Illinois-UC Berkeley discovery turns seaweed into biofuel in half the time

ls and gives us a better product," he added.

Is seaweed a viable biofuel? Jin and his colleagues are using a red variety (Gelidium amansii) that is abundant on the coastlines of Southeast Asia. In island or peninsular nations that don't have room to grow other biofuel crops, using seaweed as a source of biofuels just makes good sense, he noted.

But biofuels made from marine biomass also have some advantages over fuels made from other biomass crops, he said.

"Producers of terrestrial biofuels have had difficulty breaking down recalcitrant fibers and extracting fermentable sugars. The harsh pretreatment processes used to release the sugars also result in toxic byproducts, inhibiting subsequent microbial fermentation," he said.

Jin cited two other reasons for use of seaweed biofuels. Production yields of marine plant biomass per unit area are much higher than those of terrestrial biomass. And rate of carbon dioxide fixation is much higher in marine biomass, making it an appealing option for sequestration and recycling of carbon dioxide.
