etc

91
Q

Pmel requirements

A

vitamin K
hemin

92
Q

produces vitamin K

93
Q

reducing ingredients in RBAP

A

palladium chloride, L-cysteine HCL and dithiothreitol

94
Q

main enriched and selective agar

A

Laked kanamycin-vancomycin agar (LKV)

95
Q

BBE ingredients

A

96
Q

ideal anaerobic atmosphere

A

80-90% nitrogen
5% hydrogen
5-10% carbon dioxide

97
Q

how do self contained agars work?

A

Media contains enzymes which reduces oxygen in agar and space above medium
