title: Pilot scale biodiesel production from microbial oil of Rhodosporidium toruloides DEBB 5533 using sugarcane juice: Performance in diesel engine and preliminary economic study.
abstract: A successful pilot-scale process for biodiesel production from microbial oil (Biooil) produced by Rhodosporidium toruloides DEBB 5533 is presented. Using fed-batch strategy (1000L working volume), a lipid productivity of 0.44g/L.h was obtained using a low-cost medium composed by sugarcane juice and urea. The microbial oil was used for biodiesel production and its performance was evaluated in diesel engine tests, showing very good performance, especially for the blend B20 SCO, when operating at 2500rpm with lower pollutant emissions (CO2- 220% less; CO - 7-fold less; NOX50% less and no detectable HC emissions (<0.11ppm)) when compared with the blends of standard biofuel from soybean oil. A preliminary analysis showed that microbial biodiesel is economically competitive (US$ 0.76/L) when compared to the vegetable biodiesel (US$ 0.81/L). Besides, the yield of biodiesel from microbial oil is higher (4172L/ha of cultivated sugarcane) that represents 6.3-fold the yield of standard biodiesel (661L/ha of cultivated soybean).
