Fig. 4From: Mentholation affects the cigarette microbiota by selecting for bacteria resistant to harsh environmental conditions and selecting against potential bacterial pathogensOverview of relative abundances of bacterial OTUs that were statistically significantly different (p < 0.05) between custom-mentholated Camel Kings (CKM) and non-mentholated Camel Kings (CK). 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 custom-mentholated Camel Kings, while a negative log2-fold change indicates an OTU that is significantly higher in non-mentholated Camel Kings. The dotted line and arrows highlight the conversion in log2-fold change from negative to positive valuesBack to article page
