Effect of external pH perturbations on in vivo protein synthesis by the acidophilic bacterium Thiobacillus ferrooxidans.
The response of the obligate acidophilic bacterium Thiobacillus ferrooxidans to external pH changes is reported. When T. ferrooxidans cells grown at pH 1.5 were shifted to pH 3.5, there were several changes in the general protein synthesis pattern, including a large stimulation of the synthesis of a 36-kDa protein (p36). The apparent low isoelectric point of p36, its location in the membrane fr...
متن کاملFacultative Iron-Oxidizing Bacterium, Thiobacillus ferrooxidans
Properties ofa heat-labile glucose transport system in Thiobacillusferrooxidans strain AP-44 were investigated with iron-grown cells. [14C]glucose was incorporated into ceil fractions, and the cells metabolized [14C]glucose to 14CO2. Amytal, rotenone, cyanide, azide, 2,4-dinitrophenol, and dicyclohexylcarbodiimide strongly inhibited [14C]glucose uptake activity, suggesting the presence of an en...
متن کاملCharacterization of the petI and res operons of Acidithiobacillus ferrooxidans.
DNA sequence analysis and bioinformatic interpretations have identified two adjacent clusters of genes potentially involved in the formation of a bc1 complex and in the maturation of a cytochrome c-type protein in two strains (ATCC 19859 and ATCC 33020) of the acidophilic, chemolithoautotrophic bacterium Acidithiobacillus ferrooxidans (formerly Thiobacillus ferrooxidans). Reverse transcriptase-...
متن کاملCytoplasmic pH homeostasis in an acidophilic bacterium, Thiobacillus acidophilus.
The cytoplasmic buffering capacity of Thiobacillus acidophilus (along with membrane properties) is responsible for the cytoplasmic pH homeostasis in metabolically compromised cells. When a large influx of H+ occurs, the cytoplasmic buffering capacity prevents drastic changes in pH; in addition, this influx, by increasing the positive membrane potential, eventually leads to a cessation of furthe...
متن کاملRemoval of Heavy Metals from Urban Sewage Sludge Using Acidophilic Thiobacillus ferrooxidans
Background & objectives: The presence of heavy metals in urban sewage sludge limits its use as a soil modifier. The purpose of this study was to remove heavy metals (Cu, Zn, Cd and Pb) from urban sewage sludge using Acidophilic Thiobacillus ferrooxidans bacteria. Methods: In this experimental study, the sludge samples were collected from Shiraz wastewater treatment plant. Bioleaching tests were...
