Background: Glyphosate (N-phosphonomethyl Glycine) is an organophosphorus pesticide with dangerous effects on the environment. In this study, the biodegradation of glyphosate herbicide by halophilic bacteria isolated from Qom Hoze-Soltan Lake has been investigated. Methods: After sampling and bacterial isolation, native halophilic strains grown in the presence of glyphosate at a wavelength of 6...

Bioleaching is the extraction of metals from their ores through the use of microorganisms. Inthis process, the use of native bacteria leads to achieve more yields of metals. So, in the presentstudy, native sulfur-oxidizing bacterium in potentiality of uranium extraction was isolated fromGhachin mine in Iran and identified by partial gene sequencing. For this purpose, the watersamples were colle...
Background: Lactic acid bacteria interfere to improve the taste of food products and and to prevent the growth of food spoilage organisms and pathogens with producing antimicrobial substances called bacteriocin. To study the antagonistic effect of isolated Lactobacillus from soil where native yogurt is processed against pathogenic bacteria is the purpose of this study. Methods: In this cross-s...

Cutin is a polymer that is constructed in plants by the condensation and oxidation of fatty acids and plays a key role in the protection of plants against pathogens. Cutinase is a hydrolase enzyme that breaks down the cutin. The purpose of this study was to extract cutin from red apples with oxalate buffer, cutinase enzyme activity assay in LB culture, and bioinformatic analysis. To attain thes...
background: during the last two decades, significant advances have been made in the fields of lactococcal genetics and protein expression. lactococcus lactis (l. lactis) is an effective vector for protein expression and can be used as an antigen delivery system. hence, l. lactis is an ideal candidate for mucosal immunotherapy. profilin (che a 2), the major allergen in chenopodium album, is one ...
abstract i the purpose of this study was to launch a thorough investigation concerning the possibility of differing orientations to the writing proficiency construct by native and non-native english speaking teacher raters. it mainly revolved around the international english language testing system (ielts) that is widely administered and employed as a measure of general proficiency in englis...
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
