title: [Effect of temperature and the active acidity of the medium on the metabolism of reserve carbohydrates and the survivability of baker's yeast].
abstract: The effect of the cultivation temperature and active acidity of the medium on the contrent of trehalose and glycogen in baker's yeast was investigated. With the temperature growth from 20 to 40 degrees C the trehalose content in the cells increased, thus enhancing survivability of yeast during storage. The same results were observed upon temperature rise at the end of cultivation. pH of 4.5-5.0 intensified the synthesis of both reserve carbohydrates in baker's yeast.
