A 2,2-dichloropropionic acid-degrading novel Pseudomonas fluorescence strain fatsa001: isolation, identification, and characterization

Gülbübü KURMANBEKOVA | Yılmaz KAYA

There are mounting concerns over the high concentrations of non-biogenic, toxic halogenated organic compounds being liberated into the ecosystem. Therefore, this study’s isolation of a novel bacterium from a contaminated stream in Fatsa, Ordu, Turkey, adept in degrading 2,2-dichloropropionic (of 2,2-DCP) is a welcome endeavor. The ability of the bacterial isolate to utilize 2,2-DCP as the sole carbon and energy source was discovered when the bacterium was observed to grow well on liquid minimal media containing 20 mM of 2,2-DCP, showing a doubling time of 14.2 h. The following genetic and bioc ...More

The usability of Juniperus virginiana L. as a biomonitor of heavy metal pollution in Bishkek City, Kyrgyzstan

Zeki SEVEROĞLU | İlhan DOĞAN | Gülbübü KURMANBEKOVA

Uncontrolled and unplanned urbanization and industrialization due to increase of population and rapid industrial development have created severe environmental problems in Kyrgyzstan during the last few decades. In this study, Juniperus virginiana, a dioecious species, was employed in order to make assessment of the heavy metal pollution rate in the area and of the heavy metal pollution impact on the mineral nutrient status of the plant. For this study, leaf (washed and unwashed) and bark samples of J. virginiana, and its co-located soil samples were collected from eight different stations, all ...More

Assessment of pollution at the former uranium waste dumpsite near kaji-Say Village/Kyrgyzstan: a genetic and physiological investigation

İbrahim İlker ÖZYİĞİT | Bermet KIDIRALİYEVA | Kadırbay ÇEKİROV | Gülbübü KURMANBEKOVA | Nurzat ŞAYKİYEVA

Kyrgyzstan still suffers from the past practices of radioactive industry operated by the Soviet Union that caused significant impact on ecosystems in this region, especially related with storage of uranium in inadequate conditions. There are at least 50 abandoned sites used as radioactive waste dumps in the country. Due to the pressure of natural and anthropogenic reasons, the structural foundations of mine waste dumps are gradually losing their integrities. Here, particular interest of our research is to reveal current state of radioactive contamination and to make evaluation on the radiologi ...More
