The growth kinetics of plasmid and nonplasmid strains of 2 isogenic E. coli K12 culture lines has been studied in experiments on batch and continuous cultivation. Under the optimum conditions the growth rate of R+- and R- cells is the same; under the conditions of limited glucose supply the plasmid strains grown slower, as their energy is partly spent on maintaining plasmids in the cell.

The aim of this work was to investigate phenol decomposition by Candida tropicalis 29-10 adapted to phenol as a sole source of carbon and energy, and to elucidate the nature of resistance of continuous cultures decomposing phenol in processes with two types of control, viz. in chemostat and in pH-stat. The results suggest the resistance of the pH-stat regime of microbial cultivation during substrate inhibition. A region of instability in the chemostat cultivation has been determined when the yeast growth was inhibited with phenol.
The authors compare the effects of central electroanalgesia and premedication in hypertensive stomatological patients, administered to prepare the patients to treatment. In contrast to premedication, central electroanalgesia normalized (stabilized) the arterial pressure and pulse rate and did not reduce the rate of reaction to a light stimulus.
