Claim 0:
1. A method for producing bacterially synthesized cellulose (BC) non-woven, the method comprising the steps of:
a) synthesizing BC by incubating a bacterial culture in a culture vessel, wherein the bacterial culture comprises a liquid culture medium and a BC-synthesizing bacteria,
b) adding fresh or recycled culture medium and/or removing consumed culture medium during the incubation as an optional step,
c) removing produced BC non-woven having an average thickness of at least 0.5 mm from the culture vessel,
wherein at least during step a) the gaseous atmosphere above the bacterial culture is controlled to be at a temperature that is at most 10 K below the highest temperature of the culture medium in the culture vessel at all distances from the interface of BC and gaseous atmosphere within a range of from 0 to 2 cm measured perpendicular to the interface and/or wherein at least during step a) the gaseous atmosphere above the bacterial culture is controlled to be at a relative humidity of at least 70% at all distances from the interface of BC and gaseous atmosphere within a range of from 0 to 2 cm measured perpendicular to the interface.
