Abstract

The aim of this study is to reveal the ability of utilizing different aromatic hydrocarbons (p-hydroxybenzoic acid, naphthalene, phenanthrene, and pyrene) by a halotolerant bacterial strain, Chromohalobacter sp., under saline conditions. The aromatic hydrocarbon degradation pathways were identified. PCR amplification was carried to define the gene zones which codify the dioxygenases of the isolates. The possible gene zones of catechol 1, 2 dioxygenase and protocatechuate 3, and 4 dioxygenase were determined. According to the PCR amplification and enzyme test results Chromohalobacter sp. utilizes aromatic hydrocarbons by the ortho cleavage of the s-ketoadipate pathway. In this study, it was concluded that this isolate can be used in bioremediation studies of saline environments contaminated with aromatic hydrocarbons.

嗜色盐杆菌对芳烃的利用能力。

本研究的目的是揭示耐盐细菌嗜盐杆菌(Chromohalobacter sp.)在盐水条件下利用不同芳香烃(对羟基苯甲酸、萘、菲和芘)的能力。确定了芳烃的降解途径。用PCR扩增确定了双加氧酶的基因区。确定了儿茶酚1、2双加氧酶和原儿茶酚3、4双加氧酶可能的基因区。根据PCR扩增和酶测结果，嗜盐杆菌通过邻位裂解s-酮己二酸途径利用芳烃。本研究结果表明，该分离物可用于芳香烃污染的盐水环境的生物修复研究。

期刊介绍： Cessation. Ekoloji is an international journal that focuses on papers that report results from original research on all disciplines engaged in the field of environmental research. We welcome articles that cover the entire spectrum of environmental problems and environmental pollutants, whether chemical, biological or physical. Its coverage extends to all environmentally related issues: air and water pollution, solid waste, noise, recycling, natural resources, ecology and environmental protection. It includes articles on basic and applied environmental pollution research, including environmental engineering and environmental health. All types of pollution are covered, including atmospheric pollutants, detergents, fertilizers, industrial effluents, metals, mining wastes, oil, pesticides, plastics, radioactive materials and sewage. It also includes research papers on ecological and environmental issues such as climate change, biodiversity. The primary criteria for publication are scientific quality and ecological/environmental significance. The journal will be read and contributed to by biologists, applied ecologists, environmental scientists, natural resource specialists, environmental engineers, environmental health specialists, agro-ecologists, veterinaries, agricultural engineers, landscape planners and designers. The journal welcomes full "research papers" and short "research notes", only in the English language.
