1. Development of multiplex loop-mediated isothermal amplification for three foodborne pathogens
Abstract Staphylococcus aureus, Salmonella, and Shigella are three major foodborne pathogenic microorganisms that cause global public health problems. We developed a multiplex loop-mediated isothermal amplification (mLAMP) assay for simultaneous detection of S. aureus nuc, Salmonella fimY, and Shigella ipaH in fresh fruit juice using three sets of primers.

2. Evaluation of Phytoremediation Potential of Castor Cultivars for Heavy Metals from Soil
RESUMO: A fitorremediação é uma ferramenta útil para recuperar solos contaminados com metais pesados. Este estudo foi realizado para testar dois cultivares de mamona (Ricinus communis) [Local e DS-30] quanto à fitoextração de metais pesados de solo contaminado por concentrações conhecidas de sete metais (Cu, Cr, Fe, Mn, Ni, Pb e Zn). Um ensaio em va

5. Application of the fundamental parameter method to the assessment of major and trace elements in soil and sediments from Osamu Utsumi uranium mine by WDXRF
Abstract Wavelength dispersive X-ray fluorescence spectrometry (WDXRF) is a suitable technique for the characterization of contaminated mining sites, providing a quick and reliable screening for areas of significant contamination. This study established and validated a non-destructive methodology for quantitative simultaneous determination of major and minor

6. Simultaneous biodegradation of phenol and cyanide present in coke-oven effluent using immobilized Pseudomonas putida and Pseudomonas stutzeri
ABSTRACT Discharge of coke-oven wastewater to the environment may cause severe contamination to it and also threaten the flora and fauna, including human beings. Hence before dumping it is necessary to treat this dangerous effluent in order to minimize the damage to the environment. Conventional technologies have inherent drawbacks however, biological treatm

7. Heavy metal tolerance traits of filamentous fungi isolated from gold and gemstone mining sites
ABSTRACT Increased environmental pollution has necessitated the need for eco-friendly clean-up strategies. Filamentous fungal species from gold and gemstone mine site soils were isolated, identified and assessed for their tolerance to varied heavy metal concentrations of cadmium (Cd), copper (Cu), lead (Pb), arsenic (As) and iron (Fe). The identities of the

8. Preliminary assessment of Miramar Petrochemical Harbor as PAH source to Guajará bay (Belém-PA-Brazil) surface sediments
Abstract A preliminary study on a petrochemical harbor as a potential source of polycyclic aromatic hydrocarbons (PAH) to surface sediments of Guajará bay, located in Belém City, Pará State, Brazil, over the last 10 years is presented here. The 16 priority USEPA PAH were identified and quantified. Surface sediment samples, collected at 5 sites in the bay,

9. Design of Ground Penetrating Radar Antenna for Detecting Soil Contamination at L-band Frequencies
Abstract Maintenance of oil pipelines is an issue of great concern for oil companies. Soil contamination is caused by oil leaks from underground pipelines. Ground penetrating radar (GPR) is a rapid and relatively inexpensive technique used for locating and characterizing soil contaminated sites without producing fractures and causing further migration of con

10. The effect of heavy metal contamination on the bacterial community structure at Jiaozhou Bay, China
Abstract In this study, determination of heavy metal parameters and microbiological characterization of marine sediments obtained from two heavily polluted sites and one low-grade contaminated reference station at Jiaozhou Bay in China were carried out. The microbial communities found in the sampled marine sediments were studied using PCR-DGGE (denaturing gr

11. EVALUATION OF POTENTIAL METHANE GENERATION IN THE INVESTIGATION OF AN ABANDONED CONTAMINATED LANDFILL IN SANTIAGO, CHILE
Abstract This study presents the environmental evaluation of an abandoned and potentially contaminated landfill using analyses for the presence of heavy metals and for methane generation potential. The site is located in the city of Santiago, Chile, and was used as a rural landfill for domestic, industrial and construction waste until 1978, but is now in a h

12. Soil bacteria showing a potential of chlorpyrifos degradation and plant growth enhancement
ABSTRACT Background: Since 1960s, the organophosphate pesticide chlorpyrifos has been widely used for the purpose of pest control. However, given its persistence and toxicity towards life forms, the elimination of chlorpyrifos from contaminated sites has become an urgent issue. For this process bioremediation is the method of choice. Results: Two bacterial
