Single cell protein: Sources, mechanism of production, nutritional value and its uses in aquaculture nutrition
Abstract
Single cell protein (SCP) is a bulk of dried cells which can also termed as bioprotein, microbial protein or biomass. SCP is produced by the microorganisms such as algae, yeast, fungi and bacteria, however, fungi and bacteria are the major producers of this protein. High production of proteins from these sources was mainly due to their fast growth rate and relatively higher protein level in their chemical structure. Some algal species were also used for this purpose which specifically cultivated in the aquatic medium. In addition to high content of protein, SCP also contains carbohydrates, nucleic acids, fats, minerals and vitamins. Additionally, SCP has a high level of essential amino acids such as lysine, methionine, and threonine. This source of protein (SCP) has been proved a good replacement of other expensive protein sources like fish and soybean meals. Therefore, conclusion can be made that SCP can easily replace traditional (plant and animal) protein sources in human, animal as well as fish diets without any detrimental effect. Finally, in this review, we focus on new feeding trials on SCP in some aquaculture species, such as Atlantic salmon, white leg shrimp and rainbow trout.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
