1. Unfortunately, amoxicillin is not resistant to penicillinase so it is not effective against penicillinase-producing bacteria.

2. It is found that tie conditions for penicillinase membrane are: bovine serum albumin concentration 40%, glutaraldehyde concentration 1% and total enzyme activity 207.3U.

3. Church recalls seeing plasmid and gene sequences for the first time—penicillinase and insulin, the lac repressor and interferon.

4. This test apply for the penicillinase antibiotic and none-abided penicillinase antibiotic.

5. Orbenin is stable to staphylococcal penicillinase , and highly effective against resistant staphylococci.

6. UV spectrophotometric method to estimate the kinetic parameters of penicillinase on penicillin substrates was established.

7. The achievements in the fabrication and characterization of ruthenium oxide, and enzymatically modified electrode with penicillinase are described in detail.
