| Method |
"O2 evolution measurements were performed with a
Clark-type 02 electrode (Rank Brothers, Cambridge
UK). The samples were maintained at 30°C in a water
jacketed cuvette. A 500 W light source was used to
illuminate the sample at a light intensity (1200µmoles/m^2/sec) that saturated photosynthesis." |
| Comments |
"The light-saturated rate of O2 evolution declined dramatically
in cells deprived of S for 48 h and was
reduced by about 40% in cells deprived of P for the
same period (Table 2)...The ES [energy storage] capacities presented in Table 2 represent
energy storage per unit of sample volume. The volume
of the sample that is measured in the photoacoustic
technique, as applied here, can be affected by
three parameters of the sample: its thickness, its optical
density at the wavelength of the modulated light
and its thermal diffusion properties (Carpentier et al.
1983 Tam 1986 Buschmann and Prehn 1990)." Was unable to determine how cells were counted in this study. |
