Biodegradation of high-molecular-weight polycyclic aromatic hydrocarbons by bacteria.
Interest in the biodegradation mechanisms and environmental fate of polycyclic aromatic hydrocarbons (PAHs) is prompted by their ubiquitous distribution and their potentially deleterious effects on human health. PAHs constitute a large and diverse class of organic compounds and are generally described as molecules which consist of three or more fused aromatic rings in various structural configu...

متن کاملPromoting healthy weight--the new environmental frontier.
1 One of the world's greatest tragedies is that many parts of the planet suffer from food shortages and starvation arising largely from drought, floods, corruption and conflict, yet, at the same time, hundreds of millions of people in both developed and developing countries are overweight and obese due to 'over-nourishment' and 'under-activity'. Indeed the problem of excessive weight is now so ...

متن کاملBiodegradation of high-molecular-weight polycyclic aromatic hydrocarbons by a wood-degrading consortium at low temperatures.
This study evaluates the ability of two bacterial consortia (C2PL05 and BOS08), extracted from very different environments, to degrade low- (naphthalene, phenanthrene, anthracene) and high- (pyrene, perylene) molecular-weight polycyclic aromatic hydrocarbons (PAHs) at high (15-25 °C) and low (5-15 °C) temperature ranges. C2PL05 was isolated from a soil in an area chronically and heavily contami...
