A new iron oxidase from a moderately thermophilic iron oxidizing bacterium strain TI-1.
TLDR
Purified enzyme from strain TI-1 is a new iron oxidase in which electrons of Fe(2+) were transferred to haem a and then to the molecular oxygen, and the activity was strongly inhibited by cyanide and azide. Expand
Isolation and Some Properties of an Iron-Oxidizing Bacterium Thiobacillus ferrooxidans Resistant to Bisulfite Ion
Among seventy five strains of iron-oxidizing bacteria obtained from natural environments, only one strain, Thiobacillus ferrooxidans Funis 2-1, grew on Fe2+-medium with 1.25 mm of sodium molybdateExpand
Isolation and some properties of a moderately thermophilic iron-oxidizing bacterium
TLDR
Strain TI-1 was a Gram negative, non-spore-forming, and rod-shaped bacterium, which had a optimum temperature and pH for growth at 48°C and 2.2, and the mean G+C content of the DNA was 56.2 mol%. Expand
Growth of moderately thermophilic iron-oxidizing bacterium strain TI-1 in synthetic medium
TLDR
Reduction of Fe 3+ to Fe 2+ that was dependent on the added amino acids was observed, suggesting another role of the amino acids in the growth of strain TI-1. Expand
Purification and characterization of sulfur reductase from a moderately thermophilic bacterial strain, TI-1, that oxidizes iron.
A moderately thermophilic bacterium, strain TI-1, produces H2S outside of the cells when grown at 45 degrees C on Fe(2+)-medium (pH 1.8) containing elemental sulfur and L-glutamic acid. A newlyExpand
Involvement of cytochrome a in iron oxidation of a moderately thermophilic iron-oxidizing bacterium, strain TI-1.
TLDR
The results strongly suggest that cytochrome a, but not cytochromes b and c, is involved in iron oxidation of strain TI-1. Expand
Production of hydrogen sulfide by a moderately thermophilic iron-oxidizing bacterium strain TI-1
Abstract A moderately thermophilic iron-oxidizing bacterium strain TI-1 has been shown to have a unique enzyme system that produces hydrogen sulfide (H2S) extracellularly under acidic conditions. TheExpand
Wet heat inactivation of lipopolysaccharide from E. coli serotype 055:B5.
TLDR
The initial slopes are associated with a faster rate of decrease to about a 0.5-log unit reduction, and were followed by a slower, linear rate of decline in the secondary slopes, which indicates the processes required to achieve the desired level of LPS inactivation can be obtained by mathematical means.

Molecular diversity of cytochrome oxidase among Acidithiobacillus ferrooxidans strains resistant to molybdenum, mercury, sulfite and 2,4-dinitrophenol
Abstract Five physiologically different strains of Acidithiobacillus ferrooxidans were isolated. Strains Funis 2-1, SUG 2-2, OK1-50 and NASF-1, respectively, are resistant to molybdenum, mercury,Expand
Boron Trifluoride Etherate-catalyzed Backbone Rearrangement of 5α,10α-Epoxyalnusan-3β-yl Acetate and Partial Synthesis of Isomultiflorenol
Epoxidation of alnus-5(10)-en-3β-yl acetate with m-chloroperbenzoic acid gave a 5α,10α-epoxide, treatment of which with boron trifluoride etherate afforded multiflora-5,8-dien-3β-yl acetate. OnExpand
