Isolation and screening of microorganisms for high yield of succinic acid production.

This study involves the isolation of succinic acid (SA)-producing microorganisms from different samples, including the rumen, sludge, soil, and wastewater. For primary screening, 29 isolates exhibited a zone of clearance around the colony, indicating acid production. For secondary screening using thin-layer chromatography, only two isolates symbolized SA production according to their R values.
