Controle da biossíntese de poli-hidroxialcanoatos bacterianos através do fluxo de substratos Control of the biosynthesis of bacterial polyhydroxyalkanoates through the flux of substrates

Química Nova, 2007
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 ...
