摘要：
Diacetyl production by (Citr*)Lactococcus lactis subsp. lactis 3022 was found to be an oxygen-dependent reaction. The diacetyl production by the cells immobilized in conventional Ca-alginate gel beads (Diameter: 3 mm) was lower than that of the cells immobilized in Ca-alginate gel fibers (Diameter: 0.2 mm), probably because oxygen transfer to the immobilized cells is better in gel fibers than in gel beads. © 1990 Science and Technology Letters.
