“…We could not confirm why CWPS carbohydrates contents differed when extracted by either the hot buffer or DMSO extraction methods. It has been reported that the Gal and Glc contents of the polysaccharides in the cell walls of wheat were reduced after autoclaving (Branton et al, 1996). Moreover, GXM is typically extracted after heat killing C. neoformans, whereas GalXM and GXMGal can be extracted without heating (Klutts and Doering, 2008;Heiss et al, 2009).…”

Trichosporon asahii is a pathogenic basidiomycetous yeast. Individual strains of T. asahii have different colony morphologies. However, it is not clear whether cell surface phenotypes differ among the colony morphologies. Here we characterized the cell surface hydrophobicity and analysed the carbohydrate contents of the cell surface polysaccharides in T. asahii clinical isolates with various colony morphologies. Among the three distinctive colony morphologies obtained from one clinical isolate, the white-type morphology exhibited higher hydrophobicity. The hydrophobicity of heat-killed T. asahii cells was greatly reduced after periodate oxidation of the cell surface carbohydrates. Furthermore, the cell wall and extracellular polysaccharide components differed among the morphologies. Our results suggest that T. asahii cell surface hydrophobicity is affected by cell surface carbohydrate composition. Copyright © 2016 John Wiley & Sons, Ltd.

“…Branton et al (1996), on the other hand, concluded that C. perfringens growth in TG was suppressed by the addition of wheat extracts compared with deionized water. These differing findings may be explained by the fact that three complete broiler grower diets, with a main constituent of wheat, barley or corn, were used in the present study, compared with a wheat extract alone used by Branton et al (1996). In addition, samples used by Branton et al were heated to 100°C for 24 h prior to adding them to culture media, a process that may have altered the endogenous enzymatic activity in the wheat extract.…”

Necrotic enteritis: Effect of barley, wheat and corn diets on proliferation of Clostridium perfringens type A

Necrotic enteritis, caused by Clostridium perfringens type A, is more prevalent in broilers fed wheat or barley diets than in those fed a corn diet. We compared the effects of wheat, barley and corn diets on in vitro proliferation of C. perfringens type A. Bacteria were inoculated into the supernatants delivered from either digested or non-digested barley, wheat and corn diets mixed with thioglycollate medium (1:3). Colony forming units were counted following incubation for 6 h at 40°C. There were no significant differences in clostridial proliferation among non-digested diets. Bacterial proliferation in the digested wheat and barley diets was significantly higher than in the digested corn diet. These findings suggest that the increased incidence of necrotic enteritis in broilers fed barley and wheat diets compared with those fed a corn diet may be due in part to increased clostridial proliferation associated with the wheat and barley diets, or to decreased proliferation associated with the corn diet.

“…We demonstrated that IDF has a greater adsorption capacity than SDF. By autoclaving, the contents such as barley or wheat, amino acids and glycosyl components have been changed (35,36). Similarly, the structure of IDF might have been changed by autoclaving.…”

Summary By autoclaving, we obtained a polyphenol and dietary fiber from pea (Pisum sativum L.) pods in parallel without acid or alkali treatment or organic solvent extraction. Rats fed a high-sucrose (HS) diet containing 3% autoclaved extract (AE) for 4 wk exhibited significantly lower serum triglyceride and total cholesterol levels than rats fed a HS diet. AE and soluble dietary fiber (SDF) from AE exhibited pancreatic lipase inhibitory activity at 13.3 mg/mL in vitro. AE and insoluble dietary fiber (IDF) from AE adsorbed cholesterol. In total, 30% and 10% of a cholesterol micelle were significantly adsorbed by 2,000 mg of AE and 100 mg of IDF from AE in 7 mL, respectively. The amount of bifidobacteria in the cecum of the AE group was significantly increased compared with that in the HS group. These results suggest that AE has hypolipidemic, bifidogenic potential.
