Calcium-Phosphate Combination Enhances Spinosad Production in Saccharopolyspora Spinosa via Regulation of Fatty Acid Metabolism [PDF]

Applied Biochemistry and Biotechnology, 2021
Abstract Phosphate concentration above 10 mM reduces the production of many secondary metabolites; however, the phenomenon is not mechanistically understood yet. Specifically, the problem of phosphorus limitation in antibiotic production remains unresolved.

Genes for the biosynthesis of spinosyns: applications for yield improvement in Saccharopolyspora spinosa

Journal of Industrial Microbiology and Biotechnology, 2001
Spinosyns A and D are the active ingredients in an insect control agent produced by fermentation of Saccharopolyspora spinosa. Spinosyns are macrolides with a 21-carbon, tetracyclic lactone backbone to which the deoxysugars forosamine and tri-O-methylrhamnose are attached. The spinosyn biosynthesis genes, except for the rhamnose genes, are located in a

Rhamnose biosynthesis pathway supplies precursors for primary and secondary metabolism in Saccharopolyspora spinosa. [PDF]

J Bacteriol, 2001
ABSTRACT Rhamnose is an essential component of the insect control agent spinosad. However, the genes coding for the four enzymes involved in rhamnose biosynthesis in Saccharopolyspora spinosa are located in three different regions of the genome, all unlinked to the cluster of other genes that are required ...
