Reports indicate that this stimulus can occur due to hormesis, a phenomenon whereby bacteria secrete fungistatic substances that, if released in small quantities, can stimulate the genes of other microorganisms and initiate their growth (Mlot, 2009).
These examples may all be related to wide range of materials that stimulate positive effects at low concentrations but cause toxicity and inhibition at higher doses (hormesis effect) (Jaiswal et al.
