1. A biosensor comprising a recombinant FAD-conjugated glucose dehydrogenase, wherein the recombinant FAD-conjugated glucose dehydrogenase is selected from:

  • (a) a polypeptide which comprises the amino acid sequence represented by SEQ ID NO;

    1; and

    (b) a polypeptide which comprises an amino acid sequence having a homology of 90% or more to the amino acid sequence (a) and has an FAD-conjugated glucose dehydrogenase activity;

    wherein the recombinant FAD-conjugated glucose dehydrogenase has a value of enzymatic activity for maltose of 10% or less with a value of enzymatic activity for D-glucose taken as 100%; and

    wherein the biosensor is capable of detecting glucose.
