Kendomycin is an antitumor antibacterial quinone methide macrolide first isolated from the bacterium " Streptomyces violaceoruber ". 33. It was isolated from " Streptomyces pristinaespiralis " and its chemical structure was first determined in 1966. 34. Japanese microbiologist Satoshi Lmura isolated and cultured many varieties of natural soil-based bacteria from the group Streptomyces . 35. The biosynthesis of tunicamycins was studied in " Streptomyces chartreusis " and a proposed biosynthetic pathway was characterized. 36. Abundance is next to bacteria . 104-108 / g soil . 70 % of soil actinomycetes are Streptomyces . 37. Dbfirs is probably onto something with the decaying leaves which will contain " Streptomyces " that produce geosmin. 38. Thus far, gene clusters predicted to produce bottromycins have been identified in the " Streptomyces " genus. 39. Bacteria called Streptomyces are used to make most antibiotics and many other naturally produced compounds, including anti-cancer agents. 40.
