(iii) signii cantly reducing pain, (iv) accelerating re-epithelialization and the forma-
tion of granulation tissue, and (v) reducing scar formation. h ese microbial cellulose
membranes can be created in any shape and size, which is benei cial for the treatment
of large and dii cult to cover areas of the body (Figure 16.3). h e
in-vivo
tests showed
that microbial cellulose membranes were fully biocompatible and also successfully pro-
tected burn wounds from excessive external l uid loss, thus accelerating the entire pro-
cess of healing [54,55].
h e never-dried microbial cellulose prepared showed unique physical, chemical,
and mechanical properties. h e microbial cellulose displays high crystallinity >60%,
a high water holding capacity up to 200 times its dry mass, a well-developed surface
area comprised of nanoi bers and tensile strength of 92 Mpa. h e materials were very
comfortable, conformable and are transparent. h e transparency of the never-dried

A never-dried microbial cellulose membrane shows remarkable conformability to the
various body contours, maintains a most environment, and signii cantly reduces pain (image courtesy of
