Wallemia mycotoxin

I came across an article on a mycotoxin, walleminol A (CAS No. 126039-09-6), produced by Wallemia spp.   This fungal organism is often found in straw in agricultural settings.  In buildings it is often found on carpet near pop machines as it does well in areas with high amounts of sugar.  It does not grow very well on MEA.  It grows better on DG-18 media.  It can grow on a wide range of water activity down to .69 .
