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

•R. toruloides and T. obliquus pure and mixed cultures were grown on PBWW.•R. toruloides did not grow in pure cultures but grew in mixed cultures.•T. obliquus pure cultures grew on PBWW attaining higher DCW than in mixed cultures.•PBWW supplemented with sugarcane molasses and urea was used to grow mixed cultures.•A maximum lipid content of 26.3 % (w/w DCW) when PBWW + urea+100 g/l SCM was used.
