Although pure glycerol has been used as a sole carbon source
for the production of PHB, there is evidence that some Bacillus species
have the ability to produce PHB from crude glycerol. Sindhu
et al. (2011) worked with Bacillus sphaericus NII 0838 and the
PHB accumulation was 31% of cell dry weight. Deepthi et al.
