1. Tushen DMPT

Dimethyl sulfide (DMS) da Polysipho - nia fastigata ke samarwa galibi yana fitowa ne dagaDMPT, wanda kuma shine mai bayar da ingantaccen methyl a cikin algae, kuma babban mai kula da osmotic na algae da shukar laka Spartina angelica ita ma DMPT ce. Abubuwan da ke cikin DMPT sun bambanta tsakanin nau'ikan ruwan teku daban-daban, kuma abubuwan da ke cikin nau'in ruwan teku iri ɗaya suma sun bambanta a cikin yanayi daban-daban. DMPT na iya hanzarta ciyarwa da haɓaka kifaye daban-daban na ruwa mai tsafta. Tasirin ciyarwa na DMPT ya bambanta da sauran abubuwa kamar L-amino acid ko nucleotides, kuma yana da tasirin ciyarwa da haɓaka girma ga kusan dukkan dabbobin ruwa.
