Streptomyces hygroscopicus is a bacterial species in the genus Streptomyces. It was first described by Hans Laurits Jensen in 1931.[3]
Biochemistry[edit]
Cultures of different strains of S. hygroscopicus can be used to produce several chemical compounds or enzymes.
Small molecules[edit]
Immunosuppressants[edit]
Sirolimus (also known as rapamycin) is an immunosuppressant that has been isolated from S. hygroscopicus from soil samples from Easter Island.[4] Ascomycin can be used to treat autoimmune diseases and skin diseases and can help prevent rejection after an organ transplant.
Antibiotics[edit]
The antibiotics geldanamycin, hygromycin B, nigericin, validamycin, and cyclothiazomycin are found in S. hygroscopicus.
Experimental cancer drugs[edit]
Indolocarbazoles can be found in S. hygroscopicus .
Anthelmintics and insecticides[edit]
Milbemycin and milbemycin oxime can be found in S. hygroscopicus cultures.
Herbicide[edit]
S. hygroscopicus also produces the natural herbicide bialaphos.[5]
Enzymes[edit]
The enzymes alpha,alpha-trehalose-phosphate synthase (GDP-forming), carboxyvinyl-carboxyphosphonate phosphorylmutase, and hygromycin-B kinase can be isolated from cultures of S. hygroscopicus.
