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)
The anaerobic packed-bed (AP) and hybrid packed-bed (HP) reactors containing methanogenic microbial consortia were applied to treat synthetic soft drink wastewater, which contains polyethylene glycol (PEG) and fructose as the primary constituents. The AP and HP reactors achieved high COD removal efficiency (>95%) after 80 and 33 days of the operation,(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)
Upflow anaerobic sludge blanket (UASB) reactor has served as an effective process to treat industrial wastewater such as purified terephthalic acid (PTA) wastewater. For optimal UASB performance, balanced ecological interactions between syntrophs, methanogens, and fermenters are critical. However, much of the interactions remain unclear because UASB have(More)
Anaerobic digestion is a common technology to biologically stabilize wasted solids produced in municipal wastewater treatment. Its efficiency is usually evaluated by calculating the reduction in volatile solids, which assumes no biomass growth associated with digestion. To determine whether this assumption is valid and further evaluate digestion efficiency,(More)
