AHLs are compounds whose synthesis is related to the entrance of bacteria into idiophase, increased production of secondary metabolites and virulence factors, sporulation, and biofilm formation.
A proposed role for diffusible signal factors in the biofilm formation and morphological transformation of Helicobacter pylori
The biosynthesis of these substances is influenced by physiological and environmental signals (3) and is mainly produced during idiophase. The secondary metabolites from Streptomycetes show several biological activities and can be broadly classified into four classes: (a) Antagonist agents, including antibacterials, antifungals, antiprotozoans as well as antivirals (b) Pharmacological agents, including antitumorals, immunomodulators, neurological agents and enzyme inhibitors (c) Agrobiologicals including insecticides, pesticides and herbicides and (d) Compounds with regulatory activities such as growth factors, siderophores or morphogenic agents.
