The isolate grew well in R2 liquid medium and could pass through 0.22 μm and 0.45 μm filtrate membranes. The colony was grain-like in solid medium. Through electron microscopy, the isolate YY0801 exhibited helicity during their exponential growth phase. The isolate YY0801 was able to ferment glucose and D-fructose and to catabolize arginine, but did not to hydrolyse urea. The isolate was resistant to ampicillin (2000 U/mL).

With increasing monomer concentration inside the disperse phase, the monodispersity of emulsions became slightly worse and the mean diameter of emulsions gradually became smaller. Monodisperse monomer-containing emulsions were obtained when the SPG membrane pore size was larger than 1.0 μm; however, when the SPG membrane pore size was smaller than 1.0 μm, no monodisperse emulsions were obtained because of the formation and chokage of p-phthalic acid crystals in the pores of the SPG membrane.

当SPG膜孔径大于1.0 μm左右时，可得到单分散的含TDC单体乳液；而当孔径小于1.0 μm左右时，水分子更容易扩散并溶解到油水界面甚至油相内部与TDC生成对苯二甲酸，TPA积累到一定程度在油水界面上析出将膜孔堵塞，从而无法制得单分散乳液。

The results showed that the D50 of Astragalus membranaceus and Epimedium brevicornum ultra-fine powder were 6.82μm and 8.40μm separately. The broken cellular walls of two ultra-fine herbal powder were bigger than those of the commonly cribble, and intact cells were not visible under SEM, and it improved the mixed uniformity. On the contrary, organization blocks of the commonly cribble were clearly discernible, also the shape and granularity were irregular, and the organization cells were still complete. The bulk density and liquidity of Astragalus membranaceus and Epimedium brevicornum increased significantly after ultra-fine Smashing. The component icariin extraction content of the ultra-fine powder was enhanced by 18.31% compared with the cribble by the chromatograph analysis of icariin. At the same time, Astragalus membranaceus polysaccharide and Epimedium brevicornum polysaccharide content of the ultra-fine powder were enhanced by 117.13% and 315.15% compared with the cribble.
