Bioprocess separation techniques

Bioseparations engineering refers to the systematic study of the scientific and engineering principles utilized for the large-scale purification of biological products. separating the biomass (microbial cells) generally carried out by filtration or sedimentation, drying, crystallization, chromatography and centrifugation or ultra-centrifugation. If the product is biomass, then it is recovered for processing and spent medium is discarded. If the product is extra cellular the biomass will be discarded. Ultra filtration is an alternative to the centrifugation. Separation may be Solid-Liquid Separation, Liquid-Liquid Extraction, Precipitation and crystallization. purification of biomolecules generally involves the use of cross flow filtration or normal flow filtration combined with chromatographic separations. Bioprocess filtration involves Chromatographic removal of endotoxins, Laboratory filtration, Bioprocess purification and removal of cell debris, advanced chromatographic techniques for Enzyme purification, SDS-PAGE. 250 more institutes are conducting research on Bioprocess filtration. Universities offering from other part of the world. 10, 000, 00 $ funds are released in USA for year 2014. In other part of the world $ 50K were released. There are 7800 more industries working on Downstream Bioprocessing.

Biotechnology has undergone phenomenal growth in recent years. Most of this has been in fundamental areas linked to cellular and molecular biology, biochemistry and biophysics. In comparison, growth in more applied areas such as bioprocess engineering has been relatively modest, largely due to significantly lower funding in these areas, both in academia and industry. The net result of this has been the hugely inflated but largely unfulfilled expectations about the benefits of biotechnology. It is now being appreciated that symmetric growth in basic and applied areas is crucial for healthy development of biotechnology. One of the major segments within biotechnology where research and development is vital is bioprocessing which deals with the manufacture of biochemicals, biopharmaceuticals, foods, nutraceuticals, and agrochemicals. A plethora of new biologically derived products have been developed, approved and licensed in the last decade. This includes monoclonal antibodies used for the treatment of cancer and multiple sclerosis, plasmids for gene therapy, cytokines and interleukins. Many of these products need to be extensively purified before they can be used for their respective applications. Bioseparations engineering refers to the systematic study of the scientific and engineering principles utilized for the large-scale purification of biological products.
