Determination of Bioavailable Fe in Lake Erie Using a Luminescent Cyanobacterial Bioreporter
Low Fe bioavailability has been suggested as a potential constraint on primary production in the Great Lakes. Here we report on the use of a cyanobacterial bioreporter to assess available Fe in Lake Erie during summer and fall field seasons in 2001–02. Bioreporter luminescence was derived from a luciferase reporter controlled by iron-responsive promoter element isiAB. Filtered (< 0.2 μm) water ...

متن کاملPhysiological Characterization of a Synechococcus Sp. (cyanophyceae) Strain Pcc 7942 Iron-dependent Bioreporter for Freshwater Environments
The complex chemical speciation of Fe in aquatic systems and the uncertainties associated with biological assimilation of Fe species make it difficult to assess the bioavailability of Fe to phytoplankton in relation to total dissolved Fe concentrations in natural waters. We developed a cyanobacterial Fe-responsive bioreporter constructed in Synechococcus sp. strain PCC 7942 by fusing the Fe-res...
متن کاملFe bioavailability from Fe-enriched yeast biomass in growing rats.
The Fe content in animal feeds is highly variable. The availability of Fe in feeds varies with the feed and the form in which Fe is present. The present study reports the effect of the addition of different concentrations of Fe from yeast biomass on Fe bioavailability and Fe level in rat liver, compared with a diet containing Fe-sulphate (Fe-sulphate) addition (control) and with a diet without ...
متن کاملThe effect of bicarbonate on iron (Fe) and zinc (Zn) uptakes by soybean varieties
Bicarbonate anion, has a very high concentration in the calcareous soil, and in fact, is the main cause of chlorosis in calcareous soils. This study was conducted to evaluate eight soybean cultivars with iron deficiency and bicarbonate presence. The present research was carried out with the aim of assessing the effect of irrigation with water containing bicarbonate on enzyme activities and Fe a...
