The combined anaerobic-aerobic conditions in air-cathode single-chamber MFCs were used to completely mineralize pentachlorophenol (PCP; 5 mg/L), in the presence of acetate or glucose. Degradation rates of 0.140 ± 0.011 mg/L-h (acetate) and 0.117 ± 0.009 mg/L-h (glucose) were obtained with maximum power densities of 7.7 ± 1.1 W/m(3) (264 ± 39 W/m(2), acetate) and 5.1 ± 0.1 W/m(3) (175 ± 5 W/m(2)...

Mangrove sediment harbors a unique microbiome and is a hospitable environment for a diverse group of bacteria capable of oil biodegradation. Our goal was to understand bacterial community dynamics from mangrove sediments contaminated with heavy-oil and to evaluate patterns potentially associated with oil biodegradation is such environments. We tested the previously proposed hypothesis of a two-...

E-nose (Electronic nose), which is an array of chemical sensors, is widely used in food industry and pollution control. Nowadays e-nose technology has become powerful tool to evaluate the aroma compounds during the quality control process. This work is intended to detect biological water contaminants like coliform group of bacteria in drinking water. However, a number of limitations are associa...

The biological treatment processes found wide applications in wastewater, air & solid waste pollution control. The need for alternate cost effective treatment technologies led to similar biological treatment processes for waste gas streams. One such treatment technology is biofiltration. Biofiltration technology utilizes the microorganisms to biologically degrade Volatile Organic Compounds (VOC...

As sea surface temperatures rise and the global human population increases, large-scale field observations of marine organism health and water quality are increasingly necessary. We investigated the health of corals from the family Fungiidae using visual observations in relation to water quality and microbial biogeochemistry parameters along 1300 km of the Red Sea coast of Saudi Arabia. At larg...

The rapid development of resistance in bacteria is an evolutionary response to the selective pressure of antibiotics and results from natural selection. It is established that microbial adaptation evolves, and the cause for the development of antibiotic resistance is the widespread misuse of antibiotics. Pollution of the environment by antibiotic resistance genes can increase the chances of hum...

There is a growing demand for healthy and safe food, strategy against an increasing risk of biotic factors such as disease, and threats to agricultural and food production from changing global climate condition. Nanotechnology is a new discipline and developed innovative tools to revolutionize the agricultural and food industry through diagnosis and treatment of diseases, enhancing the ability ...

Scientists have known since the 1890s that insects are vulnerable to diseases. However, it was not until the early 1950s that field demonstrations by Steinhouse in California led to the commercial production of biopesticides. The federal government registered the first microbial product in 1948, the bacterium Bacillus popillae, to control the Japanese beetle in turf. Although many entomopathoge...

Trinitrotoluene (TNT), a commonly used explosive for military and industrial applications, can cause serious environmental pollution. 28-day laboratory pot experiment was carried out applying bioaugmentation using laboratory selected bacterial strains as inoculum, biostimulation with molasses and cabbage leaf extract, and phytoremediation using rye and blue fenugreek to study the effect of thes...

Persistent heavy metal pollution poses a major threat to all life forms in the environment due to its toxic effects. These metals are very reactive at low concentrations and can accumulate in the food web, causing severe public health concerns. Remediation using conventional physical and chemical methods is uneconomical and generates large volumes of chemical waste. Bioremediation of hazardous ...
