Abstract: The present invention relates to a novel cytochrome P450-like enzyme (Aspergillus ochraceus 11 alpha hydroxylase) and an oxidoreductase (Aspergillus ochraceus oxidoreductase) isolated from cDNA library generated from the mRNA of Aspergillus ochraceus spores. When the cDNA encoding the 11 alpha hydroxylase was co-expressed in Spodoptera frugiperda (Sf-9) insect cells with the cDNA encoding human oxidoreductase as an electron donor, it successfully catalyzed the conversion of the steroid substrate 4-androstene-3,17-dione (AD) to 11 alpha-hydroxy-AD as determined by HPLC analysis. The invention also relates to nucleic acid molecules associated with or derived from these cDNAs including complements, homologues and fragments thereof, and methods of using these nucleic acid molecules, to generate, for example, polypeptides and fragments thereof. The invention also relates to the generation of antibodies that recognizes the A.

Abstract: A method of separating enantiomeric lactam esters. The lactam esters are contacted with a biocatalyst, such as an enzyme or a microorganism, in a solution wherein only one enantiomer is selectively hydrolyzed to give the optically active isomer of the corresponding acid. The hydrolysis product is then separated from the unreacted lactam esters. The enzyme is then recycled for reuse in the next enzymatic resolution. The undesired isomer is also racemized and reused in the next enzymatic resolution.

Abstract: A method and apparatus for dewatering an aqueous coal slurry includes imparting high shear forces to the aqueous coal slurry in the presence of a peptizing agent to render coal particles hydrophobic by stripping clay from the coal particles and peptizing the clay in the aqueous medium of the slurry. The slurry is separating to recover coal particles and the aqueous medium is draining medium from the hydrophobic surface of the coal particles.
