    摘要: Important intermediates for preparing cephalosporin antibiotics, 7-amino-cephalosporanic acid (7-ACA) and 7-aminodeacetylcephalosporanic acid (7-ADAC), are prepared by a novel bioprocess in which a transformed Penicillium chrysogenum strain is cultured in the presence of an adipate feedstock to produce adipoyl-6-APA (6-amino penicillanic acid); followed by the in situ expression of the following genes with which the P. chrysogenum has been transformed:1) an expandase gene, e.g., from Cephalosporium acremonium, whose expression product converts the adipoyl-6-APA by ring expansion to adipoyl-7-ADCA;2) an hydroxylase gene whose expression product converts the 3-methyl side chain of adipoyl-7-ADCA to 3-hydroxymethyl, to give the first product, 7-aminodeacetylcephalosporanic acid (7-ADAC); and3) an acetyltransferase gene whose expression product converts the 3-hydroxymethyl side chain to the 3-acetyloxymethyl side chain of 7-ACA. The final product, 7-ACA, is then prepared by cleavage of the adipoyl side chain using an adipoyl acylase. The entire synthesis, accordingly, is carried out using bioprocesses, and is efficient and economical.

    摘要: Some large software development projects need more than one versioning system to accommodate not only a diversity of document formats and data types, but also the geographic diversity of its programmers. However, having more than one versioning system is generally very expensive. A major factor in this expense is the requirement for a separate application program interface (API) for each separate versioning system. Accordingly, the inventors devised an exemplary API architecture that can be extended with “plug-in”protocol providers to include virtually any number of separate version stores or versioning systems. The exemplary architecture includes a generic command parser and a command dispatcher. The command dispatcher operatively couples to one or more protocol providers, each coupled to at least one version store. Inclusion of the OLE DB-compliant interface and the command parser in the exemplary embodiment saves the protocol providers the effort and expense of replicating these features, thereby reducing the cost of adding version stores.
