Özdemir, Sadin; Turkan, Zeynep; Kılınç, Ersin; Altuner, Elif Esra; Şen, Fatih (Institute for Ionics, 2023)In this article, the effects of copper (Cu(II)) and manganese (Mn(II)) ions on the superoxide dismutase (SOD) and catalase enzymes (CAT) of the thermophilic Anoxybacillus flavithermus (A. flavithermus) were thoroughly ... -
Bioaccumulation, resistance, removal of U(VI) and Th(IV) and their rffects on antioxidant enzymes on thermophilic anoxybacillus flavithermus ST15
Acer, Ömer; Kılınç, Ersin; Özdemir, Sadin (Taylor & Francis, 2021)In this research, a novel heavy metals resistance thermophilic Anoxybacillus flavithermus ST15 was isolated from a hot spring mud sample in Afyonkarahisar (Omer). 16S rRNA analyzing revealed that strain ST15 was 99.7% ... -
A fungal functionalized magnetized solid phase extractor for preconcentrations of Pb(II), Mn(II), and Co(II) from real samples
Özdemir, Sadin; Yalçın, Mustafa Serkan; Kılınç, Ersin; Soylak, Mustafa (Elsevier Ltd., 2023)Due to increasing industrialization and overpopulation, the amount of toxic metals is increasing in the environment, including air, soil, water, and food. Solid phase extraction is an efficient and ideal technique to ... -
Investigations of Hg(II) and Pb(II) tolerance, removal and bioaccumulation and their effects on antioxidant enzymes on thermophilic Exiguobacterium profundum
Akkoyun, Mahire Bayramoğlu; Özdemir, Sadin; Kılınç, Ersin; Birhanli, Emre (Taylor and Francis Inc., 2020)Hg(II) and Pb(II) tolerance, removal, bioaccumulation and effects on antioxidant enzymes of thermophilic Exiguobacterium profundum were investigated. The results indicated that Hg(II) was more toxic than Pb(II) to E. ... -
Magnetic solid-phase extraction based on Coriolus versicolor-immobilized ?-Fe2O3 nanoparticles for preconcentration and determination of Al(III) in water and food samples
Özdemir, Sadin; Yalcın, Mustafa Serkan; Kılınç, Ersin; Soylak, Mustafa (TUBITAK, 2019)A method for preconcentration of Al(III) prior to its determination by inductively coupled plasma-optical emission spectrometry (ICP-OES) was developed because the sensitivity of ICP-OES is insufficient for trace-level ... -
