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...
