Methodology applied for product recovery depends upon when and where the product is formed, the purity of the product, use of the product, impurities that are present within the broth, price of the product and so on. âWhenâ is applicable for, with which phase of the cell cycle the product is formed and âwhereâ is applicable for, whether the product is intra-cellular or extra-cellular in its formation. Product recovery cost mainly guides the cost of the product in the market. More investment towards product recovery increases the cost of the product in the market. Even purity of the product and intended use of the product will increase the investment towards product recovery and purification. Various techniques involved in product recovery are filtration, centrifugation, precipitation, dialysis, solvent extraction, chromatographic and electrophoretic techniques, crystallization techniques etc. Products which is extra-cellular, need filtration of spent broth directly and if the product is intra-cellular, then the cells need to be lysed either by sonication or by centrifugation methods and then the resultant product is subjected to filtration and other purification techniques. As we get our resultant filtrate, then this filtrate is subjected for the rest of the purification process. Sometimes the investment we put towards purification also depends on, whether the product needs to be partially purified or completely purified. In this way, the desired product after its purification techniques done will be in its finalised form which is to be packed accordingly and then need to be marketed.
Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
