Researchers improve microbial oil production through optimized nitrogen combinations
In India, researchers have found that combining organic and inorganic nitrogen sources can improve lipid production in two oleaginous yeast strains, Rhodotorula kratochvilovae and Rhodotorula paludigena. The study showed that the optimal nutrient combinations differed between strains. In R. kratochvilovae, ammonium sulfate combined with yeast extract produced the highest lipid yield, at 1.219 grams per liter. In R. paludigena, the strongest result came from combining ammonium sulfate with urea, yielding 0.909 grams per liter. The findings could help optimize microbial oils as potential feedstocks for biodiesel and other bio-based products, although the experiments were conducted at laboratory flask scale.
