Tests were carried out with the aim to bind polygalacturonase to carboxy-, alkylo- and aryloamine derivatives of porous glass. The in: fluence of the type of carrier surface on the quantity and activity of the immobilized enzyme and the role of substrate in the process of enzyme binding were examined.
The trials for the continuous process of hydrolysis of pectic substrates with the use of polygalacturonase immobilized on a porous glass, were carried out. The reactors of different types were applied and small changes in viscosity of substrates in spite of highly active immobilized enzymes usage, were observed. The mechanism of pectin hydrolysis by the immobilized enzyme was discused.
The chloroplastic fraction of green alfalfa juice was separated by centrifugation, heating the juice to 333°K, or application of the polyelectrolytes Magnafloc L T-27 and M-22S. The cytoplasmatic fraction was precipitated by beat (358°K) or acid coagulation (pH = 3.5). The supematants after chloro- and cytoplasmatic fraction separation (chloroplast free juice and whey) were chromatographed on a Sephadex G-100 column.
This study was conducted to compare of the yeasts identification results obtained with two new systems using the MALDI-TOF MS technique with the ones obtained using the routine identification methods of Candida spp. in clinical microbiology laboratories. All 124 Candida spp. isolates were recovered from the routine examination of clinical specimens in microbiological laboratories and collected in the Centre of Quality Control in Microbiology in Warsaw (Poland). Our findings confirm the high agreement (98%) of fungal identification using the standard, biochemistry laboratory methods and mass spectrometry technique.
Four Klebsiella pneumoniae isolates from children hospitalized over 10 months in an intensive care unit in a children’s teaching hospital in Poland were analyzed. All of the isolates belonged to a single pulsotype and sequence type (ST) 11, and produced the KPC-2 carbapenemase and extended-spectrum β-lactamase (ESBL) CTX-M-15. They were resistant to a variety of antimicrobials, and their β-lactam resistance patterns were typical for KPC producers. This is one of few cases of identification of KPC (or carbapenemase)-producing K. pneumoniae in a pediatric center in Poland.
