Downstream ProcessingDownstream-processing in bioprocesses concerns the ways in which output streams (e.g. solid, liquid, slurry etc.) are handled and the means for the recovery and purification of the targeted products. It is a crucial step in bioprocess development that is often overlooked, especially in early stages of research and development, where much of the focus tends to be on optimizing the bioconversion process itself. This is a critical oversight given that downstream processing can account for a large portion (sometimes up to 80%) of the total production costs, particularly in processes dealing with dilute concentrations of the target product or complex mixtures.
Importance in BioprocessesGiving due focus to downstream processing in bioprocess development can not only lead to better product recovery and quality but also to significant cost savings and improved sustainability. This is especially important in processes concerning the valorisation of lignocellulosic feedstocks, where the complexity of the feedstock and the need for high-purity end products can make the downstream process a significant factor in the overall economic viability of the process.
BackgroundA filter press is a versatile and robust tool that is employed in many solid-liquid separation processes, an essential part of the downstream stages of bioprocesses. It involves forcing a liquid feed mixture through a series of filter plates under pressure, resulting in the separation of solid particles from the liquid phase.
