Abstract
A material with a scaffold comprising a series of at least partially spaced fibers and gas vesicles locates between fibers. The gas vesicles comprise external anchoring modules that are effective to anchor the gas vesicles to the fibers.
Claims4
A material comprising:
- a scaffold comprising a series of at least partially spaced bacterial-derived cellulose fibers produced by genetically modified G. xylinus bacteria with an upregulated dgc gene;
- and
- bacterial-derived gas vesicles produced by a-genetically modified B. subtilis bacteria and comprising GvpA and GvpC proteins, and located between fibers, wherein the gas vesicles comprise integral external anchoring modules that comprise cellulose binding modules that comprise CBM48, wherein the external anchoring modules are effective to link the gas vesicles to the bacterial cellulose fibers:
- wherein at least some of the gas vesicles have lengths from 0.1 to 2 microns.
