A new strain of yellow-green algae, heterococcus sp. DN1, which may prove to be an efficient source for biodiesel, has been discovered in the snow fields of the Rocky Mountains. Research examining this new alga, published in Biotechnology Progress, reveals that H. sp. DN1 was found to grow at temperatures approaching freezing and to accumulate large intracellular stores of lipids.
Algae that can grow in extreme conditions and accumulate lipids are of great interest to industry. The team found that as H. sp. DN1 produces the highest quantity of lipids when grown undisturbed with high light in low temperatures, it is a potential source of lipids for human nutrition; and it has an ideal lipid profile for biofuel production when stressed.
“We have isolated and characterized a new cold-tolerant lipid-producing strain of algae from the Rocky Mountains in Colorado, U.S.,” said David R. Nelson with the Department of Plant Biology at the University of Minnesota in St. Paul. “This may have implications for the commercial production of algal lipids at northern latitudes where the culture of other algal species is limited or impossible.”

Repsol and Bunge on April 25 announced plans to incorporate the use of camelina and safflower feedstocks in the production of renewable fuels, including renewable diesel and sustainable aviation fuel (SAF).
U.S. operable biofuel capacity in February was unchanged from the previous month, according to data released by the U.S. EIA on April 30. Feedstock consumption for February was down when compared to both January 2025 and February 2024.
CARB on April 4 released a third set of proposed changes to the state’s LCFS. More than 80 public comments were filed ahead of an April 21 deadline, including those filed by representatives of the ethanol, biobased diesel and biogas industries.
The USDA on April 14 announced the cancellation of its Partnerships for Climate-Smart Commodities program. Select projects that meet certain requirements may continue under a new Advancing Markets for Producers initiative.
The USDA reduced its outlook for 2024-’25 soybean oil use in biofuel production in its latest World Agricultural Supply and Demand Estimates report, released April 10. The outlook for soybean oil pricing was revised up.
