So at this time it is difficult to accurately calculate the energy and cost savings.

In your opinion which other products of the chemical and pharmaceutical industry could be efficiently produced by this technique? So far a variety of molecules have been commercially produced by microbial approaches, including bio-fuels e. In addition, the scale-up productions of many other valuable compounds are under development. The development of metabolic engineering and synthetic biology will allow microbes to produce more complicated pharmaceuticals e. Warfarin, Artimisinin, Taxol. Could this methodology, if extended to the industrial production level, be applied also to small and medium plants or the required needs could limit the SME involvement?

This technique can actually be applied in SMEs but it requires a workplace and certain equipment, like bio-reactors and separation systems.

DOI: Syntheses of 3-Acylhydroxy-2 1H quinolones. The procedure is based on a tandem C-acylation-cyclization process under mild reaction conditions. Concerning the investment, it really depends on the production scale. The production of this molecule is currently carried out by means of chemical synthesis and through the use of petroleum products, which leads to the double drawback of using a non-renewable resource and creating potentially harmful byproducts.
