1	BATCH MODE		293	100 mg of thaumatin (Sigma-T7638) was dissolved in 1 ml of MiniQ water, reaching a concentration of 100 mg/ml with solutions vortexed to ensure complete dissolution. Subsequently, 200 uL of the thaumatin solution was mixed with 200 ul of 1.6 M (Na, K, tartrate) crystallization solution
