Rhodococcus sp. YHY01 was studied to utilize various lignin derived aromatic compounds. It was able to utilize p-coumaric acid, cresol, and 2,6 dimethoxyphenol and resulted in biomass production i.e. 0.38 g dcw/L, 0.25 g dcw/L and 0.1 g dcw/L, and lipid accumulation i.e. 49%, 40%, 30%, respectively. The half maximal inhibitory concentration (IC) value for p-coumaric acid (13.4 mM), cresol (7.9 mM), and 2,6 dimethoxyphenol (3.4 mM) was analyzed. Dimethyl sulfoxide (DMSO) solubilized barley straw lignin fraction was used as a carbon source for Rhodococcus sp. YHY01 and resulted in 0.130 g dcw/L with 39% w/w lipid accumulation. Major fatty acids were palmitic acid (C16:0) 51.87%, palmitoleic acid (C16:l) 14.90%, and oleic acid (C18:1) 13.76%, respectively. Properties of biodiesel produced from barley straw lignin were as iodine value (IV) 27.25, cetane number (CN) 65.57, cold filter plugging point (CFPP) 14.36, viscosity (υ) 3.81, and density (ρ) 0.86.
研究了 Rhodococcus sp. YHY01 利用各种木质素衍生的芳香族化合物。它能够利用对香豆酸、甲酚和 2,6-二甲氧基苯酚，并分别导致生物量生产 0.38 g dcw/L、0.25 g dcw/L 和 0.1 g dcw/L，以及脂质积累 49%、40%和 30%。对半最大抑制浓度 (IC) 值对香豆酸 (13.4 mM)、甲酚 (7.9 mM) 和 2,6-二甲氧基苯酚 (3.4 mM) 进行了分析。二甲亚砜 (DMSO) 溶解的大麦秸秆木质素级分被用作 Rhodococcus sp. YHY01 的碳源，导致 0.130 g dcw/L 的生物量和 39% w/w 的脂质积累。主要脂肪酸分别为棕榈酸 (C16:0) 51.87%、棕榈油酸 (C16:l) 14.90%和油酸 (C18:1) 13.76%。从大麦秸秆木质素生产的生物柴油的特性为碘值 (IV) 27.25、十六烷值 (CN) 65.57、冷滤堵塞点 (CFPP) 14.36、粘度 (υ) 3.81 和密度 (ρ) 0.86。
