Simultaneous Optimization of Acetaldehyde and DMS Concentrations for Better Sensory Quality of Beer Fermented on an Industrial Scale.

The levels of selected volatile components that affected the sensory properties of a lager beer were optimized under high-gravity brewing conditions (15.5 °P) in an industrial plant. The influence of different pitching rates (6-10 million cells/mL), aeration levels (8-12 mg/L), times (4.

The Impact of Phytases on the Release of Bioactive Inositols, the Profile of Inositol Phosphates, and the Release of Selected Minerals in the Technology of Buckwheat Beer Production.

A relatively high concentration of phytate in buckwheat malt, and the low activity of endogenous buckwheat phytases, both of which limit the effective use of substrates (starch, proteins, minerals) for fermentation and yeast metabolism, gives rise to the potential for application of phytases in beer production. This study aims at obtaining a 100% buckwheat wort with high bioactive cyclitols (-inositol and D--inositol) concentrations released by exogenous phytases and acid phosphatases. Two mashing programs were used in the study, i.

Solid-State Fermentation Reduces Phytic Acid Level, Improves the Profile of Inositol Phosphates and Enhances the Availability of Selected Minerals in Flaxseed Oil Cake.

Flaxseed oil cake was subjected to fermentation with (DSM 1964 and ATCC 64063), and the phytate (InsP) content, inositol phosphate profile and bioavailability of essential minerals were studied. Flaxseed oil cake had a phytate mass fraction of 13.9 mg/g.

Phytase modulates ileal microbiota and enhances growth performance of the broiler chickens.

Phytase is well studied and explored, however, little is known about its effects on the microbial ecology of the gastrointestinal tract. In total, 400 one-day-old female Ross 308 chicks were randomly distributed to four experimental groups. The dietary treatments were arranged as a 2 × 2 complete factorial design, with the factors being adequate (PC) or insufficient calcium (Ca) and digestible phosphor (dP)(NC) and with or without 5000 phytase units (FTU)/kg of Escherichia coli 6-phytase.

Phytases Improve Inositol Bioaccessibility in Rye Bread: A Study Using an Method of Digestion and a Caco-2 Cell Culture Model.

Preparations of 6-phytase A (EC 3.1.3.

Prostaglandin E2 supports growth of chicken embryo intestinal organoids in Matrigel matrix.

Investigating intestinal physiology in vitro remains challenging due to the lack of an effective primary enterocyte culture system. Recently developed protocols for growing organoids containing crypts and villus from adult mouse intestinal epithelium in Matrigel present an attractive alternative to the classical techniques. However, these approaches require the use of sophisticated and expensive serum-free medium supplemented with epithelial growth factor (EGF), Wnt agonist (R-spondin 1), and bone morphogenetic protein inhibitor (Noggin) in high concentrations.

In vitro efficacies of phosphorolytic enzymes synthesized in mycelial cells of Aspergillus niger AbZ4 grown by a liquid surface fermentation.

Activities of phytase, a pH 6.0 optimum nonspecific phosphomonoesterase and phosphodiesterase assayed toward bis(p-nitrophenyl)phosphate (phosphodiesterase I) and against p-nitrophenylphosphorylcholine (phosphodiesterase II), were partially purified from mycelial extracts of Aspergillus niger AbZ4 cultivated on a molasses medium by a liquid surface fermentation method. After elimination of phosphate from the medium, 7.
