The purpose of present study is to investigate the efficiency of different kinds of Turkish commercial bleaching earth materials for changes in different colour pigment concentrations in neutralized sunfl ower oils. The bleaching experiments were performed in a pilot system under at stable vacuum (50 mmHg) and temperature (100ºC) for 30 min. By examining the changes in chlorophyll, β-carotene and...
Germination potential, i.e. vigour manifested at sensu stricto germination, was studied in 22 rice varieties to distinguish between the genetic control for low vigour (lv) at fresh harvest and lv after ageing of seeds. For identifying seed vigour-associated DNA marker(s), correlative studies between (1) physiological parameters viz. germination of (a) unaged seeds under optimum and cold stressed condition,...
The mitochondrial DNA (mtDNA) polymerase was isolated from a protease-deficient yeast strain (PY2), and purified about 3000 fold by a column chromatography on phosphocellulose, heparin-agarose, and single-stranded DNA cellulose. The purified polymerase was characterized with respect to optimal nucleotide concentration, template-primer specificity and sensitivity to some inhibitors. These results were...
