Effect of dissolved oxygen concentration on red pigment and citrinin production by Monascus purpureus ATCC 36928
(Brazilian Society of Chemical Engineering, 2008)
The present study investigated the effects of agitation speed, N (200, 500, 600 or 700 rpm), and dissolved oxygen concentration, C (120, >70, 70, 60, 10 or < 10%), on red pigment and citrinin production by Monascus purpureus ...
Effect of Process Parameters on the Progressive Freeze Concentration of Sucrose Solutions
(Chemical Engineering Communications, 2017-06-15)
The progressive freeze concentration of sucrose solutions was tested. The effect of the initial concentration of the solution (C0), the temperature of the refrigerant (T), and the stirring speed (ω) on the final concentration ...

Comparison of oxygen mass transfer coefficient in simple and extractive fermentation systems
(ELSEVIER SCIENCE SA, 2009)
Aeration and agitation are important variables to ensure effective oxygen transfer rate during aerobic bioprocesses: therefore, the knowledge of the volumetric mass transfer coefficient (k(L)a) is required. In view of ...
