Effect of formation of flocculent precipitate in liquor on medium characteristics

This work investigated effect of flocculent precipitate in liquor on medium characteristics by using ethyl palmitate as inducer. The conductivity and fluorescence intensity of solution pre- or post- precipitating were respectively detected at different alcohol concentrations and temperatures. The results reveal that the solution conductivity after precipitating was maximal,then that of pre- precipitated solution,the conductivity of the control was lowest. Meanwhile,the fluorescence intensity of the control solution was more than that of the precipitated solution,and it was the lowest for the pre- precipitated solution. This work indicated that the formation of organic flocculent which had obvious effect on liquor characteristics was influenced by temperature and alcohol concentration.
