Toprakta, tatl\u0131 suda, deniz ortamlar\u0131nda ve baz\u0131 organizmalarda yayg\u0131n olarak bulunur. Streptomyces, farkl\u0131 yap\u0131sal tiplere sahip \u00e7ok \u00e7e\u015fitli aktif ikincil metabolitler \u00fcretmesiyle bilinir ve klinik uygulamada yayg\u0131n olarak kullan\u0131lan antibiyotiklerin \u00f6nemli bir kayna\u011f\u0131d\u0131r.
