Two fosmid libraries, totaling 13,200 clones, were obtained from bioreactor sludge of petroleum refinery wastewater treatment system. The library screening based on PCR and biological activity assays revealed more than 400 positive clones for phenol degradation. From these, 100 clones were randomly selected for pyrosequencing in order to evaluate the genetic potential of the microorganisms pres...
This study was an add-on study to the National Air Emission Monitoring Study (NAEMS). The objective of this study was to measure odor emissions and corresponding concentrations and emissions of target odorous gases. Odor and odorous gas measurements at four NAEMS sites (dairy barns in Wisconsin-WI5B and Indiana-IN5B, swine finisher barn in Indiana-IN3B and swine gestation/farrowing barns in Iow...
The white rot fungus Phanerochaete chrysosporium has significant pollutant-degrading capabilities with its oxidoreductases. The lignin-degrading enzyme system of this fungus also allows the breakdown of different organic pollutants (xenobiotics). The most significant enzymes in these processes are the lignin peroxidase and the manganese peroxidase. In this study, Phanerochaete chrysosporium str...
For several years, our laboratory has isolated numerous bacterial strains from soils and wastewater contaminated with toxic compounds in order to find useful bacteria that can degrade phenolic compounds such as phenol, chlorophenol, and nitrophenol. By enrichment, many phenolic compound-degrading bacteria have been isolated (Bae et al., 1996a, b; Baek et al., 2001; Yoon et al., 1999, 2000). Fur...
Cytotoxicity of 5 phenol derivatives (phenol, catechol, resorcinol, hydroquinone and phloroglucinol) was tested using a mouse 3T3 fibroblast cell line. Its relationships with structural and physicochemical properties were investigated. Linear regression analysis and Pearson's correlation coefficient were used to characterise the relationship between cytotoxicity (expressed by IC(50) values) and...
MicrosoftInternetExplorer4 Background and Objectives: Phenols in trace quantities are usually present in the treated effluent of many wastewater-treatment plants. Phenol compounds even at low concentration can cause toxicity, health and significant taste and odor problem in drinking waters. This research focuses on understanding the sorption process and developing a cost-effective technolo...
A strategy to increase shelf life of Empeltre olive oils could consist in the incorporation flavoring agents (rich antioxidant compounds). The aim this study was describe quality flavored with rosemary and garlic at different concentrations methods (maceration co-processing during malaxation). malaxation increased total phenol content capacity. Aromatization (added malaxation) more than 50%. Ch...
Recently almost all of the analytical methods have been used for analyzing and detecting of explosives, because of their importance in demining and unexploded ordnances operations. Fluorescence technique is one of the analytical methods. The unique features of this method caused to lots of researches in the mentioned applications. In present study, the fluorophores such as pyrene, phenol red, m...
phenol and phenol compounds are environmental pollutants present in industrial wastewaters such as, coal tar, oil refineries and petrochemical plants exist. phenol removal from industrial effluent is extremely important in protection of environment. recently phenol biodegradation has been considered. marine bacteria are the most important phenol biodegrader. in this study, the phenol-degrading ...
Bioactive components play an important role in human health. In general, bioactive compounds of fruits decline during storage. Therefore, maintaining fruits bioactive compounds during storage is very important. In this study, effects of pre-harvest CaCl2 sprays (0, 1, 2, and 4%) at different fruit development stages (120, 140, and 160 days after full bloom) on maintaining fruit quality of thre...
