Membrane cell process INDEX

Many bixxer compounds contain both hydrophobic and hydrophilic sites which can alter cell membranes through penetration. There is a correlation between bitter intensity and hydrophobicity-solubility indexes such as fee octanol/water partition coefficient, lo (7). Penetration may directly affect cAMP phosphodiesterase as part of fee transduction process (see below). A bitter receptor protein may be involved wife certain bitters, such as specific structural requirements wife fee bitter tasting dipeptides and denatonium salts (27). The latter is used in some consumer products to avoid accidental ingestion. A receptor mechanism is also supported by fee existence of a genetic "taste blindness" for some bitter materials (see below). 

Thus, the processing plant by endophytic strain B. subtilis weakened the toxic effects of cadmium ions. Each strain showed itself individually. The relative and absolute tolerance indexes of plants in almost all variants were higher when seeds were pretreated with the bacteria. On the ground of the investigations of some authors and our experimental data, we suggest that the endophytic bacteria stimulate the plant growth and increase immunity, keep up the activity of catalase and peroxidase, reduce the intensity of lipid peroxidation, stabilize cell membranes with the toxic effects of cadmium. The results are of considerable interest while developing techniques for the crop production on soils contaminated with heavy metal salts.
