Controle da biossíntese de poli-hidroxialcanoatos bacterianos através do fluxo de substratos

Abstract

Manipulation of the flux of substrates was utilized to control the amount of 3-hydroxyvalerate and 3-hydroxy-4-pentenoate produced by Burkohlderia sp. The 3HV production rate was directly proportional to the propionic acid uptake rate with the last one completely directed to 3HV biosynthesis. The 3HPE production rate was inversely proportional to the sucrose uptake rate probably due to operation of the glyoxylate cycle.
