FILTERS COMPRISING MICROBIALLY-PRODUCED CELLULOSE

摘要

A fluid filter formed of microbially-produced cellulose, preferably formed into a web of cellulose fibers in artificial culture of the microbes, then removed from the culture and shaped into a filter. The shaping may include a compression step and may also include an embossing step. Methods of culturing and forming the filter are also disclosed.

1. A fluid filter, comprising:
a web of interlinked cellulose fibers, secreted by cellulose-secreting microorganisms, wherein the cellulose-secreting microorganisms are grown in artificial culture to form said web, wherein said web has been shaped into a fluid filter subsequent to said secretion, wherein the cellulose-secreting microorganisms comprises fungi, algae or bacteria, and wherein the cellulose-secreting microorganisms are genetically modified.
