ABSTRACT:
This invention relates to a whole cell support and a method of preparing the support. The support comprises alumina and diatomaceous earth characterized in that the support has interconnected pores which are at least 5 microns in diameter and preferably has a pore volume greater than about 0.3 mL/g. The support is prepared by forming a mixture of an aluminum sol and a diatomaceous earth forming spheres from the mixture by using the oil drop method and then calcining at a temperature of about 1000.degree. to about 1450.degree. C.
