Camptotheca acuminata plants contain camptothecin which is a secondary metabolite with strong anti-tumor activity. The induction of callus and cell suspension cultures from Camptotheca acuminata stem parts on different media is described. Growth in t

Nocardia erythropolis cholesterol oxidase catalyzes two distinct reactions: the oxidation of a 3-hydroxy-Δ5-steroid to a 3-keto-Δ5-derivative followed by the isomerization to a 3-keto-Δ4-steroid. As this enzyme has potential applications in steroi

The influence of agitation rate on Xanthan production in a baffled stirred tank reactor is reported. To separate the hydrodynamic effect of agitator speed on any slime layer from the influence on oxygen mass transfer, oxygene-enriched air was used. F
