Here’s blog post II on the biofuel research studies I received earlier this month. To read the first blog post, click here: Ion Chromatography Biofuel Research Studies (I).
This first study (available as a downloadable free PDF if you click the link above) uses one of our lower-end Ion chromatography systems (Thermo Scientific Dionex ICS-2000 system) for analysis ofnitrate, nitrite, and sulfate concentrations with one of our anion-exchange analytical columns (Thermo Scientific Dionex IonPac AS11 analytical column) and conductivity suppression.
Study: Analysis of Keystone Enzyme in Agar Hydrolysis Provides Insight into the Degradation (of a Polysaccharide from) Red Seaweeds
This study (link is to abstract; only the abstract is free) was conducted jointly by two universities in Canada: University of Victoria and Simon Fraser University on how polysaccharides from red seaweed could be released by bacterial action for biofuel production. I did a little research on red seaweeds and found a couple of articles that mentioned red seaweed being well suited to biofuel production as it grows faster than other types of seaweed. Also, the advantage of using seaweed for biofuels is two-fold: one, they do not use up valuable fresh water supplies and two, they do not use valuable land which could be used for food production. (Isn’t the image of the seaweed absolutely beautiful?)
For the research described in the above article, the equipment used included our mid-level Ion Chromatography (IC) systems (Thermo Scientific Dionex ICS 3000 system) equipped with our IC electrochemical detector with a gold working electrode (link to post on this blog).

The focus of this study (above link is to abstract; only the abstract is free) was to “provide insight into grass xylan synthesis and how substitutions may be modified for increased saccrification for biofuel generation.” The rationale for the study was, again from the abstract, “Xylan is the second most abundant polysaccharide on Earth and represents an immense quantity of stored energy for biofuel production. Despite its importance, most of the enzymes that synthesize xylan have yet to be identified.”
The study used theHigh-Performance Anion-Exchange Chromatography with Pulsed Amperometric Detection (HPAE-PAD) technique on one of our mid-level Ion Chromatography (IC) systems (Thermo Scientific Dionex ICS 3000 system). The HPAE-PAD technique is commonly used to determine anionic analytes without derivatization and is used for the analysis of carbohydrates, including mono-, di-, tri-, oligo- and polysaccharides, sugar alcohols, and amino sugars.
This study was jointly conducted by the University of California at Davis,Joint BioEnergy Institute in California, University of California at Berkeley, Lawrence Berkeley National Laboratory in California, University of Copenhagen in Denmark, and Kyung Hee University in Korea.
