Hi Todd,
Another benefit of the natto food I am eating is the elimination of mercury in my body (and hopefully the ventricals!) .The bacillus natto (commonly called bacillus subtilis see below) oxidises the mercury

The fate and impact of elemental mercury in closed bacterial cultures were examined. The quantity of elemental mercury oxidized by bacteria ranged from small amounts for Pseudomonas aeruginosa, P. fluorescens, Escherichia coli, and Citrobacter to essentially ALL of the ADDED elemental MERCURY for Bacillus subtilis and B. megaterium.
