Effects of inorganic nitrogen addition to okara-utilized medium on the oleaginous yeast Lipomyces starkeyi and assessment of metabolism involved in increased oil production.

ABSTRACT:

Background

Oleaginous microorganisms contain oil and fat at amounts greater than 20% of their biomass weight, with fatty acid and chemical compositions often similar to those of vegetable oil and animal fat. Oleaginous yeasts, including Lipomyces starkeyi, are particularly promising because of their high oil accumulation capacity, broad sugar utilization, and ability to use non-edible biomass, making them suitable for large-scale, cost-effective oil production. However, reducing production costs remains a major challenge, as media costs account for the majority of total microbial oil production costs. Okara, a byproduct of tofu and soy milk production, is a potential low-cost nitrogen source. Although previous study have reported the use of solid okara for oil production and its lo
