Search for medium no. = [1294].
Unless otherwise stated, sterilize media by autoclaving at 121°C for 15 min.


Modified MJ synthetic seawater C  1.0     L
Resazurin  1.0     mg
Adjust pH to 7.0 and autoclave. After cooling, add the following solutions (filter-sterilized):
8% NaHCO3 solution  12.5     ml
Trace vitamins (see Medium No. 197)  10.0     ml
