title: [Effect of increasing concentrations of detergents on electron transfer in chloroplasts].
abstract: The effects of increasing concentrations of sodium cholate and deoxycholate, "Tween 80" and "Triton X 100" upon O2 evolution by intact or osmotically broken spinach chloroplasts were investigated polarographically. Except for cholate, low concentrations of any detergent increased considerably (up to four times) the rates of oxygen evolution by broken chloroplasts, without interrupting the electron flux between photosystem II and photosystem I.
