Growth and surface properties of new thermoacidophilic Archaea strain Acidianus manzaensis YN-25 grown on different substrates

新 thermoacidophilic Archaea 的生长和表面性质拉紧在 Tengchong 从一个酸温泉孤立的 Acidianus manzaensis YN-25，云南省，中国被调查在包括可溶的底层的不同底层上有教养铁的硫酸盐和 nonsoluble 固体底层 S0，黄铁矿和黄铜矿。在每底层的细胞的生长特征在细胞数字与变化被描绘， pH ，啊，并且Fe2+或 SO42 的集中?，或比率[Fe2+]到[Fe3+]，并且表面性质以希腊语的第六个字母潜力被描绘并且分析， hydrophobicity ，并且出现细胞的英尺红外系列。结果证明在稳固的底层上种的房间有等电位的点的更高的价值。他们是更恐水病的并且比铁的硫酸盐表示更多的表面蛋白质成年房间。

The growth and surface properties of new thermoacidophilic Archaea strain Acidianus manzaensis YN-25 isolated from an acid hot spring in Tengchong, Yunnan Province, China were investigated cultured on different substrates including soluble substrate ferrous sulfate and nonsoluble solid substrates S^0, pyrite and chalcopyrite. The growth characteristics of the cells in each substrate were characterized with the changes in cell number, pH, Eh, and concentrations of Fe^2＋ or SO4^2- , or ratios of [Fe^2＋] to [Fe^3＋], and the surface properties were characterized and analyzed in terms of Zeta-potential, hydrophobicity, and surface FT-IR spectra of the cells. The results show that the cells grown on solid substrates have higher value of isoelectric points. They are more hydrophobic and express more surface proteins than ferrous sulfate grown cells.
