| titleOfInvention | Catalase-inactivating compounds and the use thereof |
| abstract | The invention relates to the sulfonyl esters of the general formula R 1 —COO—SO 1 -Z-R 2 , wherein Z, R 1 and R 2 are defined as in claim 1. The invention further relates to the use of one of the inventive compounds for modifying the kinetics of the enzymatic effect of catalase. A method for measuring a concentration in living and/or active microorganisms in a liquid sample ( 3 ) by means of the development of oxygen from hydrogen peroxide is also based on the abovementioned modification. An inventive compound is admixed in a container ( 1 ) to the sample said compound inactivates the enzymatic effect of endogenous catalase without substanially inactivating the enzymatic effect of the intracellular catalase of microoganisms. Hydrogen peroxide is added and immediately afterwards the pressure present in the sample container is briefly equalized with the atmosphere, the container is closed in a gas-tight manner ( 2 ) during a predetermined reaction time and the pressure in the container is measured ( 9,10,11 ). The pressure measured and the data regarding the microorganisms and the sample dilution are used to calculate ( 22 ) the concentration of living and/or active microorganism in the sample and the concentration is optionally displayed ( 24 ). The invention further relates to a device for carrying out the inventive method. |
