Douglas Pino Herrera 1 Details. Hide details. Abstract : Polycyclic Aromatic Hydrocarbon PAH -contaminated soils are a great environmental and public health concern nowadays. Aerobic soil-slurry bioreactor technology has emerged as an effective and feasible technique with a high remediation potential, especially for the fine soil fractions, which often contain the highest pollution levels and are hard to treat with conventional approaches.

Polycyclic Aromatic Hydrocarbons (PAHs): Sources of Ambient QuinonesCarolyn L. Nanca, Kimberly D. Neri, Anna Christina R. Ngo, Reuel M.
Bennett, Gina R. Journal of Health and Pollution 1 September ; 8 19 : Polycyclic aromatic hydrocarbons PAHs are common environmental contaminants which are highly toxic due to their carcinogenic and mutagenic effects. They are released into the environment by incomplete combustion of solid and liquid fuels, accidental spillage of oils and seepage from industrial activities.
One of the promising processes mitigating PAHs is through biodegradation. However, conventional microbiological treatment processes do not function well at high salt concentrations.
The Effects Of Polycyclic Aromatic Hydrocarbons On The Organ System Of Aquatic Invertebrates
Hence, utilization of halophilic bacteria should be considered. This study aimed to assess the ability of halophilic bacteria isolated from local salt beds in Pangasinan and Cavite, the Philippines, to degrade PAHs pyrene, fluorene and fluoranthene. Polycyclic aromatic hydrocarbon-tolerant halophilic bacteria collected from two sampling sites were phenotypically characterized, molecularly identified and tested to determine their potential to see more the PAHs pyrene, fluorene and fluoranthene at a hypersaline condition. Best PAH degraders were then assayed to identify the optimal degradation using such parameters as pH, temperature After Treatment Of Polycyclic Aromatic Hydrocarbons PAH concentration.
Testing for enzyme degradation was also done to determine their baseline information. Extraction and analysis of degraded PAHs were performed using centrifugation and UV-vis spectrophotometry. Twelve isolates from both collection sites tolerated and grew in culture with selected PAHs.
These were identified into four genera HalobacillusHalomonasChromohalobacterand Pontibacillus.
Degrader biomass and PAH degradation were invariably negatively correlated. Qualitative tests with and without peptone as a nitrogen source implied enzymatic degradation.
Informations
Polycyclic aromatic hydrocarbons utilized by these halophilic bacteria served as a sole source of carbon and energy. Implications of biodegradation of the two best isolates show that high molecular weight HMW 4-ring pyrene tends to be degraded better by Gram-positive bacteria and low molecular weight 3-ring fluorene by Gram-negative degraders. Halophilic bacteria constitute an untapped natural resource for biotechnology in the Philippines. The present study demonstrated their potential use in bioremediation of recalcitrant hydrocarbons in the environment. Competing Interests.
