Bioremediation of Crude Oil by Haematococcus Pluvialis: A Preliminary Study
نویسندگان
چکیده
Nowadays, oil pollution is one of the main environmental problems. The current methods for recovering spills mainly involve chemical agents, but scientific research has focused on more natural and less harmful techniques environment, including a consortium bacteria microalgae to clean up water contaminated by hydrocarbons. purpose this preliminary study was evaluate ability microalga belonging Chlorophyceae grow in presence crude remove principal contaminants. H. pluvialis, which usually used nutraceutical purposes, thanks production astaxanthin, able anaerobic conditions, varying its metabolism from autotrophic heterotrophic, exploiting carbon present solution deriving 1% oil. Furthermore, results bioremediation showed relevant reduction pollutants such as nitrate, fluoride, sulfate, phosphate. most important aspect after 160 days hydrocarbon concentration inside not only culture medium (−32%) also algal biomass (−80.25%), demonstrating an optimized degradation rather than simple absorption alga.

Bioremediation of Heavy Crude Oil Contamination
Crude oil contamination is one of the major environmental concerns and it has drawn interest from researchers and industries. Heavy oils contain 24-64% saturates and aromatics, 14-39% resins and 11-45% asphaltene. Resins and asphaltenes mainly consist of naphthenic aromatic hydrocarbons with alicyclic chains which are the hardest to degrade. Crude oil biodegradation process, with its minimal en...
متن کاملBioremediation of soil contaminated crude oil by Agaricomycetes
BACKGROUND One of the most important environmental problems is the decontamination of petroleum hydrocarbons polluted soil, particularly in the oil-rich country. Bioremediation is the most effective way to remove these pollutants in the soil. Spent mushroom compost has great ability to decompose lignin-like pollution. The purpose of this study was the bioremediation of soil contaminated with cr...
متن کاملPreliminary Clinical Evaluation of Toxicity and Efficacy of A New Astaxanthin-rich Haematococcus pluvialis Extract
Astaxanthin (Ax), a carotenoid ubiquitously distributed in microorganisms, fish, and crustaceans, has been known to be a potent antioxidant and hence exhibit various physiological effects. We attempted in these studies to evaluate clinical toxicity and efficacy of long-term administration of a new Ax product, by measuring biochemical and hematological blood parameters and by analyzing brain fun...
