To learn more about the role β-galactosidase plays in rate of
acid production in milk by lactic acid bacteria, several lactobacilli
were examined for this enzyme. Cells from different species were
grown in lactose broth to induce β-galactosidase activity. The specific
activities of whole, solvent treated cells, and of cell-free...
Purpose of the Study
The education of culturally diverse children has been one of the
focuses of education since the early 1960's. One of the factors
influencing education's inability to deal with the needs of culturally
diverse children is the lack of teacher's foundational knowledge of
language and linguistics as...
Polygalacturonase produced by Fusarium oxysporum f. sp.
lycopersici was purified by chromatography on DEAE cellulose, CM
cellulose, and hydroxylapatite. Removal of large amounts of carbohydrate
by chromatography on hydroxylapatite did not affect heat
stability of the enzyme. A large proportion of the remaining carbohydrate
appeared to be covalently linked to...
The culture of the green alga Botryococcus braunii Kutz. obtained
for use in this study was contaminated with bacteria and fungi. Algal
colonies from this culture sonicated, rinsed and treated with penicillin
(500 μg/ml), gentamicin sulfate (50 μg/ml) and amphotericin B
(5 μg/ml) were found to be axenic when incubated...
The structure of nickel dichloride in the vapor at ca. 1050 K has been studied experimentally by electron diffraction and theoretically by ab initio and DFT molecular orbital calculations. The molecule is found to have a linear equilibrium structure, and from all levels of theory it is predicted to have...
The correlation between dimensionless shear ϕₘ and dimensionless height z/L, where L is the Obukhov length, for stable conditions is strongly influenced by self‐correlation for the present datasets. This effect is quite large for stronger stability but still significant for near‐neutral conditions. A conditional analysis of nocturnal stable boundary‐layer data,...
