Fig. 5From: Mentholation affects the cigarette microbiota by selecting for bacteria resistant to harsh environmental conditions and selecting against potential bacterial pathogensOverview of relative abundances of OTUs that were statistically significantly different (p < 0.05) between mentholated Camel Crush (CCM) and non-mentholated Camel Crush (CC). OTUs are colored by Phylum and differentiated by Gram negative (a) and Gram positive (b) classification. A positive log2-fold change value denotes an OTU that is significantly higher in mentholated Camel Crush, while a negative log2-fold change indicates an OTU that is significantly higher in non-mentholated Camel Crush. The dotted line and arrows highlight the conversion in log2-fold change from negative to positive valuesBack to article page
