Racemic Resolution of some dl-Amino Acids using Aspergillus fumigatusl-Amino Acid Oxidase
Get PDFThe ability of Aspergillus fumigatus L-amino
acid oxidase (L-aao) to cause the resolution of racemic
mixtures of DL-amino acids was investigated with DL-alanine,
DL-phenylalanine, DL-tyrosine, and DL-aspartic acid.A

the amino acids. The enzyme was able to cause the resolution
of the three DL-amino acids resulting in the production
of optically pure D-alanine (100% resolution),
D-phenylalanine (80.2%), and D-tyrosine (84.1%), respectively.
The optically pure D-amino acids have many uses
and thus can be exploited industrially. This is the first
report of the use of A. fumigatus L-amino acid oxidase for
racemic resolution of DL-amino acids

Get PDFGround motion parameters in Shillong and Mikir Plateau supplemented by mapping of amplification factors in Guwahati City, Northeastern India
Get PDFGround motion parameters for Shillong–Mikir Plateau of Northeastern India are examined. Empirical
relations are obtained for ground motions as a function of earthquake magnitude, fault type, source
depth, velocity characterization of medium and distance. Correlation between ground motion
parameters and characteristics of seismogenic zones are established. Simultaneously, new empirical
relations are derived for attenuation of ground motion amplitudes. Correlation coefficients of the
attenuation relations depend on the site classifications that are identified based on average shear
wave velocity and site response factors. The attenuation relation estimated for logarithmic width of
Mikir Plateau found to be a little bit higher than that of Shillong Plateau both for soft and hard groun
