We study the possibility of achieving a low unification scale in a grand unification scheme based on the gauge group SU(16). Baryon number symmetry being an explicit local gauge symmetry here, the gauge-boson-mediated proton decay is absent. We present in detail a number of symmetry-breaking patterns and the Higgs field representations giving rise to the desired symmetry breakings and identify one chain giving low-energy unification. These Higgs field representations are constructed in such a way that Higgs-boson-mediated proton decay is absent. At the end we indicate the very rich low-energy physics obtainable from this model which includes quark-lepton ununified symmetry and chiral color symmetry. In brief some phenomenological implications are also studied.
