[Technique for the determination of the quantum yield of the primary process in the course of photosynthesis energy transformation. III. Experimental data obtained for different photosynthetic organisms].
A relative method in two modifications has been developed for determination of the quantum yield of primary photosynthesis energy conversion. The purple bacteria E. chaposhnikovii and Chr. minutissimum, R. rubrum chromatophores, cell extracts of E. shaposhnikovii, Rps. spheroides strains GA and R-26, pigment-protein complexes from green bacterium Chl. limicola and light subchloroplast particles, enriched in the photosystem I, were investigated. The quantum yields for all these objects were shown to be 90-98%. The accuracy of the relative method used is very high (within 2--4+). The photosynthetic units were proved to be of a multicentral type for all these systems. The quantum yield values permit estimation of the coefficient of efficiency of the primary  conversion process as being approximately equal to 35-38% for bacteria and approximately equal to 50% plants.
