Surfactants of the type 1-alkyl-1-ethylpiperidinium bromides (C6 - C18) and 1-alkylpiperidine-N-oxides (C8 - C18) inhibited growth and chlorophyll synthesis in the green algae Chlorella vulgaris as well as they inhibited Hill reaction activity in spinach chloroplasts. Their inhibitory activity was strongly dependent on the length of the surfactant alkyl chain. The algicidal effect of studied surfactants was manifested in the concentration range of 4.2x0.01 M to 1.0x0.00001 M. Electron spin resonance (ESR) spectra of spinach chloroplasts demonstrated that the studied surfactants affected the structure of photosystem (PS) 2 and the electron transfer to PS 1.
