Film dosage forms containing metronidazole (MZ) were prepared from natural polysaccharides, such as pullulan (PUL) or sodium alginate (ALG), without heating or controlling the pH. The release profiles of MZ from the films were investigated. In the absence of a drug, the casting method resulted in the polysaccharide forming a circular film, and the presence of MZ affected film formation. The thi...

Using media with low water activity, a large numbers of aureobasidium-like black yeasts were isolated from glacial and subglacial ice of three polythermal glaciers from the coastal Arctic environment of Kongsfjorden (Svalbard, Spitsbergen), as well as from adjacent sea water, sea ice and glacial meltwaters. To characterise the genetic variability of Aureobasidium pullulans strains originating f...

INTRODUCTION Size-exclusion chromatography is used in carbohydrate research to determine molecular weight distributions of polysaccharides. A variety of detection methods have been used, among them viscometry, lowangle laser light scattering (LALLS), refractive index, ultraviolet/visible absorbance, fluorescence, and precision differential refractometry coupled with ultraviolet detection.This a...

The gene encoding a type I pullulanase was identified from the genome sequence of the anaerobic thermoalkaliphilic bacterium Anaerobranca gottschalkii. In addition, the homologous gene was isolated from a gene library of Anaerobranca horikoshii and sequenced. The proteins encoded by these two genes showed 39% amino acid sequence identity to the pullulanases from the thermophilic anaerobic bacte...
