Isolation and characterization of an acidophilic, heterotrophic bacterium capable of oxidizing ferrous iron.
A heterotrophic bacterium, isolated from an acidic stream in a disused pyrite mine which contained copious growths of "acid streamers," displayed characteristics which differentiated it from previously described mesophilic acidophiles. The isolate was obligately acidophilic, with a pH range of 2.0 to 4.4 and an optimum pH of 3.0. The bacterium was unable to fix carbon dioxide but oxidized ferro...
متن کاملFerrous-iron-dependent uptake of L-glutamate by a mesophilic, mixotrophic iron-oxidizing bacterium strain OKM-9.
Strain OKM-9 is a mesophilic, mixotrophic iron-oxidizing bacterium that absolutely requires ferrous iron as its energy source and L-amino acids (including L-glutamate) as carbon sources for growth. The properties of the L-glutamate transport system were studied with OKM-9 resting cells, plasma membranes, and actively reconstituted proteoliposomes. L-Glutamate uptake into resting cells was total...
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 کاملPerchlorate reduction by a novel chemolithoautotrophic, hydrogen-oxidizing bacterium.
Water treatment technologies are needed that can remove perchlorate from drinking water without introducing organic chemicals that stimulate bacterial growth in water distribution systems. Hydrogen is an ideal energy source for bacterial degradation of perchlorate as it leaves no organic residue and is sparingly soluble. We describe here the isolation of a perchlorate-respiring, hydrogen-oxidiz...
متن کاملSuperoxide production by a manganese-oxidizing bacterium facilitates iodide oxidation.
The release of radioactive iodine (i.e., iodine-129 and iodine-131) from nuclear reprocessing facilities is a potential threat to human health. The fate and transport of iodine are determined primarily by its redox status, but processes that affect iodine oxidation states in the environment are poorly characterized. Given the difficulty in removing electrons from iodide (I(-)), naturally occurr...
