A Gram-negative, short rod-shaped, floc-forming bacterial strain J5-66T without any flagellum was isolated from coking wastewater collected from Shaoguan, Guangdong, China. It was capable of optimal growth at pH 7, 30 °C, and 1–2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that this strain belonged to the genus Ottowia in(More)
Two Gram-negative, non-motile, short-rod-shaped bacterial isolates, designated 110399T and 110248, were isolated from an oil-polluted saline soil in Shengli Oilfield, Eastern China. The two strains shared 99.9 % 16S rRNA gene sequence similarity with the DNA–DNA relatedness value being 80.0 %. They were both capable to grow at 20–40 °C, pH 7–9, and 1–9 %(More)
A Gram staining negative, rod-shaped, aerobic bacterial strain J5-3T with a single polar flagellum was isolated from coking wastewater collected from Shaoguan, Guangdong, China. It was motile and capable of optimal growth at pH 6–8, 30 °C, and 0–2 % (w/v) NaCl. Its predominant fatty acids were 11-methyl C18:1 ω7c (29.2 %), C16:0 (20.6 %), C19:0 cyclo ω8c(More)
This study demonstrates a new process for preparation of oil-in-water (O/W) emulsion using the high gravity technique. This involves a mixture of oil and water that are passed through a rotating packed bed, under a high shear force, from which oil is emulsified into tiny droplets and subsequently dispersed in water. The process is cycled in order to break(More)
A bacterial strain designated 6B-8(T) was isolated from crude oil from Daqing oilfield, China. Cells of strain 6B-8(T) were Gram-negative, aerobic, dimorphic and reproduced by means of binary fission. Strain 6B-8(T) could grow at 20-37 °C, pH 8-10 and 1-5 % (w/v) NaCl. Its genomic DNA G+C content was 62.0 mol%. The predominant cellular fatty acids were C18(More)
In this work, we demonstrate a strategy to control the accumulation of water in the oil-solid interface using a gradient coating. Gradient chemistry on glass surface is created by vapor diffusion of organosilanes, leading to a range of contact angles from 110 to 20°. Hexadecane is placed on the gradient substrate as an oil layer, forming a(More)
Two Gram-stain-negative, rod-shaped bacterial strains, cai42T and b45, were isolated from oil-production water taken from Xinjiang Oilfield, China. Optimum growth was observed at 30 °C, at pH 8 and with 1-3% (w/v) NaCl. According to phylogenetic analyses, the two strains were members of the genus Defluviimonas, with 16S rRNA gene sequence similarities of(More)
