The Effects of Silver Nanoparticles (AgNPs) on Thermophilic Bacteria: Antibacterial, Morphological, Physiological and Biochemical Investigations.

Since thermophilic microorganisms are valuable sources of thermostable enzymes, it is essential to recognize the potential toxicity of silver nanoparticles used in diverse industrial sectors. Thermophilic bacteria 2Cx, 3CA, 3CA1, FMB1, and FMB2-1 were selected, and their MIC and MBC values were assessed by treatment with AgNPs in a range of 62.5-1500 μg mL.

Effects of endosulfan, thiamethoxam, and indoxacarb in combination with atrazine on multi-biomarkers in Gammarus kischineffensis.

Studies addressing the toxicity of pesticides towards non-target organisms focus on the median lethal concentration and biochemical response of individual pesticides. However, when determining environmental risks, it is important to test the combined effects of pesticides, such as insecticides and herbicides, which are frequently used together in agricultural areas. Here we aimed to investigate the toxic effects of the combined use of the herbicide atrazine and the insecticides, endosulfan, indoxacarb, and thiamethoxam on Gammarus kischineffensis.

Purification and Characterization of Thermostable and Detergent-Stable α-Amylase from sp. AH1.

A thermostable and detergent-stable α-amylase from a newly isolated sp. AH1 was purified and characterized. Maximum enzyme production (1874.

Extremely low-frequency magnetic field induces manganese accumulation in brain, kidney and liver of rats.

The aim of the present study was to determine the effects of extremely low-frequency magnetic field (ELF-MF) on accumulation of manganese (Mn) in the kidney, liver and brain of rats. A total of 40 rats were randomly divided into eight groups. Four control groups received 0, 3.

Geobacillus subterraneus subsp. aromaticivorans subsp. nov., a novel thermophilic and alkaliphilic bacterium isolated from a hot spring in Sırnak, Turkey.

A new thermophilic spore-forming strain Ge1(T) was isolated from the Guclukonak hot spring in Sırnak, Turkey. The strain was identified by using a polyphasic taxonomic approach. Strain Ge1(T) was Gram-positive, spore-forming, alkaliphilic rod-shaped, motile, occurring in pairs or filamentous.

Cd, Cu, Ni, Mn and Zn resistance and bioaccumulation by thermophilic bacteria, Geobacillus toebii subsp. decanicus and Geobacillus thermoleovorans subsp. stromboliensis.

Bioaccumulation and heavy metal resistance of Cd(2+), Cu(2+), Ni(2+), Zn(2+) and Mn(2+) ions by thermophilic Geobacillus toebii subsp. decanicus and Geobacillus thermoleovorans subsp. stromboliensis were investigated.

The effects of long-term exposure to extremely low-frequency magnetic fields on bone formation in ovariectomized rats.

The effects of long-term extremely low-frequency magnetic field (ELF-MF) exposure on bone formation and biochemical markers were investigated in ovariectomized rats. Sixty mature female Sprague-Dawley rats were randomly divided into four different groups (n = 15): (i) unexposed control (CTL); (ii) ovariectomized only (OVX); (iii) non-ovariectomized, exposed (SHAM + ELF-MF); and (iv) ovariectomized, exposed (OVX + ELF-MF). The third and fourth groups were exposed to 1.

Production and characterization of partially purified extracellular thermostable α-amylase by Bacillus subtilis in submerged fermentation (SmF).

A Bacillus strain was isolated from soil samples from the campus area of Dicle University. Based on 16S ribosomal RNA sequencing, the microorganism was closely related to Bacillus subtilis. Effects of different culture medium, incubation time, carbon and nitrogen sources, and various starches, flours, and chemicals on α-amylase production were examined.

Anoxybacillus kamchatkensis subsp. asaccharedens subsp. nov., a thermophilic bacterium isolated from a hot spring in Batman.

A new thermophilic spore-forming strain KG8(T) was isolated from the mud of Taslidere hot spring in Batman. Strain KG8(T) was aerobe, Gram-positive, rod-shaped, motile, occurring in pairs or filamentous. Growth was observed from 35-65 degrees C (optimum 55 degrees C) and at pH 5.
