CHANGES IN THE CARBOHYDRATE AND LIPID-COMPOSITION OF THE MYCELIUM OF CUNNINGHAMELLA-JAPONICA DURING PROLONGED HIGH-TEMPERATURE STRESS

During nonlethal high-temperature stress, changes occur in the metabol ic processes of Cunninghamella japonica, which are of a cyclic nature and occur in the form of ''ups'' and ''downs.'' Such changes are noted in the intensity of the growth processes, in the accumulation of gluc ose, the composition of the membrane lipids, and the ratio of the glyc o- and phospholipids. It was found that in a stressed fungus culture n ot only the trehalose content but also the glucose content is increase d. It was shown that the accumulation of trehalose under stress is sti mulated by the addition of cycloheximide, and its synthesis is control led at the posttranslation level.
