Abstrakt: The optimal initial volumetric oxygen transfer coefficient (KLa) was 60 h-1 for the production of β-d-galactosidase from Kluyveromyces marxianus CDB 002, using sugar cane molasses as carbon source. At this KLa applying an agitation/aeration relationship of 700 rpm/0.66 vvm resulted in 812 U l-1 h-1 for β-d-galactosidase production. This was about 50% better than a relationship of 500 rpm/2 vvm at the same KLa. [ABSTRACT FROM AUTHOR]
