Increased Accumulation of Trehalose in Rhizobia Cultured under 1% Oxygen.
The growth of rhizobia under 1% O(2) induced the accumulation of alpha,alpha-trehalose, and the effect of low O(2) was independent of medium composition and Rhizobium species. Trehalose concentration in cells declined rapidly when microaerobic cultures were supplied with 21% O(2). Trehalose formation in nodules may be induced by the microaerobic environment.
