Based on the low energy QCD Lagrangian and using the wave functions of [SUSF (6) circle times 0(3)](sym). circle times SUe (3) quark model of baryon structure, the strange meson photo-production off the proton is studied. Calculations on cross section for gamma + p -->K+ + Lambda reaction are performed and compared with experimental data. The theoretical predictions are in good agreement with data.
