Primary brewery wastewater as feedstock for the yeast Rhodosporidium toruloides and the microalga Tetradesmus obliquus mixed cultures with lipid production

Rhodosporidium toruloides and Tetradesmus obliquus pure mixed cultures were grown on primary brewery wastewater (PBWW), with without supplementation of sugarcane molasses (SCM) urea. R. developed in was not able to grow PBWW, or supplementation, but grew the microalga T. all media. In contrast, develop. Higher biomass productivity (149.3 mg L−1 h−1) obtained for culture using PBWW supplemented 10 g SCM 2 Therefore, a strategy stimulate lipid production by higher concentrations (20, 40 100 L-1 SCM) developed. The maximum content (26.3 % (w/w DCW)) plus urea, at t = 121 h. This work demonstrated feasibility urea as medium produce microbial lipids.
