Figure 1.
MIPS functional analysis of the differently expression genes (data from Table S1) at 12 h (A) and 18 h (B).
The prominent part of the circle represents the down-regulated genes, and the other part represents the up-regulated genes.

Effect of xanthine on adenosine production and concentration of xanthine over the time course of the fermentation process.
(A) Effect of xanthine on adenosine production. The blue symbol denotes sufficient xanthine supply in the fermentation process. The red symbol denotes no xanthine addition in the fermentation process (B) Xanthine concentration over time course of the fermentation process under different DO levels.
