Bacterial strains YM16-303T and YM16-304T were isolated from a sample of seashore sand using a medium with an artificial seawater base. Both isolates grew slowly on marine agar, and were found to be Gram-reaction-positive, aerobic, non-motile and rod

Total synthesis of (±)-thallusin was achieved using Hg(OTf)2·PhNMe2-induced olefin cyclization, and Suzuki coupling with a pyridylboronic acid derivative. Hg(OTf)2 also acted as a catalyst to isomerize the double bond into the more thermodynamicall
