Figure 4From: An improved genetic system for bioengineering buoyant gas vesicle nanoparticles from HaloarchaeaPhenotype of Halobacterium sp. NRC-1∆ ura 3∆ gvp C and derivative strains containing gvp C expression plasmids with fragments of varying lengths. Increasing opacity (from orange to pink color) indicates higher levels of GVNPs produced in cells. Cultures of the following strains are shown spotted on CM+ plates: A: Halobacterium sp. NRC-1Δura3ΔgvpC, B: Halobacterium sp. NRC-1Δura3ΔgvpC (pARK-C1), C: Halobacterium sp. NRC-1Δura3ΔgvpC (pARK-C2), D: Halobacterium sp. NRC-1Δura3ΔgvpC (pARK-C3), E: Halobacterium sp. NRC-1Δura3ΔgvpC (pARK-C4), and F: Halobacterium sp. NRC-1Δura3.Back to article page
