Efficacy of microwave against alicyclobacillus acidoterrestris in apple Juice
Apple juice inoculated with alicyclobacillus acidoterrestris was treated with microwave at different power and time, and the efficacy of microwave against alicyclobacillus acidoterrestris was investigated. The results showed that alicyclobacillus acidoterrestris quantity decreased with microwave enhancement or time extension. When juice was treated with microwave at higher than 720 W and for lo...
متن کاملCharacterization of spore germination of a thermoacidophilic spore-forming bacterium, Alicyclobacillus acidoterrestris.
The germination behaviors of spores of Alicyclobacillus acidoterrestris, which has been considered to be a causative microorganism of flat sour type spoilage in acidic beverages, were investigated. The spores of A. acidoterrestris showed efficient germination and outgrowth after heat activation (80 degrees C, 20 min) in Potato dextrose medium (pH 4.0). Further, the spores treated with heat acti...
