Optimization of medium constituents for the production of citric acid from byproduct glycerol using Doehlert experimental design

Improved Utilization of Crude Glycerol By-Product from Biodiesel Production

“…Lewinson (2007) reported 21.6 g/L of citric acid production in batch fermentation of glycerol with 54% yield using Yarrowia lipolytica NRRL YB-423. Imandi et al (2007) achieved 77.4 g/L of citric acid from crude glycerol using statistically optimized culture medium for Yarrowia lipolytica NCIM 3589. Rywińska et al (2010) studied the efficiency of crude glycerol fermentation toward citric acid in fed-batch system using two acetate negative-mutants of Yarrowia lipolytica..…”

Monascus pigment production in bioreactor using a co-product of biodiesel as substrate

“…There is a wide range of biotechnology products with high added value such as 1,3 propanediol and biosurfactants (AMARAL et al, 2009), citric acid (IMANDI et al, 2007) and ethanol (JARVIS; MOORE; THIELE, 1997), which can be produced using glycerin. The high amount of glycerin generated from biodiesel production, in Brazil and the world, means an abundant and cheap source of renewable raw materials in the coming years (MOTA; SILVA; GONÇALVES, 2009).…”

Valorization of agroindustrial solid residues and residues from biofuel production chains by thermochemical conversion: a review, citing Brazil as a case study

“…The production of a variety of products derived from glycerol through different routes can be found in the literature (Chi et al, 2007;Garcia et al, 1995;Imandi et al, 2007;Karinen and Krause, 2006;Meesters et al, 1996;Narayan et al, 2005;Papanikolaou and Aggelis, 2002;Zheng et al, 2006). However, with fluctuating and increasing oil prices and limited energy resources, crude glycerol is being considered as a fuel source.…”
