(28.) Dikeman T.L: Study of Acidogenie and Aciduric micro organisms in orthodontic and non-orthodontic patients.
mutans serotypes are both acidogenic and aciduric and are strongly stimulated by sucrose (Roberson, T., H.O.
Aciduric bacteria such as the mutans streptococci can carry out glycolysis at low pH values within the biofilm's matrix even though glycolytic enzymes are not acid tolerant, because the bacteria maintains pH across the cell membrane with the interior more alkaline than the exterior.
In addition to the positive clinical outcomes of IPT, the residual discoloured infected dentine has been found to harden [Marchi et al., 2006] and its population of aciduric bacteria to drop dramatically in a matter of months [Lula et al., 2009].

These cassettes can quickly monitor airborne yeast, mold and aciduric microorganisms in critical areas.
Key words: bacillus, aciduric, effervescence, spore-formers, lysine decarboxylase, cadaverine.
Streptococcusmutans being aciduric is the most cariogenic bacteria.
