An initial decrease in
pH was noticed in samples and that could be due to
the ability of the strain B. subtilis to initially use sugar
as substrates for their growth19 and simultaneously they
produce acid via pyruvate.20
chitin and their concentrations were standardized. Chitin was converted to chitosan by N-deacetylation and the properties
of chitin and chitosan were studied. FTIR spectral analysis of chitin and chitosan prepared by the process was carried out and compared
with spectra of commercially available samples.
