Abstract

In this paper,Alicyclobacillus acidoterrestris strains were isolated from Rotten Jinshua apples and identified by morphology,physiological and biochemical experiments,and 16S rDNA molecular analysis.The effects of temperature and pH on the growth and the heat resistance on their spores were also investigated.Their optimum growth temperatures were 45℃.The optimal pH values for A-1 and A-2 were 4.0 and 3.5,respectively.The D 90℃ values of the spores generated by A-1 and A-2 were 11.90 minutes and 13.70 minutes,respectively.A-2 indicated much stronger heat resistance as compared to A-1.

Key words： apple;;Alicyclobacillus acidoterrestris;;isolation and identification;;growth characteristics
