FMM containing 32 ppm (seawater) was most effective for T. maritimum and T. soleae and isolates from fish caught at sea and fish grown in saline water, although they were also able to grow in brackish water.
T. maritimum, T. soleae og bakteríustofnar einangraðir úr fiski úr sjó eða ræktaðir við seltu uxu best í æti með fullri seltu (32 ppm) en uxu þó einnig í æti með hálfri seltu (16 ppm).
