Background: Populations of Magnaporthe, the causal agent of rice blast disease, are pathotypically and genetically diverse and therefore their interaction with different rice cultivars and also antagonistic microorganisms are very complicated. Objectives: The objectives of the present study were to characterize phylogenetic relationships of 114 native Magnaporthe strains, isolated from rice a...
in this study, urease production was investigated among thirteen strains of aspergillus niger seven strains isolated from soils of semnan province in iran and six strains obtained from persian type culture collection (ptcc). the enzyme production was screened in two submerged media quantitatively. the registered ptcc 5011 and the native s31 strains showed more urease production than the other e...
This study aimed at applying both growth and survival approaches to compare three native strains of lactobacilli, belonging to Lactobacillus plantarum, Lactobacillus rhamnosus and Lactobacillus acidophilus species, with two commercial probiotic strains in their tolerance to acid and bile. The association between the data obtained from the methods was studied. The results of the different metho...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...

bacteriorhodopsin operates as a light/proton transfer pump which converts the light energy into a proton gradient. energy stored in the proton gradient can be used in a variety of ways. bacteriorhodopsin producing sources are some halobacterium species such as halobacterium sodomense and halobacterium salinarum which continue to grow in harsh and salt-saturated conditions. two types of red pigm...
this thesis aims to adduce an unmitigated and comprehensive explication concerning the relationship of three significant elements of fiction: setting, chracter and theme. my research is basically placed on two outstanding novels of the 19th century: emily brontes wuthering heights and thomas hardys return of the native. my endeavour lies in studying the correlation among the three above-mention...

since esp received universal attention to smooth the path for academic studies and productions, a great deal of research and studies have been directed towards this area. swales’ (1990) model of ra introduction move analysis has served a pioneering role of guiding many relevant studies and has proven to be productive in terms of helpful guidelines that are the outcome of voluminous productions ...
Prolactin, an important polypeptide hormone, is secreted by specialized cells in the anterior pituitary gland and is predominantly under inhibitory influence of the hypothalamus. This hormone plays a crucial role in incubation signaling and egg production in avian. The aim of this study was to determine the polymorphisms at situation +2402 bp (PRL5) and a 24-bp nucleotide in/del at nucleot...
