Carvacrol and thymol in combination at 6.7 mM each completely inhibited the production of short-chain volatile fatty acids and lactate from cattle waste in anoxic flasks over 23 days. Fecal coliforms were reduced from 4.6 x 10(6) to 2.0 x 10(3) cells per ml 2 days after treatment and were nondetectable within 4 days. Total anaerobic bacteria were reduced from 8.4 x 10(10) to 1.5 x 10(7) cells p...

Abstract Objective Beehive air therapy is recognized as a potential remedy for treating asthma, bronchitis, lung fibrosis, and respiratory tract infections. Developed countries in which beehive currently authorized include Germany, Hungary, Slovenia, Austria. However, scientific proof of its efficacy lacking warrants further chemical biological analyses concept. In this study, volatile profile ...

Effect of different concentrations hypotaurine (HTU) on melanosis and quality shrimps during 10 d storage in ice were studied. During refrigeration, the total plate count volatile basic nitrogen treated with 20 g/L HTU lowest, hardness microstructure best. Moreover, score melanoses, pH bile acid also low. Sensory evaluation showed that treatment could make shelf life 3-4 days longer compared co...

'Early Rich', 'Royal Glory', 'Sweet Dream(cov)', and 'Elegant Lady' peaches were stored at -0.5 °C for up to 40 days and then subjected to ripening at 20 °C for up to 3 days. Firmness, soluble solids content (SSC), titratable acidity (TA), color, consumer acceptance, and volatile compounds were then determined. The observed physicochemical changes included a significant decrease in firmness dur...

The synergism of food waste associated with swine manure can provide an increase in biogas production, besides promoting greater stability the anaerobic co-digestion process. To verify this effect, tests were performed two reactors, one agitation, and other without agitation. In both systems, gasometers used to measure production experiment lasting hydraulic retention times (HRT). On each feedi...

One quorum sensing strain was isolated from spoiled turbot. The species was determined by 16S rRNA gene analysis and classical tests, named Aeromonas sobria AS7. Quorum-sensing (QS) signals (N-acyl homoserine lactones (AHLs)) were detected by report strains and their structures were further determined by GC-MS. The activity changes of AHLs on strain growth stage as well as the influence of diff...

UNLABELLED An assessment on quality and hygienic conditions of spring water was undertaken in Mongolia in 2004 with financial and technical support from the World Health Organization through AGFUND. METHODOLOGY A total of 127 springs, 99 from rural areas and 28 from Ulaanbaatar city were included in the study. The study included hygienic conditions, physical, microbiological and chemical para...

In this study, it was aimed to investigate that the effect of drying process on rainbow trout (Oncorhynchus mykiss Walbaum, 1792) roes in terms proximate composition, aw, pH, TVB-N, TBARs, microbiological counts and color parameters. Drying lasted 42 hours including, 18 at 30oC 24 45oC. The dried fish were vacuum-packed (vacuum degree 0.02MPa) stored 4oC for 90th days. crude lipid, protein, ash...
