Abstract:
A permeabilization method of Micrococcus cells has been established. The obtained penneabilized cells could be used for several batches and in the mean time the intracellular enzymes still keep high activity. This method will undoubtedly increase the productivity of the cells and cut down the cost; therefore, it will be a promising way in the treha-lose industrialization. The experiment shows: after being treated with 5% (v/v) methylbenzene for 40min, the cells in suspension were converted into permeabilized cells, then the latter acted on 10% liquefied starch to produce trehaloae, the conversion ratio could reach 70%. The penneabilized cells could be used at least for 6 batchs (12h per batch) and the intracellular enzyme activity kept steady.
