Graphical Abstract
  • that are accompanied by a broad range of headspace constituents that occur in many actinomycetes. Volatiles might be of ecological importance for the producing organism, and, as biosynthetic intermediates or shunt products, they can be useful as indicators of antibiotic production in a bacterium
  • . Keywords: headspace analysis; natural products; polyketide biosynthesis; pyridine derivatives; streptazolin; volatile compounds; Introduction Actinomycetes are excellent producers of diverse and bioactive secondary metabolites. These metabolites belong to many different structural classes including
  • polyketides, nonribosomal peptides, terpenoids, alkaloids, lipids and others. Such compounds became a major source of biologically active natural products as antibiotics, cytotoxic compounds, immunosuppressants etc. In addition, actinomycetes are also able to produce and release a wide variety of volatile

  • , but the overall trend is similar, and therefore chlorine and bromine are also the most widespread halogens in natural products from terrestrial organisms. Many biologically active halogenated secondary metabolites are known from actinomycetes including vancomycin [4], chloramphenicol [5], rebeccamycin

  • for actinomycetes in contrast to standard plate covers with air-permeable foils. A 3 mL volume of TSB was inoculated with a 0.5 cm × 0.5 cm agar slice of a sporulating petri-dish culture and cultivated for 48 h at 30 °C. The main culture consisting of 3 mL SM3 [45] complemented with feeding-buffer

  • for internal methyl branches in various chain positions, while the methyl ester function is derived from S-adenosyl methionine (SAM). Keywords: actinomycetes; FAMEs; fatty acid biosynthesis; GC–MS; volatiles; Introduction Lipids in general, and particularly fatty acids (FAs), belong to the most
  • -methylpentanoate (5), methyl isocaproate (6), and methyl 3-methylpentanoate (7) were found in actinomycetes [11][12]. Methyl 9-methyldecanoate (8) is released by the myxobacterium Stigmatella aurantiaca DW4/3-1 [13]. A complex mixture of several methyl 2-methylalkanoates (9–26) was recently reported from the
  • gliding bacterium Chitinophaga Fx7914 [14]. Some α,β-unsaturated FAMEs have also been described, such as methyl 4-methylpent-2-enoate (27), methyl tiglate (28), and methyl 3-methylcrotonate (29) from actinomycetes [12], and various methyl 2-methylalk-2-enoates (30–43) from Chitinophaga [14].

  • ; structure determination; Introduction Marine microorganisms are widely recognized as rich sources of novel natural products [1][2]. In recent years, numerous novel compounds discovered from marine actinomycetes have been reported [3][4][5]. During the course of our search for biologically active substances
  • from marine derived actinomycetes, a strain of the genus Streptomyces was isolated from deep sediment collected from the west Pacific. Herein, we report the isolation and structure determination and biological properties of three new polyketides, namely phaeochromycins F (1), G (2) and H (3), from
