The activity of invertase and its relation to growth were studied in the epicotyls of lentil seedlings incubated in the presence and absence of gibberellic acid (GA(3)).Invertase activity per epicotyl increases relatively more rapidly than does length, reaches a maximum during most active elongation, and declines upon cessation of growth.GA(3) enhances both growth and increase in invertase acti...
Portable biomimetic sensor devices for the express control of phenols content in water were developed. The synthetic binding sites mimicking active site of the enzyme tyrosinase were formed in the structure of free-standing molecularly imprinted polymer membranes. Molecularly imprinted polymer membranes with the catalytic activity were obtained by co-polymerization of the complex Cu(II)-catecho...
Phenacetin and lactose powders, as models of slightly and highly water-soluble drugs, respectively, were coated by means of the Wurster process. Phenacetin (80-250 mesh) was a fragile crystalline material and hence fluidization had to be moderate. As a result, the agglomeration of some particles or the adhesion of small particles to large particles could not be avoided. However, the particles c...
