•SBCSs with DS 0.10–1.50 were prepared homogeneously with SO3/Py in DMAc/LiCl.•SBCSs were characterized with FTIR, NMR, EA, XRD, GPC, and TGA.•Bacterial cellulose expresses higher reactivity than microcrystal cellulose.•Cellulose sulfates with DS>0.31 were soluble in deionized water.•The present...
