IN the dairy industry moulds are often encountered on media containing lactic acid. According to the literature on the subject, the view appears to be justified that this acid is oxidized by the moulds into CO2 or transformed into oxalic acid. Wehmer [1929] reports that by the action of Aspergillus mutantus calcium lactate is transformed into carbonate and sodium lactate into oxalate. Similarly...

Obesity is one of the major health problems throughout the world. The present study investigated the preventive effect of epilactose--a rare non-digestible disaccharide--on obesity and metabolic disorders in mice fed high-fat (HF) diets. Feeding with HF diets increased body weight gain, fat pad weight and adipocyte size in mice (P<0·01), and these increases were effectively prevented by the use...

Although the composition of the mixture of volatile fatty acids in the rumen of the sheep may be determined, it can throw no light on the composition of the mixture actually formed in the fermentation unless the relative rates of absorption of the acids are known, for it has been established that they are readily absorbed through the rumen wall into the blood stream (Barcroft, McAnally & Philli...

In this research, it was aimed to determine some chemical, microbiological and sensory properties of acur pickles compare them with Turkish Standards their differences. Chemical analyzes were determined pH the pickle 3.27-3.99, salt 2.85-8.15%, titration acidity 0.51-0.97%, dry matter 4.80-8.35%, vitamin C 4.15-6.81 mg/100mL, lactic acid 0.229-0.530 mg/mL, acetic 0.137-0.256 propionic 0.027-0.0...

Effective and economical mycobactericidal disinfectants are needed to kill both Mycobacterium tuberculosis and non-M. tuberculosis mycobacteria. We found that acetic acid (vinegar) efficiently kills M. tuberculosis after 30 min of exposure to a 6% acetic acid solution. The activity is not due to pH alone, and propionic acid also appears to be bactericidal. M. bolletii and M. massiliense nontube...

Objective(s): This study aims to evaluate combined proton nuclear magnetic resonance (1H NMR) spectroscopy and gas chromatography-mass spectrometry (GC-MS) metabolic profiling approaches, for discriminating between mustard airway diseases (MADs) and healthy controls and for providing biochemical information on this disease. Materials and Methods: In the present study, analysis of serum samples ...

The formation of SCFA in rats fed fermented oat fibre concentrates was compared with that of rats fed native oat fibre concentrate. The cultures used were lactic acid bacteria consisting of Lactobacillus bulgaricus and Streptococcus thermophilus (V2), the exopolysaccharide-producing strain Pediococcus damnosus 2.6 (Pd) and L. reuteri (Lr). The materials were incorporated into test diets yieldin...

BACKGROUND The diagnosis of irritable bowel syndrome (IBS) relies on symptom-based criteria. A valid and reliable biomarker that could confirm the diagnosis is desirable. This study evaluated the properties of faecal short-chain fatty acids (SCFA) as diagnostic biomarkers for IBS. METHODS Twenty-five subjects with IBS and 25 controls were included in this explanatory case-control study. Stool...

We describe a procedure for preparing fecal samples for determination of volatile fatty acids (VFAs) by gas-liquid chromatography (GLC) and "high-performance" liquid chromatography (HPLC). The simple, one-step procedure involves only ultrafiltration through a membrane with a molecular-mass cutoff of 3000 Da. As revealed by the GLC chromatograms, ultrafiltration appears to be as effective as ste...
