Casamino Acids medium (CasA)

Casamino acids are a mixture of amino acids that potentially enhance growth. The composition is known since 1971[1]. The exact composition including the recommended supplementation as described in ‘Amino Acids and Growth Factors in Vitamin-Free Casamino Acids’[1] was used for the following in sillico definition.
