Acute and chronic pollution of environments with crude oil does not bode well for biota living within the vicinity of polluted environments. This is due to environmental and public health concerns on the negative impact of crude oil pollution on living organisms. Enhancing microbial activities by adding nutrients and other amendments had proved effective in pollutant removal during bioremediati...

Since intensive poultry production is accompanied by as high as possible densities of birds within buildings, this exposes poultry house workers to elevated concentrations of bioaerosol that is mainly emitted by birds. Exposure to dust containing pathogenic microbial and parasitic agents may cause asthma, asthma-like syndrome, mucous membrane irritation, chronic bronchitis, and allergic alveoli...

Polyhydroxyalkanoates (PHAs) are a family of biopolyesters synthesized by many types of bacteria as carbon and energy reserve materials. PHAs combine properties of thermal processibility, biodegradability, biocompatibility and sustainability. They have attracted attention from fermentation, materials and biomedical industries. Recent environmental concerns such as CO(2) emissions and plastic po...

Diffuse groundwater pollution from agricultural land use may impact the microbial groundwater community, which was investigated as Community-Level Physiological Profiles (CLPP) using EcoPlate™. Water was sampled from seven piezometers and a spring in a small agricultural catchment with diffuse herbicide and nitrate pollution. Based on the Shannon-Wiener and Simpson's diversity indices the diver...

This study aimed to identify specific river sources of fecal contamination by applying pulsed-field gel electrophoresis (PFGE) to environmental water samples from a recreational beach in Japan. The genotypes of all Enterococcus faecium and Enterococcus faecalis strains used as indicators of fecal pollution on the recreational beach and rivers were analyzed by PFGE, and the PFGE profiles of the ...

Over the past three decades heavy metal pollution has increased substantially in Cochin estuary, south west coast of India. Here we studied the distribution, diversity and enzyme expression profile of culturable microbial population along a pollution gradient. The distribution of resistance against 5 mM concentration of Zn, Co, Ni and Cu was observed among 90-100% of bacterial isolates retrieve...

Cattle manure harbors microbial constituents that make it a potential source of pollution in the environment and infections in humans. Knowledge of, and microbial assessment of, manure is crucial in a bid to prevent public health and environmental hazards through the development of better management practices and policies that should govern manure handling. Physical, chemical and biological met...

Knowledge about the relationship between microbial community structure and hydrogeochemistry (i.e., pollution, redox and degradation processes) in landfill leachatepolluted aquifers is required to develop tools for predicting and monitoring natural attenuation. In this study analyses of pollutant and redox chemistry were conducted in parallel with culture-independent profiling of microbial comm...

Although oil-based drilling fluids are of paramount practical and economical interest, they represent a serious source of pollution, once released into the environment as drill cuttings. The aim of this study is to assess the capability of isolated microorganisms to degrade gasoil fuel. The commonly used physicochemical and biodegradation remediation techniques of petroleum contaminated soil we...
