Inhibition by Chloramphenicol of Chlorophyll and Protein Synthesis and Growth in Euglena gracilis

Abstract
SYNOPSIS. Chloramphenicol inhibits growth of Euglena gracilis. It also interferes in the “greening” process by inhibiting protein synthesis (measured by leucine uptake), but RNA synthesis is essentially unafiected. The antibiotic acts on all cell fractions, but prefermtially inhibits the synthesis of plastid protein. Inhibition of chlorophyll synthesis is transitory and does not affect the self‐reproduction system for chloroplast formation.
