Bibliography

ISO/TS 11133-1:2009 provides the general terminology related to quality assurance and specifies the minimum requirements for the preparation of culture media to be used for the microbiological analysis of products intended for human consumption or animal feeding.It is also applicable to culture media to be used for the microbiological analysis of all kinds of water.These requirements are applicable to four categories of culture media used in laboratories that prepare and/or use culture media for performing microbiological analyses: commercially manufactured ready-to-use media; media to be remelted, supplemented and distributed; media prepared from commercially available dehydrated formulations; and media prepared from their individual components.
