Composition of the bacterial and archaeal populations classified at Family level and if possible on Genus level of sludge during growth on lactate + isoprene (a) and lactate only control (b) at time points 0, 156, and 204 days. Samples were inoculated with wastewater from St. Marys treatment plant. Other category is the sum of all classifications with <2% abundance. Classifications in the legend are clustered according to their phylum (from top to bottom); Actinobacteria, WWE1, Bacteroidetes, Proteobacteria, Spirochaetes, Firmicutes, Planctomycetes, Euryarchaeota. Depleted amounts of isoprene in each replicate are shown at the top. Only three out of four replicates were analyzed by Illumina sequencing
