Iron isotope fractionation by Fe(II)-oxidizing photoautotrophic bacteria
Photoautotrophic bacteria that oxidize ferrous iron (Fe[II]) under anaerobic conditions are thought to be ancient in origin, and the ferric (hydr)oxide mineral products of their metabolism are likely to be preserved in ancient rocks. Here, two enrichment cultures of Fe(II)-oxidizing photoautotrophs and a culture of the genus Thiodictyon were studied with respect to their ability to fractionate ...
متن کاملNitrogen isotope effects induced by anammox bacteria.
Nitrogen (N) isotope ratios ((15)N/(14)N) provide integrative constraints on the N inventory of the modern ocean. Anaerobic ammonium oxidation (anammox), which converts ammonium and nitrite to dinitrogen gas (N2) and nitrate, is an important fixed N sink in marine ecosystems. We studied the so far unknown N isotope effects of anammox in batch culture experiments. Anammox preferentially removes ...
متن کاملP32 Uptake by Nuclei
1. A method for isolating nuclei in quantity from mammalian tissues is described. 2. The rate of uptake of radioactive phosphorus by nuclei is found to be quite rapid. The phosphorus was shown not to be taken up by exchange. 3. Nuclei of tumors accumulate more radioactive phosphorus than normal liver nuclei. This was shown to be due to mitotic activity and not a form of metabolism peculiar to t...
متن کاملRadio-free bacteria.
In 1956 a food technologist at Oregon State University made a startling discovery: cans of meat that had supposedly been sterilized with gamma radiation contained a thriving organism, subsequently named Deinococcus radiodurans. D. radiodurans has been shown to survive and continue to function after being exposed to radiation doses up to 10 times those that would kill most bacteria. In addition,...
متن کاملRadio-isotope investigations in primary myeloid metaplasia.
Chromium-51 and iron-59 studies in patients with primary myeloid metaplasia show that the anaemia of the condition is dependent on depression of marrow activity, aggravated in about one-third of cases by accelerated red cell destruction to which the marrow compensatory response is inadequate. Surface measurements of isotope activity assist in assessing dependence on extramedullary sites for ery...
