The
equivalent of cellulose in other plants (e.g. wood formed from lignin
fibres in trees), but made by bacteria. So just like plant cells have a
cellulose shell to give them protection and structural integrity,
bacteria have something similar. I ended up on this page because I was
reading on a homemade tools group about how someone had used the stuff
in the same way leather is used, for strapping two parts together.
Bacterial cellulose has certain desirable characteristics such as
greater tensile strength than plant cellulose and large hydrophilicity
(attraction to water) and so may be useful in biomedical applications.More info in this Wikipedia article.
