Herbicidin A is an antibiotic with selective herbidical activity against dicots. It was originally isolated from Streptomyces saganonensis in a soil sample by Sankyo (Japan) in 1976. It is the major analog of a family of adenosine-based nucleosides containing a complex tricyclic saccharide. Herbicidin A is soluble in ethanol, methanol, DMF and DMSO.
|Mechanism of Action||The mode of action and broader pharmacology of Herbicidin A has received little attention due to its restricted availability.|
|Microbiology Applications||Fermentation parameters for Herbicidin A production in submerged culture of Streptomyces scopuliridis M40 were investigated. Bioproduction was successfully scaled up from a 5-L jar to a 500-L pilot vessel (Ha et al, 2017).|
|Plant Biology Applications||Bioherbicides include phytopathogenic microorganisms or microbial compounds useful for weed control. Bioherbicides have several advantages: 1) high specificity, 2) absence of environmental residue; and 3) reduction of resistant weed populations (Hoagland RE et al, 2007).
Herbicidin A is both a herbicide against weeds affecting dicot plants and an antibiotic against phytopathogens.
