Co-expression of thermophilic pectinases in a single host for cost-effective pectin bioconversion into D-galacturonic acid

investigating the integration of translation technologies into translation programs in iranian universities: basis for a syllabus design in translation technology

today, information technology and computers are indispensable tools of any profession and translation technologies have become an indispensable part of translator’s workstation. with the increasing demands for high productivity and speed as well as consistency and with the rise of new demands for translation and localization, it is necessary for translators to be familiar with market demands an...

The transcriptional activator GaaR of Aspergillus niger is required for release and utilization of d‐galacturonic acid from pectin

We identified the d-galacturonic acid (GA)-responsive transcriptional activator GaaR of the saprotrophic fungus, Aspergillus niger, which was found to be essential for growth on GA and polygalacturonic acid (PGA). Growth of the ΔgaaR strain was reduced on complex pectins. Genome-wide expression analysis showed that GaaR is required for the expression of genes necessary to release GA from PGA an...

Determination of Galacturonic Acid Content of Pectin Using a Microtiter Plate Assay

The amount of galacturonic acid residues in samples containing pectin is an important parameter in the quantitative and structural analysis of this complex polysaccharide. This paper describes a method to determine the content of galacturonic acids in samples containing pectin, using a glass microtiter plate and microtiter plate-reading equipment with standard interference filters. The assay is...
