Fig. 2From: Isolation and characterisation of Methylocystis spp. for poly-3-hydroxybutyrate production using waste methane feedstocksConjugation efficiencies of BRCS1 and BRCS2 compared to established strain M. parvus OBBP (OBBP) with two differing plasmids. a Plasmid pMTL90882 harbouring the ColE1 replicon and b pMTL70401 harbouring the pBBR1 replicon. Statistically significant difference is indicated with an asterisk compared to the OBBP control and calculated by t-test as indicated in the text. All samples n = 2 with error-bars representing SEM.
