Recently, colonic health has been linked to the maintaining overall health status and reducing the risk of diseases by changes in lifestyle. Functional foods, such as "prebiotics" and "probiotics", dietary fibers, and other dietary components that target the colon and affect its environment enhancing short fatty acid (SCFA) production have been at the forefront. The topic of this review is the ...

Inoculation of maize silage with Lactobacillus buchneri (5 x 10(5) c.f.u. g(-1) of maize silage) prior to ensiling results in the formation of aerobically stable silage. After 9 months, lactic acid bacterium counts are approximately 10(10) c.f.u. g(-1) in these treated silages. An important subpopulation (5.9 x 10(7) c.f.u. g(-1)) is able to degrade 1,2-propanediol, a fermentation product of L....

A new method for rapid sampling and qualitative characterization of the headspace gases of closed in vitro cultures using solid phase microextraction (SPME) was evaluated for ruminal fluid and ruminal fluid with feed containing a feed additive. Gas sample collection was achieved by exposing a DVB/Carboxen/PDMS 50/30 m SPME fiber to the headspace of cultures for 1 min every hour. This was follow...

Three strains of anaerobic, pleomorphic, Gram-positive-staining bacilli, which were isolated from human carious dentine, were subjected to a comprehensive range of phenotypic and genotypic tests and were found to comprise a homogeneous group. The strains were saccharolytic and produced acetic and propionic acids in large amounts, and succinic acid in moderate amounts, as the end products of fer...

We investigated the distribution of short chain fatty acids (SCFA) in enema samples taken from subjects before sigmoidoscopy as an indicator of possible microbial community differences between subjects subsequently diagnosed as normal or having colonic disorders. The major SCFA in all groups were acetic, propionic, and butyric acids. A significantly higher ratio of acetate to total SCFA and low...

The article discusses the influence of starter cultures on quality meat for semi-smoked sausages. Attractive attention to biologically active, organoleptic and physic-chemical results includes fermented beef produce a finished product. use significantly affects tenderness, juiciness, nutritional value raw materials, formation required level structure adhesive ability, improves characteristics d...

6-Hydroxynicotinic acid was demonstrated to be the first intermediate in the degradation of nicotinic acid by a clostridium. In the presence of pyruvate, other intermediates accumulated; two of these were identified, one as 1,4,5,6tetrahydro-6-oxonicotinic acid, and the other as a!-methyleneglutaric acid. The pathways for nicotinic acid degradation may be considered as involving successive oxid...

The basic parapharmaceuticals in the Polish diet include natural anti-oxidants bioflavonoids found in berry fruit. They were proven to have the ability to regulate genetic transcription and increase the synthesis of nitric oxide which counteracts dysfunction of the vascular endothelium. They also display anti-oxidant action through the inhibiting effect on cyclooxygenase COX-2, and increase the...

This study explores the production of prebiotic xylooligosaccharide (XOS) from cassava pulp waste and its effectiveness for growth Lactobacillus acidophilus (L. acidophilus). We successfully produced characterized XOS xylan using a Bacillus sp. endo-β-1,4-D-xylanase. The was added to modify MRS medium (MRSm) in various concentrations (0, 1, 3 5%) which L. inoculated. observed every 12 h 2 days,...

Fermentation processes in the rumen of ruminants determine how much final metabolites and their derivatives will be formed, which are necessary for full development organism, level productivity, also affect formation endogenous substances, namely, greenhouse gas emissions. These criteria lead us to search new feed products that improve metabolic digestive system as a whole, so phyto-substances ...
