this study was undertaken to identify key elements for obtaining community interest and motivate them to support eliminate malaria in the places that malaria is no longer a perceived threat.sequential explanatory mixed methods research design used to provide more comprehensive evidence research. a questionnaire was developed after reviewing the literature relating to community participation for...

The present study examined the biodegradation rate of benzene vapors in a two phase stirred tank bioreactor by a bacterial consortium obtained from wastewater of an oil industry refinery house. Initially, the ability of the microbial consortium for degrading benzene was evaluated before running the bioreactor. The gaseous samples from inlet and outlet of bioreactor were directly injected into a...

BACKGROUND Bacteria have long been recognized as the primary etiology for pulpal and periapical lesions, which necessitates the elimination of bacteria from the root canal system. In primary teeth, irrigation and debridement is the main protocol required to disinfect the canal. Biomechanical preparation cannot be vigorously done on the primary teeth due to anatomical barrier such as thin and fl...

Doenjang is a traditional Korean fermented soybean product that provides a major source of protein. In this study, a total of 18 different home-made doenjang samples were examined for the presence of foodborne pathogens and the total aflatoxin levels. Using an enzyme-linked immunosorbent assay to assess microbial quality and potential public health risk, we showed that total coliform levels in ...

Possible enhancement of biodegradation of petroleum hydrocarbons in agricultural soil after tank truck accident (~5000 mg/kg dry soil initial concentration) by bioaugmentation of diesel degrading Pseudomonas fluorescens strain and addition of abiotic additives (humates, zeolite) was studied in a 9-month pot experiment. The biodegradation process was followed by means of analytical parameters (h...

Removal of acetone and methyl isopropyl ketone (MIPK) in a composite bead biofilter was investigated. Both microbial growth rate kg and biochemical reaction rate kd would be inhibited at higher inlet concentration. For the microbial growth process, the kg value of MIPK was greater than that of acetone and the inhibitive effect for MIPK was more sensitive than that for acetone in the average inl...

Zeolite LTA was synthesized in the laboratory and loaded with silver ions by isomorphous substitution technique. The silverloaded zeolite A (Ag-LTA) was characterized by X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and Fourier transformed infrared (FTIR) spectroscopy. XRD and SEM analysis showed little or no changes in the phase purity of a...

Compounds interaction on biodegradation of toluene and methyl ethyl ketone (MEK) mixtures in a composite bead biofilter was investigated. The biodegradation rate of two compounds in the exponential growth phase and stationary phase for the single compound and two compounds mixing systems was determined. For the single compound system, the biodegradation rate of two compounds in the microbial gr...

This paper introduces the hierarchical computational framework OptStrain aimed at guiding pathway modifications, through reaction additions and deletions, of microbial networks for the overproduction of targeted compounds. These compounds may range from electrons or hydrogen in biofuel cell and environmental applications to complex drug precursor molecules. A comprehensive database of biotransf...
