Purification of shikimic acid from fermentation broth the fermentation broth (1100-1200 ml) was centrifuged at 14000g for 20 min and the cells were discarded. Microbial fermentation for the production of shikimic acid is evolving as a promising technique for large scale production these processes mostly involve metabolically engineered. Shikimic acid is a key intermediate for the synthesis of the antiviral drug oseltamivir (tamiflu®) shikimic acid can be produced via chemical synthesis, microbial fermentation and extraction . The scientists describe a new process for making the drug that does not use shikimic acid they found that d-ribose, a naturally-occurring sugar produced by fermentation in large scales, potentially provides an inexpensive and abundant source of starting material for making the drug.

Production of shikimic acid by fermentation has many advantages over the plant sources, owing to its simplicity and easy availability of shikimic acid at the time of . Microbial production of shikimic acid, a precursor of neuraminidase inhibitor- antiviral drug fermentation of shikimic acid. The shikimic acid pathway, ubiquitous in microorganisms and plants, provides precursors for the biosynthesis of primary metabolites such as the aromatic amino acids and folic acid several branchpoints from the primary metabolic pathway also provide aromatic and, in some unusual cases, nonaromatic .
