Bacterial cellulose biodegradation

U.S. Pat. No. 6,274,652 [127] discloses a biodegradable composite material comprising bacterial cellulose in a powdery state and a polymeric material such as poly-hydroxybutyrate, polyhydroxyvalerate, polycaprolactone, polybutylenesuccinate, polyethylenesuccinate, polylactic acid, polyvinylalcohol, cellulose acetate, starch, and other biodegradable polymers.

Although bacterial cellulose alone shows a good biocompatibility, hybrids, such as the polyvinyl alcohol-bacterial cellulose listed in Table 5.2, might not be biodegradable per se, and need to be tested. However, the formation of hybrids is an essential requirement for being able to exploit the whole scope of possibilities connected to a drug delivery approach via vesicles. Formation of hybrids allows for the easier construction of... 

Bacterial cellulose (BC) is biodegradable polyester produced by specific genera of bacteria Acetobacter, Rhizobium, Agrobacterium) and certain algae [33,34]. The chemical structure of BC is similar to that of plant cellulose, but BC possesses considerably superior physical, mechanical, and biological properties when compared to plant cellulose [35]. BC is chemically pure and does not contain any impurities such as lignin and hemicelluloses that are associated with plant cellulose. It exhibits a fibrous network... 

The chitosan-modified bacterial cellulose, characterised by unique properties, i.e. bioactivity, biodegradability, biocompatibility, no toxicity and non-allergic action, coimected with good mechanical tenacity, has been found to be a great material for biomedical applications such as dressings for wound healing. ...
