Researchers have discovered that the human oral microbe Streptococcus mutans has a significant capacity for producing natural products through biosynthesis. However, other studies appear to be focused on different microorganisms, such as Lactobacillus and the fungus Diaporthe kyushuensis, and their respective abilities to produce bacteriocins and secondary metabolites. The connection between these findings is unclear, as the research seems to be exploring various aspects of microbial biosynthesis.
