Microbial Lipid Production from Both Rice Straw Hydrolysates and Recycled Pretreated Glycerol<\/strong><\/p>\n

Recently, PhD student Mr. Song Tang<\/strong> supervised by Prof. Zhen FANG<\/strong> produced microbial lipid from both rice straw hydrolysates and recycled pretreated glycerol. First, lipid fermentation of glucose via Cryptococcus curvatus<\/em> was optimized by response surface methodology. Variables were selected by Plackett\u2013Burman design, and optimized by central composite design, achieving 4.9 g\/L total lipid and 0.16 g\/g lipid yield, and increased further as glucose increased from 30 to 50 g\/L. It was found that lipid content rapidly decreased from 44.5% to 6.4% as lignin (0.5 g\/L) was added, which would inhibit lipid accumulation for hydrolysate and recycled glycerol. Secondly, these fermentation conditions were further used for rice straw hydrolysates. After glycerol-FeCl3<\/span><\/sub> pretreatment (0.06 mol\/L FeCl3<\/span><\/sub>, 150 \u00b0C and 20 min), 72% lignin of rice straw was removed with glucose yield increased by 2.4 times to 74.3% at 20% substrate loading and 3 FPU\/g dry substrate. Its hydrolysates were separated for lipid fermentation, producing high total lipid (8.8 g\/L) and lipid yield (0.17 g\/g). Finally, recycled glycerol reached the maximum total lipid of 7.2 g\/L and high lipid yield of 0.16 g\/g. Based on the calculation, 2.9 g total lipid would be produced from 1 g rice straw and the recycled glycerol, with a similar composition to soybean oil.<\/p>\n
