Figure 3From: Raman microspectroscopy for species identification and mapping within bacterial biofilmsSpecies predictions. Species prediction results for 5 two-species mixed biofilms. A normal approximation to the binomial distribution has been used to determine the standard error in the mean. Biofilms with proportions of S. mutans statistically significantly different from results seen in pure S. sanguinis biofilms are marked by ‘*’.Back to article page
