Determinacion de hierro en fase solida por espectrofotometria derivada de segundo orden
(Sociedad Chilena de Quimica, 2001)
A microdetermination of iron at sub-μg/L level by derivative spectrophotometry has been developed. The compound TPTZ (2, 4, 6-tripyridyl-1, 3, 5-triazine) was used as chromogenic reagent to form a blue complex (pH = 5. 0), ...

Purification and characterization of xylanases from Aspergillus giganteus
(2004-04-20)
A strain of Aspergillus giganteus cultivated in a medium with xylan produced two xylanases (xylanase I and II) which were purified to homogeneity. Their molar mass, estimated by SDS-PAGE, were 21 and 24 kDa, respectively. ...
