Copper oxide nanoparticles have many applications in industry and medicine. Nevertheless, few studies been conducted relation to the biological production of these nanoparticles. In present study, ability isolated Psychrotrophic (cold-resistant) prokaryotes from Zagros highlands located Lorestan province Iran some Streptomyces strains Oman Sea has evaluated synthesis copper The maximum lethal c...

The aim of the present study was to evaluate influence NaCl concentration on microflora in Kashkaval cheese produced from cow’s milk. Three samples were obtained - with low (0.7%), medium (1.5%), and standard (3.1%) content NaCl. Microbiological analyses performed 1st, 15 th , 30 45 d ripening. It established that has a significant (p < 0.05) growth activity studied samples. been observed to...

Lactoferrin is a glycoprotein with various biological effects, with antibacterial activity being one of the first effects reported. This glycoprotein suppresses bacterial growth through bacteriostatic or bactericidal action. It also stimulates the growth of certain kinds of bacteria such as lactic acid bacteria and bifidobacteria. In this study, Asn-Leu-Asn-Arg was selected and chemically synth...

the effects of essential oils (eos) of oregano and nutmeg with and without commercial emulsifier/stabilizer compound (e/s) on the microbial quality of ready-to-cook barbecued chicken were evaluated. barbecued chicken was traditionally prepared. 3 μl/g and 10 mg/g of eos and/or e/s were then added to the barbecued chicken, respectively. the samples were stored at 3°c for 144 h, 8 and 20ºc for 72...

This study was aimed to determine the microbial load and hygienic status of household refrigerator surfaces. Psychrotrophic coliform bacteria counts were carried out refrigerators. Surface samples investigated in 3 groups as housewives’, students’ workers’ refrigerators, each group, including ten A total two hundred forty samples, one twenty sides shelves taken from side shelf surfaces a thirty...

The microflora of raw milk is in the center constant attention at enterprises where it processed. Since microbiota pasteurized determined by percentage heat-resistant bacteria that are present material. Defects during storage associated with development residual products. aim work was to determine quantitative changes using different pasteurization temperatures. Pasteurization first and extra g...
