the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
One of the most important virulence factors in Pseudomonas aeruginosa is biofilm formation, as it works a barrier for entering antibiotics into bacterial cell. Different environmental and nutritional conditions were used to optimize formation using microtitre plate assay by P. aeruginosa. The low nutrient level medium represented tryptic soy broth (TSB) was better than high with Luria Broth (LB...
In order to study the bacterial flora of dead-in-shell ostrich chicks, twelve unhatched eggs which did nothave external pipping during the hatching period were transferred to the laboratory of microbiology. The eggshells were accurately disinfected and the embryos were removed and placed in a sterile plate. The surface of each embryo was swabbed with a sterile swab which was also plunged throug...
Abstract Biogenic amines (BAs) are organic compounds found in fermented food products, such as sausage, vegetables, wine, and fish sauce. Due to their potential be harmful human health markers of quality, BAs content can used an indicator quality safety. Some bacteria have the ability produce or degrade during fermentation. Environmental conditions influence growth that biogenic amines. The aim...
Aim: Antibiotic resistance is a major health problem. Recently, probiotics are used in the field of alternative/supportive medicine. Thus, this study, we aimed to evaluate vitro inhibitory effects four different cell-free supernatants (CFSs) lactobacilli species (L. fermentum, L. plantarum, acidophilus and rhamnosus) on clinically isolated Methicilin-resistant Staphylococcus aureus (MRSA) strai...
An unknown mortality was occurred in some ponds of a farm in an area of Kohgiloyeh-&-Boyerahmad province. Three ponds showed the highest mortality rate, about 5 to 20 dead fish were reported daily for 45 days. Afflicted fish have darkening in the skin and swimming near surface or at the floor of pond and swam unmatched with flock. Some fish showed hemorrhages around and within the oral cavity a...
in this study, the relationship between teachers’ creative and critical thinking skills and their reflectivity in teaching was investigated. to this end, three questions were raised. these questions were intended to determine whether there was a significant relationship between teachers’ creative thinking skills and their reflectivity in teaching; whether there was a significant relationship be...
We studied the action of high pressure processing on the inactivation of two foodborne pathogens, Staphylococcus aureus ATCC 6538 and Salmonella enteritidis ATCC 13076, suspended in a culture medium and inoculated into caviar samples. The baroresistance of the two pathogens in a tryptic soy broth suspension at a concentration of 10(8)-10(9) colony-forming units/ml was tested for continuous and ...
tourism , today as one of the ways to make money, create jobs , and social and political interactions is considered. this paper aims to examine the strengths and weaknesses of tourism development in mahmoud abad ( mazandaran ). the research method in this study is " descriptive - analytical " and to collection of data used field methods such as questionnaires and documentation - library. the sa...
Sixteen Staphylococcus aureus isolates originating from foods (eight from dairy products, five from fish and fish products and three from meat and meat products) were evaluated regarding their biofilms formation ability. Six strains (E2, E6, E8, E10, E16, and E23) distinguished as strong biofilm formers, either in standard Tryptic Soy Broth or in Tryptic Soy Broth supplemented with 0.4% glucose...
