Biosynthesis of Indole-3-Acetic Acid by New Klebsiella oxytoca Free and Immobilized Cells on Inorganic Matrices
Figure 3
Operational stability of the free and immobilized cells of Klebsiella oxytoca on 6% SiO2/TiO2 (first cycle (white bar), second cycle (dark grey bar), third cycle (black bar), and fourth cycle (light grey bar)). Conditions: nitrogen-free malate (NFb), 100.0 μg mL−1 of L-tryptophan, pH 6.8, 28°C and 120 rpm.
