Phosphomannans and Other Components of Flocculent and Non-Flocculent Walls of Saccharomyces cerevisiae

Phosphomannans and other components of flocculent and non-flocculent walls of Saccharomyces cerevisiae.

effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...

Development of stable flocculent Saccharomyces cerevisiae strain for continuous Aspergillus niger beta-galactosidase production.

A flocculent Saccharomyces cerevisiae strain was engineered to stably secrete Aspergillus niger beta-galactosidase in a continuous high-cell-density bioreactor. The delta-sequences from the yeast retrotransposon Ty1 were used as target sites for the integration of the beta-galactosidase expression cassette. High-copy-number transformants were successfully obtained using the delta-integration sy...

Development of Stable Flocculent Saccharomyces cerevisiae Strain for Continuous Aspergillus niger β-Galactosidase Production

A flocculent Saccharomyces cerevisiae strain was engineered to stably secrete Aspergillus niger β-galactosidase in a continuous high-cell-density bioreactor. The δ-sequences from the yeast retrotransposon Ty1 were used as target sites for the integration of the β-galactosidase expression cassette. High-copy-number transformants were successfully obtained using the δ-integration system together ...

Behaviour of Kloeckera apiculata Flocculent Strain in Coculture with Saccharomyces cerevisiae

The behaviour of the flocculent Kloeckera apiculata strain in coculture with the nonflocculent Saccharomyces cerevisiae strain, both yeasts isolated from wine, has been analyzed. Pure culture of Kloeckera apiculata (apiculate yeast) exhibits 75 % flocculation in the yeast extract/peptone/glucose (containing 20 g/L of glucose, YPG20) medium after 24-hour incubation at 28 °C. This yeast expresses...
