“…Over the range of variables studied in the present work the K L a L values dropped by one order of magnitude, as illustrated in Figure 7. The K L a L values reported here have been compared with the results of Schugerl et al (1977), Baker and Worgan (1981), Chisti et al (1987), Bello et al (1985a,b), and Koide et al (1985), and which are in good agreement, as illustrated in Figure 8. The exponents of correlation (13) show dependency of e GR on SF concentrations.…”

“…Therefore, the use of correlation (12) for engineering design would provide a reasonable confidence in overall volumetric mass transfer coefficient estimates. A comparison of the present K L a L result with the K L a L values reported by Baker and Worgan (1981), Bello et al (1985a,b), Koide et al (1985), and Chisti and Moo-Young (1988) is represented in Figure 8. Weiland (1981), Mann (1983), Bello et al (1985a,b) and Chisti and Moo-Young (1988), using external loop reactor (EL), stirred tank (ST), EL and central tube (CT), and CT and split design configurations of airlift bioreactors, respectively, have measured the overall, volumetric mass transfer coefficients.…”

In the present work, water and three phase compositions of Solka-Floc, a cellulose fiber for simulating the biomass in bacteria, yeast, and fungal fermentation were studied in a 1.4 m 3 stirred airlift reactor. The fractional dispersed phase holdup and the overall volumetric mass transfer coefficients were measured. The dispersed phase riser gas holdup and overall volumetric mass transfer coefficients both increased with increasing riser superficial dispersed phase velocity (0.02-0.1 ms À1 ) and agitator speed in the range of 0-5 rs À1 . An increase in the Solka-Floc concentration (1-3% w=v) was found to reduce e GR and K L a L . Empirical correlations have been developed for fractional dispersed phase gas holdup and overall volumetric mass transfer coefficients.

“…Owing to the diffuse nature of the power dissipation through the expansion of the sparging gas, these units may be used to good advantage for shear-sensitive cultures. Alternatively, researchers have utilized the airlift design for applications involving non-Newtonian broths, such as fermentation of filamentous fungi (Barker and Wogan, 1981; Malfait et al, 1981) and plant cell culture (Townsley et al, 1983). Onken and Weiland (1983) have cited other possible bioreactor applications, including the production of citric acid and xanthan gum.…”

“…Many investigations have been carried out on airlift reactors with non-viscous Newtonian systems, and recently, Chisti and MooYoung (1987) and Merchuk and Siegel (1988) have reviewed airlift reactor design and application. However few studies have been carried out on highly viscous non-Newtonian systems (Barke and Worgan, 1981;Kawase and Moo-Young, 1986;Robinson, 1984, 1987). For non-Newtonian fluids, the viscosity depends on the shear rate of movement.…”
