Substitute for agar in solid media for common usages in microbiology.
The potassium salt of carrageenan was found to be an adequate replacement for agar in solid bacteriological media. The common microbial genetic techniques, such as purifying colonies by streaking, replication tests, and titration of cultures, were carried out sucessfully with a number of mutant strains of Escherichia coli.
