摘要:Abstract(#br)The present study describes succession in the abundances of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in the upland and flooded bulk soils of a Japanese rice paddy field over 2 years using a quantitative polymerase chain reaction of both cr...

摘要:Abstract(#br)We isolated four new ammonia-oxidizing bacterial strains from leucaena ( Leucaena leucocephala ) grown in fields of an acid sulfate soil (ASS) in Thailand; 17SS from the surface soil and 17RS from the rhizoplane of a non-limed plot; 9SS from the surface soil and...

摘要:Abstract(#br)The phylogenetic relationship of β -proteobacterial ammonia-oxidizing bacteria (AOB) is mainly based on comparative sequence analyses of the genes encoding the 16S rRNA (16S rDNA) and the active site polypeptide of the ammonia monooxygenase (AmoA). However, clas...

摘要:Abstract(#br)An ammonia-oxidizing bacterium, strain PJA1, and nitrite-oxidizing bacterium, strain PJN1, were newly isolated from the rhizoplane of barley. The cells of strain PJA1 were lobate, compartmentalized, and showed characteristics of the genus Nitrosolobus . The simi...

摘要:Abstract(#br)Long-term preservation of ammonia-oxidizing bacteria had been achieved until now by using the silica gel-freezing method. Recently, the freeze-drying method for the preservation of microorganisms has been widely used, and has been applied to the preservation of ...

摘要:Abstract(#br)An ammonia-oxidizing bacterium, strain TCH716, was isolated from alkaline soil at Harbin city, China. The cells of strain TCH716 are lobate (0.8–1.5×1.0–2.0 μm), gram-negative, obligately aerobic, and nonmotile. Colonies (1–2 mm in diameter) on gellan gum p...

摘要:Abstract(#br)Nitrosospira, Nitrosolobus , and Nitrosovibrio , three genera of ammonia-oxidizing bacteria (AOB), are morphologically distinct from each other ( Nitrosospira : spiral, Nitrosolobus : lobate, Nitrosovibrio : slender curved rods). However, these three genera cannot be...

摘要:Abstract(#br)A high-concentration-ammonium sulfate-requiring, ammonia-oxidizing bacterium, strain K1, was newly isolated from packed tower biological deodorization plants of chicken farms. The cells of strain K1 are rods (0.1–1.0 × 1.0–2.0 μm), gram negative, obligately...

摘要:The three previously recognized genera of ‘ Nitrosolobus ’, Nitrosospira and ‘ Nitrosovibrio ’ were combined into one genus, Nitrosospira , on the basis of 16S rDNA sequence similarities. However, this classification has been controversial for some time, since the marke...

摘要:Abstract(#br)Triosephosphate isomerases [TIMs, EC 5.3.1.1] were purified from two ammonia-oxidizing bacteria: Nitrosomonas sp. K1 (K1), Nitrosomonas sp. TNO632 (TNO). The molecular masses of the native enzymes were estimated to be about 53.6 (K1-TIM) and 51.9 kDa (TNO-TIM) b...
