Multi-phase bacterially-synthesized-nanocellulose biomaterials and method for producing the same

Abstract

Multiphase biomaterials are provided which are based on bacterially synthesized nanocellulose (BNC) including at least two different bacterial cellulose networks. To this end, a culture median is inoculated with at least two different cellulose-producing bacterial strains.

1 . Multi-phase biomaterials, comprising bacterially synthesized nanocellolose (BNC) comprised of at least two different bacterial cellulose networks. 
     
     
         2 . Multi-phase biomaterials according to  claim 1 , wherein the at least two different bacterial cellulose networks differ in their molecular structure. 
     
     
         3 . Multi-phase biomaterials according to  claim 1 , wherein the at least two different bacterial cellulose networks differ in their supra-molecular structure. 
     
     
         4 . Multi-phase biomaterials according to  claim 1 , wherein the at least two different bacterial cellulose networks are formed as a combined homogeneous phase system. 
     
     
         5 . Multi-phase biomaterials according to  claim 1 , wherein the at least two different bacterial cellulose networks are formed as a layered phase system comprising firmly combined separate single phases. 
     
     
         6 . Multi-phase biomaterials according to  claim 1 , wherein the at least two different bacterial cellulose networks are formed as a layered phase system comprising at least one combined homogeneous phase and at least one single phase. 
     
     
         7 . Method for producing multi-phase biomaterials comprised of bacterially synthesized nanocellulose (BNC), comprising inoculating a culture medium with at least two different cellulose-producing bacterial strains, which have been commonly or separately prepared, thereby to synthesize BNC comprised of a plurality of different bacterial cellulose networks wherein BNC structure and BNC properties of the multi-phase biomaterials are predetermined by selection of the at least two different bacterial strains, by their preparation and inoculation and by selection of conditions of the synthesis. 
     
     
         8 . Method according to  claim 7 , wherein the at least two different bacterial cellulose networks are prepared independently from each other and subsequently combined and commonly synthesized. 
     
     
         9 . Method according to  claim 7 , wherein the at least two different bacterial cellulose networks are combined for the common synthesis already before the inoculation.
