Abstract: A stereoselective reduction of compound II to compound of formula I ##STR1## which comprises adding ketone substrate II to a culture broth of the Zygosaccharomyces bailii ATCC 38924, incubating the resulting mixture, and isolating a hydroxy compound of formula I, is described. The resulting compound of formula I is useful as an intermediate in the preparation of 1-(4-fluorophenyl)-3(R)-[3(S)-hydroxy-3-(4-fluorophenyl)propyl]-4(S)-(4-hy droxyphenyl)-2-azetidinone which is a serum cholesterol lowering agent. Also described is a stereoselective reduction of a compound of formula IV to compound of formula III ##STR2## using Schizosaccharomyces octosporus ATCC 2479.

Abstract: Biological material is entrapped in a hydrophilic gel by using an apparatus containing a biphasic spray head. In a preferred embodiment, mammalian cells are mixed with a solution of alginate to form a mixture and the mixture is fed to a biphasic spray head where the mixture passes through a nozzle surrounded by an annular passageway through which air is passed. Droplets of the mixture are formed at the tip of the nozzle and air passing through the passageway frees the droplets from the tip and propels them into the atmosphere in the form of fine spherical droplets. The droplets then contact a solution of divalent cation such as calcium chloride which gels the alginate. Preferably, the nozzle has an inner diameter of between about 0.006" and 0.016" and is beveled at an angle between about 15.degree. and 30.degree. to form a conical tip.
