| Abstract: | Glucose-6-phosphatedehydrogenase (EC 1.1.1.49), lactatedehydrogenase (EC 1.1.1.27), malate dehydrogenase (EC 1.1.1.38) and phosphofructokinase (EC 2.7.1.11) activities in loach (Misgurnus fossilis L.) embryos were determined after incubation of the latter in the media containing surfactants--alkyl benzol sulphonates NP-1, NP-3, RAS and secondary alkyl sulphate "Progress". The determined activities changed under the influence of the used surfactants. Minimal changes of the activities were observed in the media with sulphonol np-1, and maximal ones--with the "Progress" preparation. The dependence is revealed of the enzyme activities changes upon the surfactant concentration and the stage of the embryo development. |
