12.5 SEM images (×500) of: (a) chitin electrospuns and (b) commercial

chitin microfibres. Chitin nanofibres have diameters of 50–460 nm,

whereas commercial chitin fibres have an average diameter of
8.77 μm.
different industries, in recent years, the design of economical large-scale
production processes has attracted considerable attention (Shoda and
Sugano, 2005). It is clear that the conventional method of microbial cellu-
lose production by static cultivation using sugars such as glucose, fructose,
and sucrose is not applicable to large-scale industrial production because
