The purpose of this study was to investigate the therapeutic effects of propolis on biochemical and microbiological parameters in muscle tissues of carp (Cyprinus carpio, Linnaeus 1758) exposed to arsenic. A sublethal concentration of arsenic (0.01 ppm) and/or 0.01 ppm propolis were administered to fish for seven days. Biochemical parameters [pH, lactic acid, total volatile basic nitrogen (TVB-...

Water from a continental high-temperature, long-term water-flooded petroleum reservoir in Huabei Oilfield in China was analysed for its bacterial community and diversity. The bacteria were characterized by their 16S rRNA genes. A 16S rRNA gene clone library was constructed from the community DNA, and using restriction fragment length polymorphism analysis, 337 randomly selected clones were clus...

in recent years, there has been an increasing interest in using food additives from natural sources to improve taste and also extend the shelf-life of semi-preserved foodstuffs. the aim of this study was to examine the chemical and microbiological changes promoted by a local marinating process in rainbow trout fillets during chilled storage. fish fillets were immersed in marinades and stored at...

The aim of this study was to evaluate microbiological contamination levels of indoor air in some farm settings, including barns and dairy objects. The level of microorganism emissions from farm buildings into atmospheric air was also estimated. In the research a MAS-100 air sampler (MERCK) was used. It was revealed that the number of microorganisms in barns ranged between 1.7·10 8.8·10 for meso...

 Cypermethrin is a potential toxic pollutant that directly threatens the aquatic ecosystems and environment. Propolis, a natural product collected from plants by honey bees has many functions, such as antimicrobial, antioxidant, and anti-inflammatory. This study attempted to detrmine some biochemical and microbiological parameters of rainbow trout fillets after exposure to propolis and cypermet...

The effects of ultraviolet (UV) radiation were investigated with regards to the microbial growth inhibitory effect on the shelf life of Korean native cattle (Hanwoo) beef prior to refrigerated storage. The Hanwoo samples were exposed to UV radiation (4.5 mW/cm(2)) for 0, 5, 10, 15, and 20 min. The UV-irradiated beef that was exposed for 20 min showed significantly reduced mesophilic and psychro...

The degree of inactivation by UV irradiation was different between vegetative cells and spores of bacteria isolated from sewage sludge composting at 60 degrees C. By using this property, a method to estimate the spore ratio of a mixture of vegetative cells and spores was presented. This UV irradiation method was applied to the estimation of the spore ratio of sewage sludge compost samples colle...

morphological, biochemical and molecular characteristics were studied to identify dominant lactic acid bacteria (lab), isolated from traditional yoghurts produced by tribes of iran. from 60 yoghurt samples, a total of 137 lab isolates were determined, in which 66 and 71 were identified as lactic acid cocci and bacilli, respectively. biochemical tests showed the occurrence of 9.76% mesophilic ho...
