Figure 3

TEM image showing the formation of extracellular and intracellular Te0 NPs produced by the anaerobic granules using TeVI as the initial source of Te with H2 as exogenous source of electrons, in the presence or absence of lawsone. Panels A and B, Te0 NPs formed extracellularly and intracellularly when the bioassays were amended with H2 as electron donor with no RM, respectively. Panels C and D, Te0 NPs formed when the bioassays were amended with lawsone as RM.
