Lactate dehydrogenase from Streptococcus mutans: purification, characterization, and crossed antigenicity with lactate dehydrogenases from Lactobacillus casei, Actinomyces viscosus, and Streptococcus sanguis

Pascal Sommer、J.P. Klein、M Schöller 等 4 位作者1985-02-01Infection and Immunity

A cytoplasmic fructose-1,6-diphosphate-dependent lactate dehydrogenase (LDH; EC 1.1.1.27) from Streptococcus mutans OMZ175 was purified to homogeneity as judged by sodium dodecyl sulfate-gel electrophoresis. The purification consisted of ammonium sulfate precipitation of the cytoplasmic fraction, DEAE-Sephacel and Blu…

Method for isolating cyanobacteria‐lysing streptomycetes from soil

Lyle G. Whyte、Andrew Maule、D. Roy Cullimore1985-02-01Journal of Applied Bacteriology

A new technique is described for the isolation and enumeration of cyanobacteria‐lysing Streptomyces spp from soil or water. Two cyanobacteria, Anabaena cylindrica (ACTT 27899) and Tolypothrix tenuis (ATCC 27914) were used as the test organisms. Ten‐day‐old cyanobacterial cultures were vacuum‐filtered to form a lawn on…

Finite Element Model for Analysis of Fission Gas Release from UO2Fuel

Kenichi Ito、Ryo Iwasaki、Yoshihiko Iwano1985-02-01Journal of Nuclear Science and Technology

A finite element model is proposed to analyze in-pile fission gas release from UO2 fuel. The model describes fission gas transfer from grain interior to grain boundaries by simultaneous mechanisms of diffusive flow and boundary sweeping, considering the effect of irradiation-induced resolution in grain boundaries. The…

Optical spectra and crystal field analysis of Dy3+ in Cs2NaDyCl6 and Cs2NaYCl6: Dy3+(5 mol %)

David R. Foster、F. S. Richardson1985-02-01The Journal of Chemical Physics

Optical absorption and emission measurements are reported for the Cs2NaDyCl6 and Cs2NaYCl6: Dy3+(5 mol %) systems under variable-temperature (10–298 K) conditions. For both systems, the data are compatible with the retention of octahedral (Oh) site symmetry at the Dy3+ ions over the entire 298 to 10 K temperature rang…

Valence Isomerization between Water-soluble Norbornadiene and Quadricyclane Derivative

Kazuhiro Maruyama、Hitoshi Tamiaki、Tetsuya Yanai1985-02-01Bulletin of the Chemical Society of Japan

Abstract Photoisomerization of 3-(aryicarbamoyl)norbornadiene-2-carboxylic acid 1 to the corresponding quadricyclane derivative 2 in an aqueous alkaline solution was clean and dependent upon the p-substituent of the aryl group. The exothermically reversal reaction of 2 to 1 was also clean but independent upon the subs…
