Fermentation for APIs

Fermentation for APIs

BOC Sciences reserve strong microbial fermentation capabilities for APIs. We focus on the production and manufacturing of biological and chemical APIs via the fermentation technique. We provide pilot-to-commercial microbial fermentation capabilities, offering full support throughout the products’ life cycle. Our extensive experience and advanced fermentation technique support the development of pharmaceutical APIs.

Introduction

In the pharmaceutical industry, fermentation production of active pharmaceutical ingredients (APIs) commonly includes small molecules such as peptides, oligonucleotides, low molecular weight organic molecules, and biological macromolecules such as protein, DNA, RNA, polysaccharides, lipids and their assemblies. Microbial fermentation could be considered as the preferred solution for the production of APIs. In comparison to the synthetic chemical method, fermentation processes support the production of unique chemical molecules dependent on microorganism systems, such as antibiotics and other secondary metabolites. In addition, organic molecules are often structurally complex, including chiral centers, large stereocyclic rings, or heterocyclic systems that require multi-step synthesis to obtain. In contrast, fermentation is often a way to convert readily available raw materials such as sugars, or other inexpensive substrates into high-value products with high yields that ensure the commercial viability of high-quality products. Thus, microbial fermentation provides a more economical method for chemical APIs.

Application of Fermentation for APIs

Although microbial fermentation is not a new technology, it supports pharmaceutical companies by providing an optimal economic way to shorten the production period. Moreover, safer and more effective medicines are provided when fermentation technique is combined with current molecular biology technologies or genetic engineering tools. We believe that the continuous growth of molecular biology and synthetic biology technologies will significantly impact novel biosynthetic pathways. Microbial fermentation methods are not only used in the pharmaceutical field but also food, agriculture, biocatalytic enzymes and other fields.
