Selection of an extracellular esterase-producing microorganism
The conventional esterase plate-screening technique has been modified in order to obtain a better differentiation of high producing strains. A short exposure to Lugol's iodine solution after colony growth enhanced the contrast between the precipitation halo and the background. Batch cultures of...
