Introduction Ferroelectric material is physically tied to the material lattice due to the internal electric dipoles.
An emerging ferroelectric material today is Barium strontium titanate (BaxSr1-xTiO3) [2].
The BaxSr1-xTiO3 solution was prepared with barium acetate, strontium acetate and titanium (IV) isopropoxide used as starting materials using the sol-gel method.

This study focused on a series of probiotic bacteria such as Bacillus sp, Lactobacillus and yeast to find the most effective combinations. 2 Materials and methods 2.1 Microbes and incubation media Pathogenic E. coli, B. subtilis, L. casei and H. anomala were purchased from Institute of Microbiology, Chinese Academy of Sciences, Beijing, China.
The reason may be that B. subtilis can secrete some active materials such as bacteriocins and gramicidin to inhibit pathogenic bacterium prolification so as to reduce endogenous infections[8]. 4.2 Effects of the combined probiotics on inhibiting E. coli prolification Generally, there is a joint action among the probiotic microorganisms.
The reasons of Lactobacillus for inhibiting E. coli growth are that Lactobacillus can produce hydrogen dioxide, acidic materials (acetic acid, propionic acid and lactic acid, etc.) and bacterins, which have the ability to inhibit pathogenic bacterium growth[9].
It was reported that the low-pH environment could promote the materials of inhibiting microbes to show their inhibiting ability, which would be decreased with pH value increasing and lost at pH 6.0[13].
