Members of the genus LactobacilZus were examined for their ability to synthesize extracellular polysaccharide from sucrose. Strains physiologically similar to L. pastorianus synthesized a glucan. Other strains liberated a complex polysaccharide which contained mannose and glucose. Variants of the glucan-producing strains occurred spontaneously and these lacked the capacity to synthesize glucan ...
Production of ?-glucan is mainly used for cancer therapy. The most well-known are those occur in fungal grains such as cereal and other micro-organisms. The most important beta glucan from a nutritional and ingredient standpoint is that derived from fungal grain. Optimization of medium ingredients for the production of mycelial ?-glucan from lower fungi in submerged fermentation and antioxidant...
Two strains (15.1 and 15.8) of the thermophilic fungus Scytalidium thermophilum produced high levels of intracellular glucoamylases, with potential for industrial applications. The isoform I of the glucoamylase produced by 15.1 strain was sequentially submitted to DEAE-Cellulose and CM-Cellulose chromatography, and purified 141-fold, with 5.45% recovery. The glucoamylase of strain 15.8 was puri...
This was a placebo-controlled, double-blind study designed to evaluate the effect of a commercially available dietary supplement on upper-respiratory tract symptoms (URTI) and mood state. Seventy-five marathon runners (35 men, 40 women) ranging in age from 18-53 years, mean age: 36 ± 9, self-administered placebo, 250 mg or 500 mg of BETA 1,3/1,6 GLUCAN (commercial name Wellmune WGP(®)) daily du...
A major challenge to economically produce ethanol from lignocellulosic biomass is to achieve industrially relevant ethanol titers (>50 g L) to control operating and capital costs for downstream ethanol operations while maintaining high ethanol yields. However, due to reduced fermentation effectiveness at high biomass solids loadings, excessive amounts of enzymes are typically required to obtain...
conclusions while bdg assay seems to be a sensitive and specific adjunctive tool to diagnose and monitor the experimental systemic candidiasis, it seems that measuring the positive cutoff value in different laboratory conditions is necessary for favorable establishment of these tests. results all the infected rats were positive with bdg tests. an increasing level of bdg was observed during earl...
Periplasmic and extracellular glucans of Mesorhizobium huakuii were isolated and characterized by compositional and MALDI-TOF analyses, as well as H and C NMR spectroscopy. It was shown that M. huakuii produces a cyclic -glucan composed entirely of nonbranched glucose chains and unmodified by nonsugar substituents. The degree of polymerisation of the cyclic oligosaccharides was estimated to be ...
The isothermal phase behaviour at 5 °C of mixtures of sodium caseinate and oat β-glucan isolates varying in molecular weight (MW) was investigated by means of phase diagram construction, rheometry, fluorescence microscopy and electrophoresis. Phase diagrams indicated that the compatibility of the β-glucan/sodium caseinate system increases as β-glucan MW decreases. Images of mixtures taken at va...
A water-insoluble chitin-glucan complex, isolated from the mycelium of Aspergillus niger, was swollen in various aqueous media and treated subsequently by high-energy sonication. The concentration of the resulting water-soluble polysaccharide fractions was dependent on the swelling medium, the amount of the chitin-glucan complex in the suspension, and on the time of sonication. The yields of wa...
OBJECTIVES To evaluate the monthly variation in the airborne (1→3)-β-D-glucan level throughout one year and its relationship with climatic factors (temperature, relative humidity, wind speed, hours of daylight, cloud cover, and pollen counts). METHODS A total of 106 samples were collected using a two-stage cyclone sampler at five outdoor sampling locations (on top of 5 university buildings). ...
