Polystyrene, a synthetic polymer, is considered stable to biological degradation. Lantinus tigrinus isolated from wood sample produced esterase in growth medium under normal conditions. However, acidic medium, 37°C temperature, presence of tween 80; and urea and yeast extract in mineral salt medium strengthen production of esterase and specific activity. Purified esterase was active at broad pH range (acidic-neutral) and 45°C. FTIR analysis confirmed that esterase produced by Lantinus tigrinus effectively degraded polystyrene film and break macromolecules to non toxic molecules. This study conclude that presence of Lantinus tigrinus at dumping sites can be exploited for environmental waste management containing high molecular weight synthetic polymers.
