Molecular And Population Level Approaches To Understand Taxus Metabolism In Cell Suspension Cultures, Rohan Anil Patil

Open Access Dissertations

Plant cell culture is an attractive platform technology for production and supply of important plant derived medicinals. A unique characteristic of plant cells is the ability to grow as multicellular aggregates in suspension. The presence of these non-uniform aggregates results in creation of distinct microenvironments, which can induce variations in cellular metabolism (e.g., growth, oxygen consumption and secondary metabolite synthesis). This heterogeneity can lead to unpredictable and suboptimal performance in large scale bioprocesses. One example is the Taxus cell culture system, which produces a widely used chemotherapeutic drug - paclitaxel (Taxol ®). Despite extensive process engineering efforts which have led …
