Publication number: 20030045701Abstract: The invention includes polynucleotide constructs that contain a polynucleotide promoter sequence from the phosphoglycerate kinase 1 (pgk1) gene from Rhizopus oryzae. The invention also includes methods of expressing a polypeptide in a host cell using a polynucleotide construct containing a 3-phosphoglycerate kinase (pgk) gene promoter sequence operably linked to a polynucleotide encoding a polypeptide of interest. The invention also includes a system for producing a polypeptide. The system has a first polynucleotide sequence containing a 3-phosphoglycerate kinase gene promoter sequence isolated from a fungal species, and a second polynucleotide sequence which has been isolated from a second species and which encodes a polypeptide. A host cell contains the first polynucleotide sequence operably linked to the second polynucleotide sequence. The host cell is from a different species than the fungal species from which the first polynucleotide sequence is isolated.Type: ApplicationFiled: August 7, 2002Publication date: March 6, 2003Inventors: Johnway Gao, Daniel B.

Patent number: 4417415Abstract: Porphyridium cruentum is cultured in an enriched seawater medium using a high initial cell concentration until the productivity of polysaccharide production by the alga is maximized. The whole culture is then extracted by making the culture strongly alkaline, and heat treating it. The culture is cooled, acidified and the polysaccharide precipitated by addition of a water-miscible organic solvent such as ethanol. Very high yields of polysaccharide are obtained, in excess of 4.5 grams per liter of culture.Type: GrantFiled: April 26, 1982Date of Patent: November 29, 1983Assignee: Battelle Development CorporationInventors: Gerry R.
