Biosynthesis of Indole-3-Acetic Acid by New Klebsiella oxytoca Free and Immobilized Cells on Inorganic Matrices
Figure 2
Initial biomass effect on IAA production by immobilized cells of Klebsiella oxytoca on 6% SiO2/TiO2 and 10% SiO2/MnO2 matrices ((white bar) 0.3 g, (grey bar) 0.6 g, and (black bar) 1.2 g of immobilized cells). Conditions: nitrogen-free malate (NFb) medium, 1000.0 μg mL−1 of L-tryptophan, pH 6.8, 28°C, and 120 rpm.
