The thermophilic aldolase from Bacillus stearothermophilus
(NCA 2184) has been purified to a specific activity of 45.5 μ-moles
of fructose-1, 6-diphosphate cleaved per minute per mg of enzyme,
representing a 624-fold increase over the crude extract. The preparation appeared to be homogenous by sedimentation velocity ultra-centrifugation
and by a specific...
Perloline levels have been associated with poor animal
performance on tall fescue pastures. Animal performance is
low when perloline levels are high. High perloline levels
are reported during hot, dry weather and increased N
fertilization. Tall fescue perloline levels appear to be
affected by genetic and environmental differences. Positive
associations...
