Weed stems ripe for biofuel

June 1, 2016 |

In Australia, a weedy plant found on the roadside in northern Australia has stems ripe for biofuel production. Scientists from the ARC Centre of Excellence in Plant Cell Walls at the University of Adelaide have discovered that a variety of sorghum growing wild in Australia, Arun, has the potential to yield over 10,000 litres of bioethanol per hectare per year.

In a study published in the journal PLOS ONE, the researchers assessed the stems of 12 varieties of sorghum for sugar content and ease of conversion to bioethanol. These included cultivated varieties and wild relatives, including Arun, which yielded significantly more bioethanol than other varieties.
