Description
Summary:Bacterial secondary metabolites are low molecular mass compounds, which are not essential for bacterial growth. These secondary metabolites are produced in the stationary phase of bacterial growth and the produced compounds could have a variety of biological functions. One of these functions are the antibiotic or antimicrobial function that is gaining interest in the microbial community recently. In this work Gram-negative bacterial strains were cultivated, and their produced secondary metabolites were extracted and tested in antimicrobial plate assays against Gram-positive and Gram-negative bacterial strains as well. The well-known antibiotic, pyrrolnitrin content of the extracts were also determined by HPLC-Quadrupole-Orbitrap MS.
