Immobilized CalB for Pharmaceutical Manufacturing

A proven biocatalyst for scalable, cost‑efficient and sustainable API & intermediate synthesis – enabling cleaner chemistry at commercial scale.

Immobilized CalB (Candida antarctica Lipase B) is a proven, industrial biocatalyst used at multi‑kilogram to ton scale in pharmaceutical and intermediate manufacturing. Delivered in a stable, immobilized format, immobilized CalB enables high‑selectivity esterification and transesterification reactions under mild conditions; supporting reliable scale‑up, lower cost in use, and more sustainable processes.

In partnership with enginzyme, we support pharmaceutical manufacturers and CDMOs in evaluating, implementing, and scaling immobilized CalB‑based processes as a robust alternative to traditional chemical routes.

Why Immobilized CalB for Pharma?

Designed for real manufacturing environments, immobilized CalB is already embedded in commercial API and pharmaceutical intermediate supply chains, valued for its reliability, reusability, and supply security.

Key advantages include:

  • High selectivity and consistent performance for esterification and transesterification reactions.
  • Immobilized, mechanically robust format suitable for repeated batch operation.
  • Reusability across multiple reaction cycles, reducing cost in use.
  • Stable performance in organic solvents and mixed hydrophobic/hydrophilic systems.
  • Lower operating temperatures, improving safety and energy efficiency.
  • Reduced reliance on harsh reagents, supporting greener chemistry.

Proven Performance with Immobilized CalB Technology​

High activity. High productivity. High confidence.

Immobilized CalB formulations have demonstrated:

● Over 50% higher lipase activity and productivity versus incumbent formulations
● Over 99% conversion in esterification reactions, reducing downstream purification
● Consistent performance across multiple reaction cycles, enabling reuse
● Shorter reaction times with low catalyst loadings, improving throughput

These attributes make immobilized CalB particularly well‑suited to API intermediates, chiral building blocks, and functional esters used in pharmaceutical manufacturing.

Simplifying Processes, Reducing Waste

From complex chemical routes to streamlined biocatalysis

Compared to conventional chemical esterification, immobilized CalB‑enabled enzymatic processes:

● Eliminate unnecessary downstream steps
● Reduce energy demand through milder reaction conditions
● Enable catalyst recovery and reuse
● Lower waste generation and solvent usage

This translates directly into clear ROI, reduced environmental footprint, and simpler, more robust manufacturing processes.

Built for Scale and Supply Security​

Immobilized CalB solutions are suitable from laboratory evaluation through to industrial manufacture, supporting:

● Pharma and generic API manufacturers
● CDMOs producing APIs and intermediates
● Fine chemical and pharmaceutical intermediate suppliers

Multi‑kg to ton scale supply ensures immobilized CalB can be confidently integrated into commercial manufacturing strategies.

Sustainability That Delivers Real Value​

Sustainability is not an add‑on—it is embedded in immobilized CalB‑enabled processes:

● Lower energy consumption via mild operating conditions
● Reduced waste and fewer purification steps
● Extended catalyst lifetime, improving material efficiency
● Support for green chemistry initiatives aligned with pharma ESG goals
