The uptake of Aspergillus ochraceus spores on diatomaceous particles and their use in the 11α-hydroxylation of progesterone

Biotechnology Letters Aims and scope Submit manuscript

Summary

The entrapment of Aspergillus ochraceus spores on to diatomaceous earth particles occurs rapidly, the number of spores entrapped at equilibrium being dependent upon the initial spore:particle ratio. The rate of agitation during spore uptake markedly affected entrapment. Immobilized spores carried out the 11α-hydroxylation of progesterone as effectively as free spores.
