Summary

Controlled-release polymers containing NH4Cl were used to feed NH4+to Streptomyces clavuligerus cultures making cephalosporins in shake flasks. Production was improved in comparison to free NH4Cl included in the medium at various concentrations; it approached the performance of l-asparagine, the best single nitrogen source for production.
