Secretion of Aspergillus oryzae alkaline protease in an osmophilic yeast, Zygosaccharomyces rouxii.

To produce Aspergillus oryzae alkaline protease (Alp) in an osmophilic yeast Zygosaccharomyces rouxii, we constructed an expression plasmid consisting of the Z. rouxii glyceraldehyde-3-phosphate dehydrogenase (GAPDH) promoter, the prepro-Alp cDNA of A. oryzae, the whole sequence of Z. rouxii plasmid pSR1, and the G418 resistant gene. The resulting plasmid, when introduced into Z. rouxii cells, ...

Isolation and characterization of the alkaline protease gene of Aspergillus oryzae.

The genomic DNA for the alkaline protease (Alp) of the fungus Aspergillus oryzae was isolated using synthetic oligonucleotides as hydridization probes, and the complete nucleotide sequence was identified. The Alp gene is 1374 nucleotides long and contains three introns, one of which is in the pro region and two in the mature coding region. Sequences related to the TATA box (TATAAAT) and the CAA...

Draft Genome Sequencing of the Highly Halotolerant and Allopolyploid Yeast Zygosaccharomyces rouxii NBRC 1876

The highly halotolerant and allopolyploid yeast Zygosaccharomyces rouxii is industrially used for the food production in high concentrations of salt, such as brewing soy sauce and miso paste. Here, we report the draft genome sequence of Z. rouxii NBRC 1876 isolated from miso paste.

Thermostable alkaline protease produced by an Aspergillus niger strain

A thermostable alkaline protease was isolated from the Aspergillus niger Z1 strain in a liquid Czapek Dox medium, containing casein (1% w/v) as the sole nitrogen source. Enzyme extract was subjected to electrophoresis in SDS-polyacrylamide gel. Two protein bands were seen on polyacrylamide gel. Active enzyme was visualized in a zymogram and protease activity exhibited a molecular mass of 68 kDa...

An obligate osmophilic yeast from honey.

An obligate osmophilic yeast that requires high sugar concentrations (10 to 20% glucose) for growth was identified as Saccharomyces bisporus var. mellis. Optimum growth for this strain was at 60% glucose. Several non-assimilable compounds permitted growth at glucose concentrations below the minimum requirement and stimulated growth at glucose concentrations above the minimum. No correlation exi...
