Azotobacter vinelandii was grown diazotrophically in sucrose-limited chemostat cultures at either 12, 48, 108, 144 or 192 gM dissolved oxygen. Steady state protein levels and growth yield coefficients (Y) on sucrose increased with increasing dilution rate (D). Specific rate of sucrose consumption (q

Live cells of a phenol-degrading bacterium, Rhodococcus sp. DCB-p0610, were immobilized on granular activated carbon (GA C) by adsorption and in alginate beads by entrapment. These immobilized particles were packed separately into two column reactors, which were used for continuous treatment of a mi
Schwanniomyces eastellii excreted e-amylase and amyloglucosidase into the medium in the presence of starch. The biosynthesis and the rate of excretion were influenced by dissolved oxygen (specially for e-amylase), pH of the culture and dilution rate. The cell yield observed (0.59) remained constant
