“…31 The output of HFC is about 1500 tons in china each year, and about 1000 tons of HFC are discarded aer use. Therefore, discarded HFC is an abundant agricultural waste, with some Chrysanthemum material recycled and used for biodiesel 32 and microbial fuel cells. 33 Most used Chrysanthemum material is discarded or burned, which may cause environmental pollution and is a waste of biological resources.…”

“…Raw glycerin, still called industrial or crude glycerin, is an important by-product of the biodiesel industry (Caldeira et al, 2016). Due to commercial restrictions of the market or the purification processes, often the raw glycerin is discarded as solid residue (Oliveira et al, 2016). When this occurs, it is usually incinerated and co-processed in cement kilns, which increase the overall biodiesel production cost.…”

This study aims to assess a new approach for concomitant valorization of two industrial wastes -raw glycerin and spent brewer's yeast -for the bioproduction of valuable carotenoids. Microbial pigments have numerous applications in the food and cosmetic industries. First, four cultures of yeasts were screened using pure glycerol and either (NH 4 ) 2 SO 4 or urea as carbon and nitrogen sources, respectively. The ability of the best performing culture to accumulate carotenoids was investigated in a medium in which only wastes were supplemented as carbon and nitrogen sources. All the fermentations were carried out in 500 mL-Erlenmeyer flasks containing 150 mL of the medium. Microbial culture was incubated at 30 °C and 150 rpm for 120 h. Particularly, R. marina was the strain with the biggest potential to produce total carotenoids (up to 420 μg g -1 ). The four major carotenoid pigments identified by LCAPCI-MS were β-carotene, γ-carotene, torulene, and torularhodin. All fermentation assays and all the determinations were performed in triplicate. Results show that the bioprocess proposed in this work is technically and environmentally feasible, and sustainable. The simultaneous use of raw glycerin and spent brewer's yeast for the production of carotenoids by R. marina is reported for the first time.
