Ikhtisar

Penicillin G (benzylpenicillin) is produced by submerged aerobic fermentation of Penicillium chrysogenum in large-scale stirred-tank bioreactors. Since Alexander Fleming's 1928 discovery, industrial production has been refined to achieve yields over 50 g/L through strain improvement and process optimization. The fermentation typically runs for 6-8 days, followed by extraction, purification, and crystallization. Penicillin G serves as a direct therapeutic agent and as the starting material for semi-synthetic penicillins.

Proses Kimia

Penicillium chrysogenum is cultivated in 100,000-200,000 liter bioreactors with continuous feeding of glucose and phenylacetic acid as the side-chain precursor. The broth is filtered, extracted with butyl acetate at pH 2-2.5, and crystallized as the potassium salt.

L-Cysteine + L-Valine + Phenylacetic acid → Penicillin G (enzyme-catalyzed biosynthesis via ACV synthetase, isopenicillin N synthase, and acyltransferase)

Bahan Baku

  • Glucose (C₆H₁₂O₆) — Corn wet milling (Carbon source)
  • Phenylacetic acid (C₈H₈O₂) — Chemical synthesis (Side-chain precursor)
  • Corn steep liquor — Corn wet milling byproduct (Nitrogen source)

Produk Akhir

  • Penicillin G potassium — Injectable antibiotic and semi-synthetic penicillin precursor (>98% purity by HPLC)
  • 6-APA (6-aminopenicillanic acid) — Core structure for semi-synthetic penicillins (Derived by enzymatic cleavage)

Environmental Impact

Fermentation generates large volumes of mycelial waste and spent broth requiring treatment. Solvent extraction with butyl acetate produces VOC emissions. Modern facilities use solvent recovery and waste biomass composting to reduce environmental impact.

Pertimbangan Keselamatan

Inovasi Terbaru

Metabolic engineering of Penicillium strains using CRISPR-Cas9 has further improved yields.
Continuous chromatography purification is replacing traditional solvent extraction to reduce chemical waste and improve product quality.
