Alicyclobacillus spp.
一般描述
Alicyclobacillus is a food-spoiling microorganism and requires an acidic environment to grow. YSG media supports the growth of all currently known species of Alicyclobacillus (A. acidocaldarius, A. acidoterrestris, A. cycloheptanicus, and A. hesperidium). The low pH value of the media, in combination with the high incubation temperature, inhibits the growth of contaminating microbiota. K Agar, when incubated at 45ºC, predominantly supports the growth of A. acidoterrestris and limits the growth of other species of the same genus. Therefore, K Agar is mainly used to detect A. acidoterrestris strains.
应用
M-YSG Broth is used for the detection and enrichment of Alicyclobacillus, in fruit juices and other acidic foods.
