Photosynthetic membrane development in Rhodopseudomonas spheroides: Incorporation of bacteriochlorophyll and development of energy transfer and photochemical activity
(Elsevier, 1969-10-21)
1. 1. Bleached cells of Rhodopseudomonas spheroides, obtained by aerobic growth in the light, rapidly synthesize bacteriochlororphyll and carotenoids when transferred to 4% oxygen in the dark. Fluorescence excitation spectra ...
Semipermeable ion-exchange membranes as a preconcentration matrix for trace analysis by electrochemical and neutron-activation techniques
(Elsevier, 1969-01)
Ion-exchange membranes were used in conjunction with neutron-activation analysis and anodic stripping voltammetry for the determination of certain trace metal ions. The various parameters which govern the applicability, ...
