The subject of the present invention is to provide a β-lactam acylase protein having high activity, a gene coding for said β-lactam acylase protein, a recombinant vector having said gene, a transformant containing said recombinant vector, and a method of producing a β-lactam antibiotic such as amoxycillin using said β-lactam acylase. A β-lactam acylase gene of Stenotrophomonas maltophilia was cloned, the DNA base sequence and the amino acid sequence expected therefrom was determined, and a Stenotrophomonas β-lactam acylase gene was obtained. This gene was found to code for a protein with a molecular weight of about 70 kDa and having β-lactam acylase activity, and could efficiently produce amoxycillin without being inhibited by phenylacetic acid, etc. Furthermore, by modification of the amino acid sequence, a protein which can more efficiently produce amoxycillin could be obtained.

The even system electricity induction operation medium of this invention has 3 halogen atoms, especially fluorine atom into a/the molecule at least it is the even system electricity induction operation medium including one kind of liquid state organic compound at least. A even system electricity induction operation medium about-the electric conduction rate under the operation environment temperature are the electricity induction operation medium that, is in the range of 4×10−10˜5×10−6S/m and the surface tension of the even system electricity induction operation medium under the operation environment temperature are 22 dyn/cm following. This even system electricity induction operation medium is difficult combustion or noninflammable nature. This even system electricity induction operation medium is difficult combustion or noninflammable. The movement style of the medium is formed among the electrode when a un-uniform electric field is formed to this electricity induction operation medium and can use this movement style to the device such as ECF motor, pump, washing device. The electricity induction operation medium of this invention is noninflammable almost because a particular halogen atom, especially fluorine compound are contained and there is not the risk of ignition even if the spark etc. results among the electrode. Also, the movement style of the electricity induction operation medium can be formed effectively because the electric conduction rate and also surface tension are in a particular range.
