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 ...
The majority of the organic matter that does make its way into the system is in the form allochthonous plant material that falls into the river, such as leaves and sticks. In this section, respiration (consumption) out paces production (P/R<1). Here shredders play a major role in breaking down coarse plant material.
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.
Additionally, the biological processing of CPOM (coarse particulate organic matter – larger than 1 mm) inputs at upstream sites is expected to result in the transport of large amounts of FPOM (fine particulate organic matter – smaller than 1 mm) to these downstream ecosystems. Plants should become more abundant at edges of the river with ...
View of Amazon basin forest north of Manaus, Brazil. The term “biotic pump” infers a circulation system driven by biological processes. This concept shows forests as being the major factors in manipulating atmospheric processes to cycle rainfall taken up by trees throughout all continents and back to the atmosphere for further cycling.

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 .
Downstream migration of Atlantic salmon smolts was similarly unaffected by beaver dams, even in periods of low flows. [41] Two-year-old Atlantic salmon parr in beaver ponds in eastern Canada showed faster summer growth in length and mass and were in better condition than parr upstream or downstream from the pond.
"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 ...
