The first paper to report new phytotoxic effects of a liquid detergent. Before this paper, no phytotoxic effects of liquid detergents were known. The following new phytotoxic effects of the liquid detergent "Vilva" on seedlings of the higher plants, buckweat Fagopyrum esculentum and rice Oryza sativa, were discovered. At a concentration of "Vilva" 0.25 ml / L, the growth of the seedlings of F. esculentum stopped, and the elongation rate of the seedlings of O. sativa was inhibited by 22-75%.

This is a first publication to report a unique bioassay of synthetic surfactants using soil algae. Also, this is a first publication to report a juxtaposition of results of the three methods of assessment of toxicity of a chemical: the methods that use (1) plant seedlings; (2) aquatic algae cultures; (3) soil algal cultures.
Experiments investigating the effects of the cationic surfactant ( surface active compound) [exemplified by tetradecyl trimethylammonium bromide (TDTMA)] on a number of aquatic and soil algal cultures, and the seedlings of Fagopyrum esculentum are described, and the results presented. It is concluded that future studies on the effects of pollutants on algae should involve the use of several test systems (both aquatic and soil algal cultures).

It is concluded that future studies on the effects of pollutants on algae should involve the use of several test equations.
A more detailed abstract: The effects of environmental pollution with a cationic surface-active substance (surfactant tetradecyltrimethylammonium bromide TDTMA) on certain cyanobacteria and algae - cyanobacteria Nostoc muscorum Ag, strain 33 isolated from the soil in the Kirov Oblast (Region); green algae Bracteacoccus minor (Chodat) Petrova, strain 200 and strain 219 (the strain 219 was isolated from the volcanic ash collected next to Tyatya Volcano, island of Kunashir) - was investigated. Their sensitivity to that surfactant TDTMA was compared with the sensitivity of a test based on the use of terrestrial plants. The algal experiments were performed with aquatic and soil cultures. The experiments with terrestrial plants used the earlier-developed method with the seedlings of Fagopyrum esculentum Moench. The experiments revealed the higher sensitivity of the test with the aquatic algal cultures.

An innovative hypothesis that during evolution, not only endosymbiosis took place but also an additional redistribution of DNA of the endosymbionts between the nucleus and the organelles was a factor that contributed to formation of genome of a modern cell. According to the opinion of many authoritative international scientists, this hypothesis got full support in more recent publications of other authors.

In this paper, a new evolutionary model was proposed: it is postulated that portions of DNA of an ancient endosymbiotic prokaryote were transferred into the nucleus of the ancient eukaryote cell. In other words, a redistribution of DNA of endosymbionts took place. New terminology was suggested: the terms 'mitophages' and 'plastophages' ('chlorophages') were introduced in this article.
Recent publications of other authors supported this model.

ABSTRACT: This paper contributed to the proof of chemiosmotic hypothesis of Peter Mitchell, who finally received Nobel Prize (Chemistry). Eight innovations:
1. Photoinduced generation of electric current by bacteriorhodopsin, incorporated into the planar phospholipid membrane, has been directly measured with conventional electrometer techniques. 2. Two methods for bacteriorhodopsin incorporation have been developed: (a) formation of planar membrane from a mixture of decane solution of phospholipids and of the fraction of violet fragments of the Halobacterium halobium membrane (bacteriorhodopsin sheets), and (b) adhesion of bacteriorhodopsin-containing reconstituted spherical membranes (proteoliposomes) to the planar membrane in the presence of Ca2+ or some other cations. In both cases, illumination was found to induce electric current generation directed across the planar membrane, an effect which was measured by macroelectrodes immersed into electrolyte solutions on both sides of the membrane. 3. The maximal values of the transmembrane electric potential were of about 150 mV at a current of about 10(-11) A. The electromotive force measured by means of counterbalancing the photoeffect by an external battery, was found to reach the value of 300 mV. 4. The action spectrum of the photoeffect coincides with the bacteriorhodopsin absorption spectrum (maximum about 570 nm). 5. Both components of the electrochemical potential of H+ ions (electric potential and delta pH) across the planar membrane affect the bacteriorhodopsin photoelectric response in a fashion which could be expected if bacteriorhodopsin were a light-dependent electrogenic proton pump. 6. La3+ ions were shown to inhibit operation of those bacteriorhodopsin which pump out H+ ions from the La3+-containing compartment. 7. The photoeffect, mediated by proteoliposomes associated with thick planar membrane, is decreased by gramicidin A at concentrations which do not influence the planar membrane resistance in the light. On the contrary, a protonophorous uncoupler, trichlorocarbonylcyanidephenylhydrazone, decreases the photoeffect only if it is added at a concentration lowering the light resistance. The dark resistance is shown to be higher than the light one, and decreases to the light level by gramicidin. 8. A simple equivalent electric scheme consistent with the above results has been proposed.
