YSG Medium , 250g

Description: 

Alicyclobacillus have emerged as food spoilage organisms of major significance to the fruit juice industry (Baumgart & Menje, 2000). Spoilage is generally manifested as the formation of off flavours and odours from compounds such as guaiacol and the halogenated phenols. The economic impact of such incidents can be very high, to date, no human risk are known to be associated with the consumption of juices and other food products containing Alicyclobacillus bacteria. An acidified environment is required to grow alicyclobacilli and YSG media supports the growth of all currently known species of Alicyclobacillus (A. acidocaldarius, A. acidoterrestris, A. cycloheptanicus and A. hesperidium).

The media complies the Standard IFU Method for thedetection of taint producing organisms in fruit juices. The low pH-value of the media, in combination with the high incubation temperature inhibits the contaminating microbiota. K Agar when incubated at 45ºC supports the growth of predominantly A. acidoterrestris and limited growth of other species of the genus. Therefore, K Agar is used to detect predominantly A. acidoterrestris strains
