Der Laborkleinfermentor LF2 – Physikalische Kenndaten, Beurteilung der Originalkonfiguration und Charakterisierung spezieller Ausrüstungsvarianten

Abstract

The stirred laboratory scale fermenter LF2 is a powerful device for fermentations with up to 3 liters culture broth [1]. It was designed in the Academy of Sciences of the C.S.S.R. and has found a rather wide application in a great number of organizations working in the fields of biotechnological education, research and industry in the G.D.R. and the C.S.S.R.The LF2‐fermenter is well suitable for carrying out a broad manifold of aerated biotechnological works without contaminations in basic research and process development.The mechanic and electronic design gives a lot of room for the realization of special equipment variants like special‐shaped reactor vessels or special electronic moduls for automatic control.

Bioprocess Technology

“…These systems provide more information on the mixing conditions of bioreactors than do purely physical measurements {Cleland et al, 1984;Griot et al, 1986;Karrer, 1978;Kling and Moser, 1986;Moes et al, 1984}. Also, research on the shear force effects is carried out with the help of a physical {e.g., Grosse et al, 1985} or a biological test system, Tetrahymena pyriformis {Midler and to study the damage to cells; Pullularia pullulans is a shear-sensitive biological system. Reuss (1977) presented a quantification of this effect on the basis of 112 3.…”
