Analysis of the mechanism of photosynthesis by the method of intermittent illumination

Analysis of light regime in continuous light distributions in photobioreactors

“…The effect of varying light in microalgal cultures has been repeatedly addressed since long ago (Emerson and Arnold, 1932;Tamiya and Chiba, 1949). Phillips and Myers (1954) made a systematic description of a light regime based on sharp light/dark cycles, using the concepts of flash time (t f ), dark time (t d ) and light intensity of the illuminated period (I 0 ).…”

Bill Arnold's concept of solid state photosynthesis and his discoveries

“…Arnold and Kohn (1934) addressed several of these problems directly, but resistance remained. These objections were reinforced when other workers, not appreciating the crucial concept of single turnover flashes, repeated the experiments with multi ms flashes and obtained smaller ratios (Tamiya and Chiba 1949). Myers (1994) presents evidence that the star-crossed theoretician of photosynthesis, James Franck, had an 'implacable opposition' to the concept of a PSU.…”

Optimum Conditions for Photosynthesis in Optically Dense Cultures of Algae

“…For the present, the time t is left unspecified. The rate of the photosynthetic reaction per unit volume of the ^th algal cell is [5] whence from Eq. 3 one has…”

“…algal cell and let N be the number of cells present in unit volume of the culture. If we set kD = kn'Tio fCL == ">L J-io p = Nvi [15] [16] [17] then the microscopic rate of photosynthesis R v at the point where the light intensity is J is…”
