BC production comparison. Enterobacter sp. FY-07 and FY-0701 were streaked on fermentation media containing glucose (a and c) or glycerol (b and d) as the sole carbon source. Colonies of FY-07 (a and b) or FY-0701 (c and d) were selected to detect BC production by SEM observation. The magnification is 20,000×. Red triangles indicate parts of BC microfiber.
