FollowLondon, UK — The use of kelp (Laminaria digitata) could provide an important alternative to terrestrial grown biofuels, but the suitability of its chemical composition varies on a seasonal basis. Harvesting the kelp in July when carbohydrate levels are at their highest would ensure optimal sugar release for biofuel production.
“The storage carbohydrate and soluble sugars get converted into ethanol in the fermentation process, so we need as much as possible,” explained Dr. Jessica Adams, a lead researcher at Aberystwyth University. “Metals can inhibit the yeast too so we also want these to be as low as possible.”
