Abstract :
Bacterial production of SCP have a significant advantage over other microorganisms. Single cell protein is
the total protein extracted from the bacterial cultures. Apart from the nutritional benefits of single cell protein, single
cell protein technology is sustainable technology. Prototroph’s have high protein content with essential amino acids
and less amounts of nucleic acids. PNSB are highly resistant to toxicants and contain 70-72% of crude protein. The
composition of essential amino acids of these bacteria is similar to that of soyabean proteins. The application of
PNSB has been used to convert to hydrogen gas (Liao, 2010) or by products such as single cell proteins. PNSB
biomass is useful for fish feeding as it is rich in proteins. An in-depth analysis of the single cell production abilities
of PNSB show that the purple non sulphur bacterium Rhodopseudomonas palustris would be best in terms of single
cell protein production.
