The selection of yeast strains adapted to fermentation stresses in their winegrowing area is a key factor produce quality wines. Twelve non-Saccharomyces native from Denomination Origin (D.O.) “Vinos de Madrid” (Spain), warm climate region, were tested under osmotic pressure, ethanol, and acidic pH stresses. In addition, mixed combinations between Saccharomyces cerevisiae strain practised. Phen...

Ribulose 1,5-diphosphate carboxylase was isolated from Euglena gracilis Klebs strain Z Pringsheim, Chlorella fusca var. vacuolata, and Chlamydobotrys stellata, and the subunits from each enzyme were separated and purified by gel filtration on Sephadex G-200 in the presence of sodium dodecyl sulfate. Rabbit antibody was elicited against purified Euglena ribulose 1,5-diphosphate carboxylase whole...

We investigated an old-growth oak-shortleaf pine (Pinus echinata) stand of high ecological integrity in east-central Oklahoma located west of the continuous native distribution of shortleaf pine. With the exception of an abundance of shortleaf pine, the basal area (17.2 m/ha), density (559.6 trees/ha), and species composition of this unmanaged stand is similar to other old hardwood forests in t...

The stopover behaviour of Black-throated Divers Gavia arctica and Red-throated stellata during autumn migration was observed in two sites Poland. Differences time-activity budget diving pattern were recorded from mid-October to mid-January 2004 2005. A total 1,516 minutes observation achieved. Birds spent their time (60.7%), followed by preening (14.8%), surface swimming (12.5%), other activiti...

Paullinia stellata is found in anthropogenic places and lowland forests, yet little information about their reproductive characteristics known. This study aimed to determine the physical properties of seeds aspects. Racemes, fruits, were measured weighed. The determined using three-dimensional data. A descriptive statistic was applied for racemes a small samples conducted properties. results sh...
