Operação ótima de reator para síntese enzimática de ampicilina com cristalização simultânea dos produtos
(Universidade Federal de São Carlos, 2007-03-05)
Nowadays, industrial production of semi-synthetic penicillins requires low
temperatures, organochloride solvents and yields a great amount of non-recyclable wastes.
During the last decades, concerns about environmental ...
Influência da linhagem da levedura e das condições de cultivo no processo de isomerização e fermentação simultâneas da xilose
(Universidade Federal de São Carlos, 2013-03-21)
The conversion of the hemicellulosic fraction in ethanol is a factor that impacts on the economic viability of the second generation ethanol production process from sugar cane bagasse. Hemicellulose from bagasse is a ...
