Background and Objective: PAHs are non-polar organic compounds consisting of two or more fused benzene multi-rings. Among these compounds, acenaphthene is a multi-ring hydrocarbon that occurs abundantly in nature. Use of microorganisms to clean the contaminations of soil can be cheap and effective. The most important acenaphthene-degrading bacteria are pseudomonas, micrococcus, and Bacillus. Th...
Abstract Background Isoprene accounts for about half of total biogenic volatile organic compound emissions globally, and as a climate active gas it plays significant varied role in atmospheric chemistry. Terrestrial plants are the largest source isoprene, with willow ( Salix ) making up one most groups isoprene producing trees. Bacteria act biological sink those bacteria associated high isopren...
this thesis aims at putting together two of the vestest areas of study there is in humanities: bioethics and literature. the two novels in question, oryx and crake and the year of the flood, are considered as some of the most succssful examples of spculative fiction. in these novels the biological and environmental issues raised as looked at from a bioethics point of view.
Mangrove forests are coastal ecosystems that found worldwide in tropical and subtropical zones. Oil spill causes damage to these marine ecosystems. The objective of this study is study the oil-degrading bacteria in some mangrove forests that located at Persian Gulf. In this study sediments and plant materials were collected from mangrove forests at Persian Gulf (Minab and Khamir ports). Oil-deg...
Phenol is one of the major aromatic pollutants among variety of toxic compounds. Phenol is a man- made as well as a naturally occurring aromatic compound and an important intermediate in the biodegradation of natural and industrial aromatic compounds. To clean up the aromatic contaminated sites a bioremediation method is considered as an economical and safe approach for the environment. In this...
Abstract The endophytic bacteria can be in symbiosis with host plants, owing to the natural stability advantages degrading pollutants. To explore technological feasibility of this method for indoor formaldehyde removal, a system combining and plants was established. In present study, highly efficient formaldehyde-degrading Ochrobactrum intermedium , named strain ZH-1, successfully induced antib...
