X-ray diffraction patterns of SFRs before and after NaOH-heat pretreatment. The pretreatment of SFRs was performed in 1% (w/v) NaOH solution with a solid-liquid ratio of 1:10 (w/v) at 80 °C for 60 min. Based on the above analysis, the main mechanism of NaOH-heat pretreatment was to effectively remove lignin and acetyl from hemicellulose. It was suggested that the delignification and deacetylation improved the accessibility of cellulose to enzymes and enzymatic hydrolysis (Zhu et al. 2008; Castro et al. 2017). This was due to the deacetylation of hemicellulose molecule by NaOH-heat pretreatment, and the acetyl group broke from the hemicellulose molecule chain to produce acetic acid (Castro et al. 2017). Lactic acid concentration (33.7 g/L) produced from SFRs with NaOH-heat pretreatment was twice as high as that of SFRs without pretreatment. Dried root of Sophora flavescens (Fabaceae), known in Chinese as Ku-Shen, is widely used in traditional Chinese Medicine as a “cooling” drug for the treatment of gastrointestinal hemorrhage, skin diseases, and pyretic stranguria. The related reagents were purchased from Sinopharm Chemical Reagent Co., Ltd. (Shanghai, China). The pretreatment of SFRs was performed in 1% (w/v) NaOH solution with a solid-liquid ratio of 1:10 (w/v) at 80 °C for 60 min. Sophora flavescens Aiton, Hort.

(2018).   The optimization and mechanism of the best pretreatment method was explored. The cellulose, hemicellulose, and Klason lignin content of the untreated and pretreated SFRs were determined according to the National Renewable Energy Laboratory Analytical Procedure (Sluiter et al. 2008). Accordingly, the SFRs samples were degraded by using 72% sulfuric acid at 30 °C for 1 h, then diluted to 4% sulfuric acid, and further degraded at 121 °C for 1 h. The content of cellulose and hemicellulose was quantified by the concentration of corresponding monomeric sugars, using an anhydro correction of 0.88 for pentose and a correction of 0.90 for hexose, respectively. Under the optimum NaOH-heat pretreatment conditions (1% (w/v) NaOH solution; 1:10 (w/v) solid-liquid ratio; 80 °C temperature; 60 min treatment time), 85.0% hydrolysis efficiency was obtained. Sophora prostrata ‘Little Baby’ is smaller than the species, but still displays the characteristic divaricating (zigzagging) growth and yellow blooms. 1789. 苦参 ku shen.

However, the market price of lactic acid is 9000 to 14000 RMB/t; thus, it is of great economic significance to explore SFRs to produce lactic acid by biological fermentation. In order to explore the effect of pretreatment on the lactic acid production, the same amount of SFRs with non-pretreatment and pretreatment were used to hydrolyze and ferment. This result indicated that the alkali solution could dissolve most of lignin in SFRs. Neben Matrin und seinem N‐Oxyd werden Methylcytisin, Anagyrin, Baptifolin und ein neues Alkaloid, ein Hydroxymatrin, aus den Wurzeln von Sophora flavescens isoliert.

Under the optimum conditions, 22.0 g/L reducing sugar was obtained from enzymatic hydrolysate of SFR, and the hydrolysis efficiency was 85.0%. Because the functional groups and chemical bonds of cellulose have specific frequencies in infrared spectroscopy, the changes of structure and composition of cellulose before and after pretreatment can be qualitatively and semi-quantitatively analyzed by infrared spectroscopy. However, polysaccharides as main components in the root remained unknown. E. 12(2), 147-151. The hydrolysis efficiency was calculated with Eq. “Overall evaluation of microwave-assisted alkali pretreatment for enhancement of biomethane production from brewers’ spent grain,” Energ. Although the solid recovery after NaOH-heat pretreatment was slightly lower than that of hydrothermal and H2SO4-heat pretreatment, the reducing sugar yield after enzymatic hydrolysis was the highest, reaching 34.7 to 34.8 g/(100 g dry residue).
