    What's the difference between downstream processing

    Jun 20, 2018 The downstream processing, on the other hand, is the phase that deals with extraction or separation of desired products from the biomass (developed in upstream processing).

    with automatic solids discharge. Tangential flow (cross flow filtration) is an effective method to separate cells from liquid where high value product is involved. The parallel motion of fluid to the membrane helps reduce the thickness of the cell layer on the filter surface. Fig. 4.7: A rotary drum vacuum filter.

    Explain upstream and downstream processing in

    The upstream processing in biotechnology involves identifying and extracting the raw materials. This forms the initial process of fermentation. The upstream processing deals with: Inoculum preparation which includes screening or microorganisms and selection of suitable strain and genetic modification of the organism if needed.

    Feb 10, 2020 Cell lysis and clarification are the two obvious steps that link the Up- and Downstream Processes, and they are sometimes called Midstream Processes. Regardless of the definition, the role of Downstream Processes is to enrich the Viral Vector product while eliminating contaminants that originate from host cells and the culture medium.

    Nov 19, 2019 Another disadvantage is that as there are usually several flotation cells in series, adjustment of the outflow level valve in an upstream cell results in a disturbance in downstream cells. To overcome disadvantages related to feedback controllers, a complementary feed-forward controller can be added to significantly improve disturbance ...

    Sep 30, 2014 Blurring the Lines: Speaking of continuous bioprocessing, the lines between upstream and downstream are blurring somewhat. Although expression and harvest of a protein product stream will always mark the line between “production” and purification, the relative “batch” concepts of up- and downstream are changing.

  • What are 'upstream' and 'downstream' in fluid dynamics

    What are 'upstream' and 'downstream' in fluid dynamics

    Upstream is when you swim or float against the flow of water. Downstream is when you swim or float in the direction of the flow of the water. Say, a river flows from west to east, so if you swim in the river from east to west i.e. against the direction of the flow of the river, then you are swimming upstream.
