| Abstract: | A simple apparatus for measuring hardness of Gelrite and agar plates, that can be easily fabricated, is described. It gives reproducible results comparable with those obtained with expensive commercial equipment. It has been successfully used to improve enumeration ofThiobacillus ferrooxidans andT. thiooxidans on solid media plates. |
