Zhuang Autonomous Region, China. Strain KQZ6P-2 was able to grow at NaCl concentrations in the range of 0-3 % (w/v) with optimum growth at 0-1 % (w/v) NaCl. Growth occurred at 20-42 °C (optimal growth at 30-37 °C) and pH 5.

Description and genomic characterization of Nocardioides bruguierae sp. nov., isolated from Bruguiera gymnorhiza.

Strains BSK12Z-3 and BSK12Z-4, two Gram-stain-positive, aerobic, non-spore-forming strains, were isolated from Shankou Mangrove Nature Reserve, Guangxi Zhuang Autonomous Region, China. The diagnostic diamino acid in the cell-wall peptidoglycan of strain BSK12Z-3 was LL-diaminopimelic acid and MK-8(H) was the predominant menaquinone. The polar lipids comprised diphosphatidylglycerol (DPG), phosphatidylglycerol (PG) and phospholipid (PL).

Jiella avicenniae sp. nov., a novel endophytic bacterium isolated from bark of Avicennia marina.

A Gram-stain-negative and short rod-shaped strain CBK1P-4, isolated from surface-sterilized bark of Avicennia marina was investigated by a polyphasic taxonomic approach to resolve its taxonomic position. Strain CBK1P-4 grew at 10-30 °C (optimum, 25 °C), pH 5.0-9.

sp. nov., a novel endophytic bacterium isolated from bark of .

A new endophytic bacterium, designated strain MQZ13P-4 was isolated from collected from Maowei sea Mangrove Nature Reserve in Guangxi Zhuang Autonomous Region, PR China. The 16S rRNA gene sequence similarity between strain MQZ13P-4 and its closest phylogenetic neighbour CBS5Q-3 was 97.9 %.

sp. nov., a novel endophytic actinobacterium isolated from root of .

A novel species of endophytic actinobacterium, designated strain GBK3QG-3, was isolated from surface-sterilized root of collected from Beilun Estuary, Guangxi Zhuang Autonomous Region, PR China. Cells of strain GBK3QG-3 were Gram-stain-positive, aerobic, non-spore-forming and rod-shaped. Growth of GBK3QG-3 was observed at 10-40 °C (optimum, 30 °C), pH 5.

sp. nov., a novel endophytic bacterium isolated from bark .

A Gram-stain-negative, aerobic, short-rod-shaped bacterium, designated strain CBS1P-1, was isolated from a surface-sterilized bark of . Growth of strain CBS1P-1 was observed with between 0 and 12.0 % (w/v) NaCl (optimally with 5.
