  • Patent number: 6294669
    Abstract: As a novel substance is provided such a new, crystalline substance of Cefditoren povoxyl which has a high purity and an enhanced thermal stability on storage. This crystalline Cefditoren pivoxyl may be prepared by a process comprising a step of dissolving amorphous substance of Cefditoren pivoxyl in an anhydrous, first organic solvent capable of dissolving said amorphous substance well therein, and steps of replacing the first organic solvent component of the resulting solution by an anhydrous alkanol of 1 to 5 carbon atoms as a second organic solvent, in such a manner that the firstly prepared solution of Cefditoren pivoxyl in the first organic solvent is mixed with a volume of the alkanol and then is concentrated below 15° C. under reduced pressure, and so on. Thereby, the process proceeds so as to produce a solution containing 50 mg/ml to 250 mg/ml of Cefditoren pivoxyl dissolved in the alkanol alone.

  • Patent number: 6277596
    Abstract: A high-yield production system for proteins and peptides has been established, and especially a high-yield production system for cellulase in Trichoderma viride and similar filamentous fungi. The cellulase cbh1 gene regulator sequence derived from Trichoderma viride gives high expression of target proteins. The regulator sequence can therefore be used for high-yield expression of target proteins, especially cellulase. In particular, 15 g/L of an endoglucanase derived from Humicola insolens was successfully produced with this regulator sequence.
