The ionomer membrane under the conditions of 20℃ and 0.05 MPa shows better permeaselectivities that the permeability coefficient of CO_2 and CO_2/ N_2 separation factor are 223 Barrer and 65.70, respectively, while CO_2 / CH_4 separation factor is only 14.70. An obvious increase in P_(CO_2) with decreasing pressure difference exhibits a characteristic of facilitated CO_2 transport, which is not disappear and almost unchange after two months. There is no this behavior for N_2 and CH_4. Hence, P_(CO_2) and α_(CO_2/N_2) and α_(CO_2/CH_4) can be enhanced simultaneously.

该离聚体膜显示出良好的CO_2渗透性能，在20℃和0.05MPa压差下，CO_2渗透系数P_(CO_2)和CO_2/N_2分离系数αCO_2/N_2分别高达223 Barrer和65.70.P_(CO_2)和αCO_2/N_2随CO_2压差的降低而明显增大，显示出促进输送特征，这一行为即使在膜放置2个月之后并不消失，渗透分离性能变化不大。N_2和CH_4无此性能，因此在气体压差较低时，P_(CO_2)和αCO_2/N_2、αCO_2/CH_4可同时提高。

Results We isolated 2 strains of Bdellovibrio sp.(5#-12 and 5#-sh06) from sea mud of Shenzhen bay. Both strains grew between 20℃ and 35℃, with 25℃ and 30℃ as optimal temperature for 5#-12 and 5#-sh06, respectively. They grew between pH 6.1 and 8.6, and the opti℃mal pH for both was 7.2. Lysis experiments on 58 strains of pathogens were conducted and the results showed that 5#-12 and 5#-sh06 lysed 46 and 48 strains, corresponding to 79.3% and 82.8% of lysis abilities. Taken both two Bdellovibrio strains together, they lysed 96.6%(56 strains) of tested pathogens and 100% of tested vibrios (39 strains).
