Chiral amines are important building blocks for the synthesis of bioactive molecules, and efficient and environmentally benign methods are required for their preparation in high yield, productivity, product concentration and enantiomeric purity (Höhne and Bornscheuer 2009).
Simulated moving bed (SMB) technology is a continuous chromatographic technique proven to have many advantages compared to conventional batch chromatography, such as: raised productivity and product concentration, reduced buffer consumption as well as more efficient use of raw material.
Optimization of the in situ product recovery process will lead to further increase of product concentration and productivity.
The main hindrances have been low productivity, low final product concentration, slow growth, high end-product inhibition, and costly downstream separation from sub-products (Blanc and Goma 1987; Goswami and Srivastava 2001).
The main hindrances have been low productivity, low final product concentration, slow growth, high end-product inhibition, and costly downstream separation from sub products [ 8, 9].
For biotechnological production of R-HAs on a large scale, it is important to not only consider yield, product concentration, and productivity, but also the cost of substrates and downstream processing, which are crucial constraints for a process to become economically viable.
Kids would be short-changing themselves in terms of production, concentration and productivity if they try to do brain work on an empty stomach".
This could significantly increase the product yield, productivity, and concentration and hence reduce the production costs.
Integration of bioreactors with these energy-efficient separation methods could significantly increase the product yield, productivity and concentration and hence lower the production cost.
The results suggested that increasing PPFD significantly enhanced biomass production in terms of productivity, biomass concentration, and total dry weight at both harvest ratios.
