the purpose of this study is to investigate the relationships between teachers’ immediacy behaviors and iranian students’ willingness to talk in english classes. analysis of the results from willingness to talk scale represents a relatively high level of willingness to talk in english classrooms among iranian language learners. the total mean score of students’ willingness to talk was 66.3 ou...
abstract the aim of the present research was to isolate plant growth promoting rhizobacteria producing acc deaminase which was able to alleviate negative effects of salinity on plant growth. 21 composite soil samples and canola roots were collected from the saline and relatively saline soils of qom and qazvin provinces. 105 strains were selected from the soil rhizosphere of canola. according to...
ABSTRACT Background and Objectives: Biofilm is a population of bacteria growing on a surface and enclosed in an exopolysaccharides matrix, which increases resistance to antimicrobial agents and immune response. Uropathogenic Escherichia coli (UPEC) are biofilm-forming bacteria and the most common cause of urinary tract infections (UTIs). This study ev...
This study was performed to investigate the effects of antibiotic, organic acid, probiotic and prebiotic supplementation on performance, egg shell quality, pH value of gastrointestinal (GI) tract and small intestinal morphology of laying hens. The experiment was a completely randomized design with 160 laying hens strain (W-36) from 32 to 42 weeks of age, with five treatments, four replicates an...
Background: Antimicrobial and antioxidant properties of the essential oils (EOs) are important in food industry. This study investigated the effects of EO from Cuminum cyminum on the preservation of yogurt containing Streptococcus thermophilus, Lactobacillus bulgaricus, and Bifidobacterium bifidum. Methods: The yogurt samples’ biological, physicochemical, and sensorial characteristics were eval...
