BACKGROUND Invertase Suc2 was recently identified as a key hydrolase for inulin catabolism in Saccharomyces cerevisiae, whereas the Suc2 activity degrading inulin varies greatly in different S. cerevisiae strains. The molecular mechanism causing such variation remained obscure. The aim of this study is to investigate how Suc2 activity is regulated in S. cerevisiae. RESULTS The effect of SUC2 ...

Inulin, a prebiotic, is a fermentable oligosaccharide that may affect the intestinal mucosal architecture and the electrophysiological parameters. The effects of a diet with added inulin were tested on the jejunal morphology and electrogenic transport of Glc and Gln from the jejunal mucosa in broilers. Short-circuit current and transmucosal tissue resistance of jejunal flaps were measured in Us...

Influenza virosomes are reconstituted influenza virus envelopes that may be used as vaccines or as carrier systems for cellular delivery of therapeutic molecules. Here we present a procedure to generate influenza virosomes as a stable dry-powder formulation by freeze-drying (lyophilization) using an amorphous inulin matrix as a stabilizer. In the presence of inulin the structural integrity and ...

Inulin consists of linear chains of β-2,1-linked D-fructofuranose molecules terminated by a glucose residue through a sucrose-type linkage at the reducing end. In this review article, inulin and its applications in bioprocesses are overviewed. The tubers of many plants, such as Jerusalem artichoke, chicory, dahlia, and yacon contain a large amount of inulin. Inulin can be actively hydrolyzed by...

It is believed that rare earth elements are not absorbed, and thus they are generally used in some mineral absorption studies as a faecal marker. The aim of the present study was to determine the effect of inulin intake and age on dysprosium (Dy) absorption in rats. Eighty male Wistar rats of four different ages (2, 5, 10 and 20 months) were randomised into either a control group or a group rec...

Fifty newborn Saanen kids were used to study the effects of inulin supplementation on faecal score, faecal pH, selected faecal bacterial population, BW, body temperature, haematological traits, selected health parameters and the incidence of diarrhoea. Kids were sorted by parity of their dams and multiple birth (twin or triplet) and assigned to one of the two groups (control: CG, and experiment...

Inulin, a linear β-fructan, is present in a variety of plants, with relatively high levels of up to 20% in chicory root. It exhibits prebiotic properties and was shown to enhance mineral absorption. Our objectives were to assess the effect of intra-amniotic administration of inulin at 17 d of incubation on the iron status of broiler chicks (at hatch, 21 d) and to continue to monitor iron status...

OBJECTIVE To improve the efficacy of intratympanic therapy using perilymphatic entry through the round window membrane. MATERIAL AND METHODS The perilymphatic entry characteristics of 2 neutral molecules, mannitol (182.2 Da) and inulin (7,000 Da), were studied. A polyethylene catheter was placed in contact with the guinea pig round window membrane and sealed with cyanoacrylate glue. This cath...

In this study, blueberry essential oil as a core material was microencapsulated with Inulin and β-cyclodextrin at a ratio of 1:5 (core: wall). Oil in water nano-emulsions were prepared by ultrasonic liquid processors and then transformed to encapsulate powder in spray dryer. Dried powder was stored at 4 ˚C in refrigerator for determining moisture, encapsulation efficiency and morphology prop...
