background and objectives: thermophilic bacteria are less studied but important group of microorganisms due to their ability to produce industrial enzymes. materials and methods: in this study, thermophilic bacteria were isolated from hot spring of tarabalo, india. a bacterium that could tolerate high temperatures was characterized by morphology, biochemistry and sequencing of its 16s rrna gene...
among the 30 strains of moderately halophilic bacteria isolated from the salty effluents of textile industries around qom city in central iran, a gram-negative rod shape bacterium designated as strain ip8 showed a remarkable ability in decolorizing of azo dyes over wide ranges of ph (7-11) and temperature (25-45 ºc), in presence of nacl and na2so4 (0.5-1.5 m) under anaerobic and aerobic conditi...
Contamination sites of Pseudomonas fluorescenswere traced in the production line for milk pasteurization in a large dairy plant in Shiraz, Iran. Samples of raw and pasteurized milk were collected at six sites along the line. All milk samples were incubated at 7°C until the aerobic plate count had reached 10 6 -10 7 cfu mL-1. Colonies were picked randomly and identified. No growth of gram negati...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
barley belongs to the poaceae which is the largest monocotyledon family. plastid single-copy gene acetyl-coa carboxylase (accase) is the first step in the biosynthesis of fatty acids and therefore, it is used to study the phylogenetic relationships, evolutionary and systematic of grasses. in this study, for the first time, phylogenetic relationship of eight species of hordeum genus from iran in...
abstract this study aimed at investigating the translation of interjections from english into persian in dubbing. to carry out this study the expressive secondary interjections found in the film four weddings and a funeral and their equivalent in persian dubbed version were analyzed through the strategies proposed by cuenca. the descriptive analysis of the corpus showed that (strategy b) i.e...
background and aims: avian influenza (ai) h9n2 subtype was first reported to infect turkeys in the united states in 1966 and has been panzootic in europe and asia. the impact of avian influenza caused by h9n2 viruses in iran is now significantly more severe than in previous years. methods: sequence analysis and phylogenetic study of the complete coding region polymerase a (pa) gene of h9n2 subt...
asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
background and objectives: rapid clinical manifestation/progression of the meningococcal meningitis and lacunae in conventional bacteriological test often encourages indiscriminate use of antibiotics much before the etiology is established. this study was planned to evaluate ctra pcr for rapid molecular detection. in addition, multiplex pcr and sequencing was done for serogroup prediction to pr...
in this study, the cdna growth hormone (cgh) of the belugasturgeon (husohuso) and russian sturgeon (acipensergueldenstaedtii) were cloned and sequenced, and phylogenetic relationships were examined using nucleic acid and amino acid sequences. the nucleotide sequence of the beluga gh has an open reading frame of 645 nucleotides encoding a protein 214 amino acid residues. the signal peptide cleav...
