title: Comment on ''Elucidating the binding efficacy of β-galactosidase on graphene by docking approach and its potential application in galacto-oligosaccharide production".
abstract: In a recent study, Satar et al. (Bioprocess Biosyst Eng 39:807-814, 2016) have reported "the synthesis and characterization of graphene for the immobilization of β-galactosidase for improved galacto-oligosaccharide (GOS) production". There are several issues in this study that must be commented.
