Culture broth for gram-positive bacteria

A culture broth for culturing Gram-positive bacteria, comprising:

• a beef extract;
• casein hydrolysate;
• catalase derived from bovine liver and having an activity of at least 2,000 units/mg;
• a nonionic surfactant;
• and
• starch,
• wherein,
• the culture broth is capable of cultivating Streptococcus, Staphylococcus spp., and Enterococcus spp.,
• the culture broth comprises:
• 0.01 to 1 parts by weight of the beef extract,
• 0.1 to 5 parts by weight of the casein hydrolysate,
• 0.001 to 0.075 parts by weight of the catalase,
• 0.001 to 0.03 parts by weight of the nonionic surfactant, and
• 0.01 to 1 parts by weight of the starch,
• based on 100 parts by weight of the culture broth,
• the nonionic surfactant and catalase are present at a weight ratio from 0.2 to 10,
• the culture broth does not contain blood and/or lysed blood, and the culture broth is capable of cultivating Streptococcus pneumoniae, Staphylococcus spp., and Enterococcus spp.
