Engineering the production of α-bisabolene in R. toruloides. a Correlation between PGAPDH-BIS copy number and α-bisabolene titer at day 8 in SD medium containing 20 g/L glucose. b Production of α-bisabolene in SD medium containing 10 g/L glucose by three strains harboring the PGAPDH-BIS cassette at various copy numbers (shown as points of corresponding color in A) and strain GB2, built by insertion of 6 copies of PANT-BIS into strain BIS3. BIS, α-bisabolene synthase from Abies grandis; PGAPDH, R. toruloides glyceraldehyde 3-phosphate dehydrogenase promoter; PANT, R. toruloides adenine nucleotide translocase promoter
