Crabtree Effect on Rhodosporidium toruloides Using Wood Hydrolysate as a Culture Media

The interest in microorganisms to produce microbial lipids at large-scale processes has increased during the last decades. Rhodosporidium toruloides-1588 could be an efficient option for its ability simultaneously utilize five- and six-carbon sugars. Nevertheless, one of most important characteristics that any strain needs considered or used industrial scale is capacity grow substrates with high sugar concentrations. In this study, effect concentrations ammonium sulfate were tested on R. accumulate using undetoxified wood hydrolysates. Batch fermentations showed a catabolic repression growth 120 g/L. maximum lipid accumulation was 8.2 g/L palmitic, stearic, oleic, linoleic, lignoceric acids as predominant fatty produced lipids. Furthermore, able up 80% total xylose content. Additionally, study first report growth, utilization, by toruloides-1588.
