a The cab1 mutations altered yeast capacity to overcome metal toxicity. Solid growth assays were performed with the yeast strains described above in glucose media supplemented with 7 mM FeSO4 or with 10 mM CuSO4. The representative images are from two independent experiments, each performed in...
Why does a sodium street lamp give off a yellow color, whereas a neon light gives off a red color? What is it that makes the FeSO4 solution turn out blue in color? Why are [ C o ( N H 3 ) 5 C l ] C l 2 named as pentaaminechloroCOBALT(iii)chloride but not pentaaminechloro...
These agents can be divided into the following categories according to the different uses in the sludge press filtration treatment: Flocculant: sometimes called coagulant, it can be used as a means to strengthen solid-liquid separation, used in primary sedimentation tank, secondary ...
B, buffer-subtracted absorbance spectra of purified YecA (solid black), purified YecA that was dialyzed against EDTA (dash-dot), and EDTA-dialyzed YecA to which an equimolar concentration of FeSO4 was added (dashed). The absorbance spectra were normalized to the concentration of YecA. C, the ...
