Downstream processing and analytical bioseparation both refer to the separation or purification of biological products, but at different scales of operation and for different purposes. Downstream processing implies manufacture of a purified product fit for a specific use, generally in marketable quantities, while analytical bioseparation refers ...
A bioprocess is composed mainly of three stages—upstream processing, bioreaction, and downstream processing—to convert raw material to finished product. [11] The raw material can be of biological or non-biological origin. It is first converted to a more suitable form for processing.
The extracellular type II and type I kinase receptors binding to the TGF-β ligands. Transforming growth factor-β (TGF-β) is a superfamily of cytokines that play a significant upstream role in regulating of morphogenesis, homeostasis, cell proliferation, and differentiation. [2]
The midstream operations are often taken to include some elements of the upstream and downstream sectors. For example, the midstream sector may include natural gas processing plants that purify the raw natural gas as well as removing and producing elemental sulfur and natural gas liquids (NGL) as finished end-products.
The oil and gas industry is usually divided into three major sectors: upstream, midstream, and downstream. The downstream sector is the refining of petroleum crude oil and the processing and purifying of raw natural gas , [ 1 ] as well as the marketing and distribution of products derived from crude oil and natural gas .
Some plants also form smaller tubers or tubercules that act like seeds, producing small plants that resemble (in morphology and size) seedlings. Some stem tubers are long-lived, such as those of tuberous begonias , but many plants have tubers that survive only until the plants have fully leafed out, at which point the tuber is reduced to a ...
Downstream may refer to: Downstream (hydrology) , the direction towards the mouth of a stream, i.e. the direction the current flows Downstream (bioprocess) , when a cell mass from an upstream process (isolated, grown and harvested) is further processed to meet purity and quality requirements
"Lenticel breakdown" is a global skin disorder of apples in which lenticels develop dark 1–8 mm diameter pits shortly after processing and packing. [ 18 ] [ 19 ] It is most common on the ' Gala ' ( Malus × domestica ) variety, particularly the ' Royal Gala ', and also occurs in ' Fuji ', ' Granny Smith ', ' Golden Delicious ', and 'Delicious ...
