optimal condition for ice-nucleus production of ice nucleus bacterium included:incubation of the bacterial cells at 20～24℃ on nutrient agar containing 5% glycerol by 6 days.

Dynamic changes of ice nucleation active bacterial population inhabiting on corn in Northern China;

The biological characteristics,safety and application in food industry of ice nucleation active bacteria were summarized in this paper, moreover,its development in the future was also discussed.

The paper summarizes the recent progress in studies on cold resistance of fruit tree, including the methods in study of cold resistance, the correlation between tissue structure of organs and chilling requirement with cold resistance, the study of ice nucleation active bacteria.

mainly based on the GPI(Glycosylphatidylinositol) anchor systems of the eukaryotes,and A more systemic introduction are made on setting up themechanism of molecular organisation of lipoglycoprotein complexes of the ice nucleation protein.

The N-domain(541bp) of ice nucleation protein gene from Xanthomonas campestris pv.

The purposewas to deduce the optimal formulation of the culture medium for improving ice nucleation activity and the biomass of icenucleation-active bacteria (X.

The results showed that succinate in the growth medium had the negative function to the ice nucleation activity of Xanthomonas campestris IN 1, which was not consistent to the literature.

Ice nucleation activity and anti-leaking capability are both important technical parameters in INA (Ice nucleation active bactetia)bacteria immobilization which can be adopted on freezing concentrate.

In this paper the deactivation methods of ice nucleation active bacteria were studied.

The effects of H_2O molecules dipole polarization on ice nucleus formation and ice crystal growing under electrostatic field was investigated.
