A proprietary potent and stable alternative to chemical neutralizers such as pyruvate - for the utilization in environmental monitoring applications. Use of catalase as a supplement in media plates offers a more effective and reliable solution for safe and secure environmental monitoring of sterilization in clean rooms, isolators or production facilities by also removing remaining traces and spots of high concentration of H2O2. Currently, agar plates for monitoring disinfection or sterilization are supplemented with pyruvate, which is consumed during the neutralization of hydrogen peroxide. One of the main benefits of this catalase is its high stability in agar media at 50°C, which allows easy preparation of media and processing into plates. Due to the high stability no special storage conditions are needed and a shelf-life of > 6 months at 4-25°C can be guaranteed.
Key features are:

A catalase product which neutralizes hydrogen peroxide at much higher concentrations (>10 %) compared to pyruvate, which is only capable of completely neutralizing hydrogen peroxide at the lowest concentration tested (2 %). Catalase (EC 1.11.1.6) catalyzes the following reaction:2H2O2 → 2H2O + O21 unit of catalase will decompose 1.0 μmole of H2O2 per min at pH 7.0 and 25 °C.

Phospholipase D 040, concentrated (100 U/mg), spray-dried, recombinant, of prokaryotic origin, is an enzyme preparation designed for advanced biochemical applications.

VIM-15 (β-Lactamase) is an enzyme product, specifically a metallo-beta-lactamase, which is sourced from certain resistant bacterial strains. This enzyme functions by hydrolyzing the beta-lactam ring of antibiotics, rendering them ineffective. The primary mode of action involves the coordination of zinc ions at its active site, enabling the breakdown of a broad spectrum of beta-lactam antibiotics including penicillins, cephalosporins, and carbapenems. This enzymatic activity significantly contributes to antibiotic resistance, posing a challenge in the treatment of bacterial infections. Its prevalence is noted in healthcare settings, where multidrug-resistant organisms are a concern. VIM-15 is of particular interest in clinical microbiology research and antimicrobial resistance studies, where understanding its structure and function can aid in the development of new inhibitors, potentially restoring the efficacy of beta-lactam antibiotics against resistant strains. Its characterization and study are critical for developing strategies to combat antibiotic-resistant infections effectively.

Pancreatin is an enzyme preparation, which is derived from the porcine pancreas. This product contains a mixture of several digestive enzymes, including amylase, lipase, and protease.
