Description

Application

• Bacteriocin Against MRSA: This research highlights the application of ammonium sulfate in the purification of novel bacteriocins from Lactiplantibacillus plantarum for combating methicillin-resistant Staphylococcus aureus, demonstrating its critical role in biomedical research and pharmaceutical applications (Ye et al., 2024).

Analysis Note

Appearance of solution (10 g/l; ethanol): passes test
Loss on drying (110 °C): ≤ 1.0 %
Suitability as indicator (for metal titration): passes test
Suitability for bromate determination in water and drinking water for Pharo- or NOVA-spectrophotometer: passes test
Application note: Method A or Method B

Method A:For the measurement the method 195, which is pre-calibrated in the Spectroquant Pharo-and NOVA-photometers can be
used. To increase the precision of the results a self-made blank according to the application is recommended generally.
Method B:For the measurement the pre-calibrated method 195 is not applicable. Instead of that, a self-made calibration according the
application is to perform.
