Herbal extraction residues(HERs)cause serious environmental pollution and resource *** this study,a novel green route was designed for the comprehensive reutilization of all components in HERs,taking Magnolia officinalis residues(MOR)as an *** reluctant structure of MOR was first destroyed by alkali pretreatment to release the functional ingredients(magnolol and honokiol)originally remaining in MOR and to make MOR more accessible for hydrolysis.A metal–organic frame material MIL-101(Cr)with a maximum absorption capacity of 255.64 mg g^(-1)was synthesized to absorb the released honokiol and magnolol from the pretreated MOR solutions,and 40 g L^(-1)reducing sugars were obtained with 81.8%enzymatic hydrolysis rate at 10%MOR solid ***,382 mg L-1β-amyrin was produced from MOR hydrolysates by an engineered yeast *** total,1 kg honokiol,8 kg magnolol,and 7.64 kg β-amyrin could produce from 1 ton MOR by this cleaner process with a total economic output of 170,700 RMB.

Fox is an important economic fur animal with a very promising prospect. The fox mitochondrial COl gene-specific primers and probes were used to opti- mize and develop a real time fluorescence PCR system for rapid detection of fox-derived components. The results showed that the real time fluorescence PCR gave a very high sensitivity, with the detection limit as low as 12 fg DNA, and it did not present any cross reaction with other common species like pig, cow, sheep, dog, soybean and maize. It could be concluded that this method can be used as an effective method for detecting the fox-derived components in food and feedstuff, and can also be applied for distinguishing the fox fur from adulterants.

利用电子万能实验机和Hopkinson压杆实验装置对高速动车组使用的铝合金材料分别进行了准静态和不同应变率下的动态压缩实验,得到了相应的应力-应变曲线.实验结果表明,在不同应变率下,整个应力-应变曲线无明显的屈服现象,也无明显的屈服极限;该铝合金材料的屈服极限、瞬时流动应力均随着应变率的增大而增大,但在应变率较低时,两者增大的幅度并不显著,在应变率较高时,两者才随着应变率的增大而急剧增大;在动态加载条件下,该铝合金材料的变形表现出非线性特征.
