Downstream in the industrial process involves refining and processing raw materials, as well as marketing and selling final products. This segment is closer to end consumers and often deals with the tangible products they use. Upstream, on the other hand, is focused on the initial stages of prod...
Such a framework including upstream and downstream processes, besides comparison of atmospheric and pressurized anaerobic digestion, with in-depth economic analysis, configures the main novelties of this work. Resource utilization efficiency metrics point advantage of pressurized anaerobic digestion case, ...
The present study describes the enhanced production and purification of lovastatin by Aspergillus terreus in submerged batch fermentation. The enhancement of lovastatin production from A. terreus was attempted by random mutagenesis using ultraviolet radiations and nitrous acid. UV mutants exhibited increased...
This work reviews current achievements and bottlenecks in upstream and downstream processing of recombinant IgA from a biotechnological point of view. We also highlight recent accomplishments with diverse expression systems and presents different affinity techniques for the capture of recombinant IgA to ...
Single-use solutionshave been used in both upstream processing and downstream processing. In addition to offering benefits in filtration and sampling, they can help reduce the risk of contamination. Thanks to its process flexibility, single-use technologies foster process optimization, serve process opti...
In contrast, most downstream flows go into dollars and euros. 相反,大部分顺向流则涉及卖出美元和欧元。 Cable is not symmetrical,downstream speeds far outpace upstream speeds. 线缆是不对称的,下行速度远远快于上行速度。 The construction of a dam influences downstream channel stability in two ways. ...
Cell behaviour is strongly influenced by physical, mechanical contacts between cells and their extracellular matrix. We review how the transcriptional regulators YAP and TAZ integrate mechanical cues with the response to soluble signals and metabolic pat
The use of continuous downstream processing may present several other advantages to the process, such as faster processing, lower resin requirements, consistent product quality, reduced costs, and easy integration to continuous upstream processes. The advances in the development of tools for improving ...
Between the upstream and downstream operations, midstream activities include storage, processing, and transportation of petroleum products. What Is an Integrated Oil and Gas Company? Integrated oil and gas companies operate in multiple streams. They may have drilling operations, refineri...
