Abstract:
The modes of action of the five major endo-(1→4)-beta-D-glucanases (I, II, III, IV and V) purified from Penicillium pinophilum cellulase were compared by h.p.l.c. analysis, with normal, 1-3H-labelled and reduced cello-oligosaccharides and 4-methylumbelliferyl glycosides as substrates. Significant differences were observed in the preferred site of cleavage even when substrates with the same number of glycosidic bonds were compared. Thus, although endoglucanase I was unable to attack normal cello-oligosaccharides shorter than degree of polymerization 6, it hydrolysed reduced cellopentaose to yie

Abstract:
Reaction at room temperature of either 3,4,6-tri-O-acetyl-2-azido-2-deoxy-α- or -β-D-galactopyranosyl chloride with a twofold excess of 4-methylumbelliferone and silver trifluoromethanesulfonate in dichloromethane containing an equimolar amount of.sym-collidine yielded 4-methylumbelliferyl tri-O-acetyl-2-azido-2-deoxy-α-D-galactopyranoside in 33% yield. The β anomer was formed in 20 and 10% yields, respectively. Reduction of the azido group, acetylation followed by de-O-acetylation, provided the desired 4-methylumbelliferyl 2-acetamido-2-deoxy-α- and -β-D-galactopyranosides (N-acetyl-α- and -β

Abstract:
4-Methylumbelliferyl beta-N-acetylglucosaminide 6-sulphate was purified from a mixture containing its unsulphated precursor. The substrate was used to test for the presence of functional alpha-subunits in ‘intermediate’ forms of human beta-N-acetylhexosaminidase in samples of normal and pregnancy serum and in extracts of placenta and lymphocytes from a patient with common acute lymphoblastic leukaemia. Intermediate forms in these samples had no activity towards 4-methylumbelliferyl beta-N-acetylglucosaminide 6-sulphate, indicating that they lack alpha-subunits.

Abstract:
abstract: The need for rapid, specific and sensitive assays that provide a detection of bacterial indicators are important for monitoring water quality. Rapid detection using biosensor is a novel approach for microbiological testing applications. Besides, validation of rapid methods is an obstacle in adoption of such new bio-sensing technologies. In this study, the strategy developed is based on using the compound 4-methylumbelliferyl glucuronide (MUG), which is hydrolyzed rapidly by the action of E. coli β-D-glucuronidase (GUD) enzyme to yield a fluorogenic product that can be quantified a

Abstract:
There is an increasing problem in getting quality water for developing countries. Water system is contaminated and without proper treatment, it has been consumed as drinking water. It is a big problem for health. Escherichia coli (E.coli) is the main cause for the contamination of water and illness in people. Early detection of E.coli presence in the drinking water followed by subsequent treatment for elimination of E.coli can solve this problem. The present work developed a new method for detecting E.coli in contaminated water using microspot with integrated wells (MSIW). The method involves
