Stanford, CA — Photosynthesis provides fixed carbon and energy for nearly all life on Earth, yet many aspects of this fascinating process remain mysterious. For example, little is known about how it is regulated in response to changes in light intensity. More fundamentally, we do not know the full list of the parts of the molecular machines that perform photosynthesis in any organism.

A type of single-cell green algae called Chlamydomonas reinhardtii is a leading subject for photosynthesis research. Despite its importance in the research world, few tools are available for characterizing the functions of its genes. (more…)

Boosting Galactan Sugars Could Boost Biofuel Production

Collaboration at JBEI Identifies the First Enzyme Linked to Galactan Synthesis

Galactan is a polymer of galactose, a six-carbon sugar that can be readily fermented by yeast into ethanol and is a target of interest for researchers in advanced biofuels produced from cellulosic biomass. Now an international collaboration led by scientists at the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI) has identified the first enzyme capable of substantially boosting the amount of galactan in plant cell walls.

Unlike ethanol, advanced biofuels synthesized from the sugars in plant cells walls could replace gasoline, diesel and jet fuels on a gallon-for-gallon basis and be dropped into today’s engines and infrastructures with no modifications required. Also, adanced biofuels have the potential to be carbon-neutral, meaning they could be burned without adding excess carbon to the atmosphere. Among the key challenges to making advanced biofuels cost competitive is finding ways to maximize the amount of plant cell wall sugars that can be fermented into fuels. (more…)

New Mouthwash Targeting Harmful Bacteria May Render Tooth Decay A Thing of The Past

A new mouthwash developed by a microbiologist at the UCLA School of Dentistry is highly successful in targeting the harmful Streptococcus mutans bacteria that is the principal cause tooth decay and cavities.

In a recent clinical study, 12 subjects who rinsed just one time with the experimental mouthwash experienced a nearly complete elimination of the S. mutans bacteria over the entire four-day testing period. The findings from the small-scale study are published in the current edition of the international dental journal Caries Research. (more…)
