      abstract     = {We have synthesized nano-structured silica–Escherichia
                      coli composite micro-granules by spray drying of mixed
                      suspension of silica and E. coli through evaporation-induced
                      assembly. Synthesized micro-granules were subjected to
                      calcination in order to form shape-matched macro-pores by
                      removing the bacterial cells. The optimization of
                      calcination temperature is crucial because calcination
                      process leads to two contrasting effects, namely, (i)
                      removal of E. coli from the granules and (ii) alteration of
                      mesoscopic structure in the silica network. We have used
                      small-angle neutron scattering and thermo-gravimetric
                      analysis to determine the optimum temperature for
                      calcination of these granules. It was found that calcination
                      in the temperature range of 200 °C to 400 °C removes the
                      cells without significant alteration of the nano-structured
                      silica network. However, beyond 500 °C, calcination results
                      significant coalescence between the silica particles.
                      Calcination at 600 °C eventually collapses the meso-pore
                      network of silica interstices.},
