Simultaneous Determination of Nitroimidazoles and Quinolones in Honey by Modified QuEChERS and LC‐MS/MS Analysis

International Journal of Analytical Chemistry, Volume 2018, Issue 1, 2018., 2018
This study reports an analytical method for the determination of nitroimidazole and quinolones in honey using liquid chromatography‐tandem mass spectrometry (LC‐MS/MS). A modified QuEChERS methodology was used to extract the analytes and determine veterinary drugs in honey by LC‐MS/MS.

Lipopeptides as the Antifungal and Antibacterial Agents: Applications in Food Safety and Therapeutics

BioMed Research International, Volume 2015, Issue 1, 2015., 2015
A lot of crops are destroyed by the phytopathogens such as fungi, bacteria, and yeast leading to economic losses to the farmers. Members of the Bacillus genus are considered as the factories for the production of biologically active molecules that are potential inhibitors of growth of phytopathogens.
