Endosulfan is a lipophilic insecticide, which causes severe health issues due to its environmental stability, toxicity, and biological reservation in organisms. It found the atmosphere, soil, sediments, surface waters, rain, food almost equal proportions. The aim of this study was isolate identify endosulfan-degrading bacteria from Kor River evaluate possibility applying bioremediation reducing pollution desired region. Samples sediments water were collected three different stations two...

Abstract Chemical pesticides or insecticides with complex structures are highly abundant in the biosphere and have inevitable side effects on farmland, natural resources, human health. Deltamethrin is most popular widely used pesticide that disrupts cellular calcium channels. In present study, isolated strains of bacteria were examined to determine ones capable degrading deltamethrin. Different species evaluated terms capability degrade It important note Streptomyces rimosus was able up 200...

Phenol and its components are extremely toxic can easily be isolated from different industrial sewage such as oil refinery, petrochemical industry mines, especially collier chemical factories. Hence the presence of these compounds in environment could cause environmental pollution, water resources. In past, physicochemical method was used for elimination phenol compounds, but today, bioremediation is preferable. The aim this study to isolate identify degrading bacteria Lake Parishan assay...

Petroleum hydrocarbons are species of dangerous contaminants in nature. Scientists looking for many years to find solution removing from the soil and water environments. Today, use microorganism, crude oil pollution contaminated sites (bioremediation) is considered by scientists. The purpose this research isolate identify degrading bacteria Shiraz Refinery soil. In study, nutrient agar (NA) mineral salt (MM2) were used as basic cultures. Using Techniques Replica plating, we transferred...

Phenol and phenolic compounds are the most common pollutants result of petrochemical industries. Their carcinogenic toxic effects have been recorded on human being. Since chemical methods removing these contaminants expensive, applying microorganisms is suitable substitution to remove compounds. The purpose this research isolate identify phenol degrading bacteria from mangrove sediments in Persian Gulf (Asaluyeh) study their growth kinetics degradation level. Nine samples were collected....

Polycyclic aromatic hydrocarbons are particularly important due to large distribution in the environment, high toxicity and their carcinogen mutagen properties. The purpose of this study was isolation identification phenanthrene degrading bacteria from soil around Oil Company Andimeshk (Iran) investigation growth kinetics. Sampling three stations done at two seasons, spring summer. Phenanthrene were isolated using enrichment method. Bacterial performed by biochemical tests 16S rRNA gene...

Chlorobenzoic acids are one of the environmental pollutants which contaminate soils and waters. Microorganisms have been used for removing pollution in area oil spill, nuclear waste, leakage from waste landfill, factory heavy metals. The aim this study was to identify 2-chlorobenzoic acid degrading bacteria around landfill centers (landfills) Shiraz city (Iran) evaluate their degradation rate. In study, surface various stations were collected winter spring inoculated mineral base medium...

Abstract Efficient drug delivery systems (DDSs) can potentially replace with conventional modalities in cancer therapy, like liver cancer. In this study, a novel folic acid (FA)‐functionalised and alginate (Alg)‐modified poly lactic‐co‐glycolic (PLGA) nanocomposite was developed for of doxorubicin (Dox) to HepG2 Huh7 cells. After synthesising the nanocarrier, several analytical devices, including FT‐IR, DLS, TGA, TEM, were employed its characterisation. Nano‐metric size (55 85 nm diameter),...

Abstract Liver cancer is one of the most common causes death all around globe. On other hand, conventional modalities, such as chemotherapy and surgery, have not been effectively suppressed incidence due to some deficiencies. As a result, novel folic acid (FA)‐decorated poly lactic‐co‐glycolic (PLGA)‐Alginate (Alg) nanocarrier was efficiently developed for active doxorubicin (Dox) delivery human HepG2 liver cells. The in vitro assays, including cell viability assay (MTT...

Mangrove forests are of the wooden plants which susceptible to contamination by oil. They like a reservoir could absorb much PAH compositions from oil contaminations. On other hand, contaminated sediments contain many types indigenous microorganisms able degrade compositions. This study was designed isolate biologically fluoranthene Persian Gulf and analyze their growth kenetics. The isolated bacteria included Bacillus circulans , Alcaligenes faecalis Enterobacter Listeria Staphylococcus....

Cd, Pb and Zn concentrations were determined in muscle liver of Capoeta trutta collected from northern Khuzestan province Dez River (southwest Iran) during March, 2012. Heavy metal varied significantly depending on the type tissue. Generally, showed lowest levels Cd metals tissues. Significant differences observed Zn, but nosignificant between concentration tissue liver. It was concluded that level heavy muscles fish within acceptable limits by WHO standards higher than standard. The main...
