Resistance of Streptomyces cinnamonensis to butyrate and isobutyrate: production and properties of a new anti-isobutyrate (AIB) factor.

Journal of general microbiology - 1 Sept 1991

Pospísil S

Abstract excerpt

Butyrate and isobutyrate (after isomerization to n-butyrate) are specific precursors for the biosynthesis of monensin A in Streptomyces cinnamonensis. High concentrations of both butyrate and isobutyrate (greater than 20 and 10 mM, respectively) were toxic to S. cinnamonensis plated on solid medium. Spontaneous mutants resistant to these substances were isolated. These new strains produced monensins at even...
