Volatile fatty acids are reported to exert a repressive effect upon Enterobacteriaceae and Pseudomonas species in vitro and in vivo in young mice. The mean total volatile fatty acid concentration in the cecal samples of conventional mice fed ad libitum was 81.7 mumol/g (wet weight), which is antibacterial in vitro, and in the rectal samples it was 41.1 mumol/g (wet weight). The mean count of En...

Background Background: The fatty acid composition of the sperm membrane changes drastically during spermatogenesis and may be key to its function. Previous data has shown that intake of long chain poly-unsaturated fatty acids can change the fatty acid composition of tissues, including testes and sperm. However, whether these changes in composition translate into changes in semen quality or male...

background: the high percentage of consumed antibiotics by humans and animals is excreted with other residues from the body after its performance. by entering these compounds to the wastewater, they can disrupt the anaerobic treatment process. in this study, deterrent behavior of two ampicillin and gentamicin antibiotics are investigated on specific methanogenic activity (sma) of anaerobic biom...

changes in the fatty acid composition and biochemical indices of mackerel (which has a substantial lipid content) and shark (which has negligible lipid content) fillets stored at - 18°c for up to six months were measured. lipid content was measured (6.35% and 1.38%) in mackerel and shark, respectively; however it decreased during frozen storage in both fish species. in analysis of fatty acids t...

A total of 48 different volatile oils were identified form P. brevitarsis larvae by gas chromatography/mass spectrometry (GC/MS). Acids (48.67%) were detected as the major group in P. brevitarsis larvae comprising the largest proportion of the volatile compounds, followed by esters (19.84%), hydrocarbons (18.90%), alcohols (8.37%), miscellaneous (1.71%), aldehydes (1.35%) and terpenes (1.16%). ...

The aim of the investigation was to determine the changes in fatty acids profile and chemical quality indexes of Red Tilapia fillets during frozen storage at -18°C. The fish were filleted by hand. The prepared fillets were then placed to the polyamide pouches and stored at -18°C for 150 days. Fatty acid profile, sensory properties and chemical quality indices were determined for a five month pe...

Brassica napus L. and Sinapis alba L. are two cruciferous species for which some medicinal uses are mentioned in the Iranian, Indian and Chinese traditional medicine. Seed oil of  B. napus has cathartic action, and is either used as such or after partial hydrogenation for cooking, shortening or as margarines. Sees of S. alba have also cathartic action and some other medicinal uses but, beca...

Two experiments (Exp.) were conducted to determine the effects of dietary addition of five herbal plants (HP) alone or as herbal plant mixture (HPM) on in vitro gas production and ruminal fermentation patterns. In Exp. 1, five varieties of HP (garlic, eucalyptus, cinnamon, thyme, and peppermint) were added to the diet at 3 different concentrations (5, 10 and 15% of concentrate dry matt...
