abstract extensive application of atrazine and its toxicity in environmental has attracted researcher attention for finding new degradation methods to this organic pollutant. biodegradation is one of most effective methods for removing atrazine. due to the importance of atrazine herbicide as an organic pollutant, a design carried out at factorial experiment in completely randomized design with ...
Pseudomonas aeruginosa is an opportunistic bacterial pathogen that is widely occurring in the environment and is recognized for its capacity to form or join biofilms. The present review consolidates current knowledge on P. aeruginosa ecology and its implication in healthcare facilities premise plumbing. The adaptability of P. aeruginosa and its capacity to integrate the biofilm from the faucet ...
Background: Heavy metals enter the environment through industrial activities and contaminate natural ecosystems. Identification of heavy metal-resistant bacteria plays an important role in environmental pollution and ultimately cleansing it. Therefore, the aim of the present study was to isolate the resistant genes of Pseudomonas aeruginosa and the effects of nanoparticles on gene expression u...
Conventional leather processing involving depilation of animal hide by lime and sulphide treatment generates considerable amounts of chemical waste causing severe environmental pollution. Enzymatic depilation is an environmentally friendly process and has been considered to be a viable alternative to the chemical depilation process. We isolated an extracellular protease from Pseudomonas aerugin...
The resistance patterns of Pseudomonas aeruginosa strains isolated from freshwater and seawater to different antimicrobial agents and heavy metals were studied. It was found that resistance in these environments is linked to the level of faecal pollution. All strains were resistant to ampicillin and tetracycline but sensitive to carbenicillin, amikacin, tobramycin, and colistin, and to the assa...
Two bacterial strains were isolated from pharmaceutical effluents discharged soil. The samples were identified as Klebsiella pneumonia and Pseudomonas aeruginosa the biological degradation was carried on two bacterial isolates separately added to pharmaceutical effluent water. After proper interval were analysed the physic chemical parameters such as pH, Turbidity, Chemical oxygen demand (COD),...
Abstract Background and Objective: Cystic fibrosis (CF) is an autosomal recessive genetic disease and Pseudomonas aeruginosa is one of the most common bacteria colonized in CF patients. Growing resistance of this bacterium to antibiotics now a day is a challenge of controlling infection in CF patient. In this study colonization of CF patients with Pseudomonas aeruginosa and antibiotic suscep...
Background and Objective: Pseudomonas aeruginosa is a causative agent of nosocomial infections. Metallo-beta-lactamases (MBLs) are considered among the most crucial resistant agents of Pseudomonas aeruginosa to carbapenem. Because of the important role of carbapenemes in the treatment of Pseudomonas infections, in this study, the Pseudomonas aeruginosa producing metallo-beta-lactamases were inv...
Background & Objectives: Pseudomonas aeruginosa is a common cause of nosocomial infection. OprD protein is a specific protein regulating the uptake of carbapenem antibiotic. Loss of OprD is the main mechanism of Pseudomonas Aeruginosa resistance to carbapenem. In this study, the presence of OprD gene is investigated in isolated Pseudomonas Aeruginosa in burn patients of Ghotboddin hospital in S...
آلودگی آب های دریایی با هیدروکربن های پلی آروماتیک (pahs) سبب آسیب های جبران ناپذیری در جانداران از جمله تخریب بافت جگر و سلول های قرمز خون و همچنین انواع سرطان ها می شوند. وجود این ترکیبات در محیط، ناشی از سوخت ناقص ترکیبات آلی ، تخلیه پس ماندهای ناشی از پالایشگاههای نفت و یا در اثر نشت نفت از تاسیسات ساحلی و کشتی های نفت کش می باشد. یافتن روش های مناسب برای کاهش این ترکیبات در محیط زیست دریا ...
