New research focuses on use of cactus pear in biofuel production

In Nevada, the University of Nevada reported that a research team led by University of Nevada, Reno researchers has identified several varieties of cactus pear that are particularly well-suited to producing biomass for fuels production.

The new findings build on earlier research led by John Cushman, a professor in the University’s Department of Biochemistry & Molecular Biology in the College of Agriculture, Biotechnology & Natural Resources. The earlier work identified the cactus pear as a climate-resilient, water-efficient and highly productive source of biomass for fuels production.

The variety that consistently produced the most biomass in the new test is a hybrid that’s a cross between a species of wild prickly pear native to Texas and a spineless variety developed by Peter Felker at Texas A&M University for use by commercial growers.

The research affirmed earlier findings that cactus pear is highly water-efficient, requiring much less water to produce the same amount of biomass produced by thirstier crops.

“This is a critical factor, as we know that the western United States has limited water supplies that are only becoming more limited with the current global climate crisis,” Cushman said. “So, we should be exploring more water-use efficient crops for our food, feed and bioenergy needs.”
