Effects of biomass hydrolysis by-products on oleaginous yeast Rhodosporidium toruloides

Lipid production by Lipomyces starkeyi cells in glucose solution without auxiliary nutrients

“…Cells were harvested by centrifugation, washed twice with distilled water and dried at 105 • C to a constant weight (Hu et al, 2009). Residual glucose was determined by the SBA-50B glucose analyzer (Shandong Academy of Sciences, Jinan, China) according to the manufacturer's instruction.…”

Fatty acid ethyl esters production in aqueous phase by the oleaginous yeast Rhodosporidium toruloides

“…Ethanol fermentation broth normally contains less than 20% ethanol, plus water and byproducts such as acetaldehyde, glycerol and acetic acid. It has been known that the oleaginous yeast Rhodosporidium toruloides is a robust lipid producer as it can accumulate lipid over 70% with a titer of over 100 g/L (Li et al, 2007), and utilize lignocellulosic hydrolysates with excellent tolerance towards inhibitory compounds (Hu et al, 2009). Lipids in this yeast can be recovered easily by enzyme-assisted extraction .…”

Microbial lipid production by Rhodosporidium toruloides under sulfate-limited conditions

“…R. toruloides Y4 was an excellent storage lipid producer because high cellular lipid content (Li et al, 2006) and high cell density (Li et al, 2007) could be easily achieved. It also showed excellent tolerance to lignocellulosederived inhibitors (Hu et al, 2009). In this paper, we investigated the lipid production profile of this strain in a defined media with various amounts of sulfate supplements.…”
