Data of sensitivity of sorption study deep culture isolates of higher shiitake mushroom used as a modifier acoustic biosensor device are presented in paper. The conditions for preparing biomodifier ; leading to a higher sensitivity of the sensor to an aqueous solution of ammonia were determined. Sensitive elements of piezoelectric resonators were obtained on the basis of mycelial extracts. Sampling of fungal isolates on the criteria values change in resonant frequency and nature of relaxation was conducted. Pure component of resonator response caused by a film of mycelial extract was obtained using fitting simulation procedure . Values of weight of films; modulus of elasticity and viscosity were obtained. It is recommended to use a film shiitake mushroom mycelium extract; aged 14 days; cultivated on synthetic culture medium supplemented with indolyl-3-acetic acid (0;2 mg/L); and extracted with ethanol to determine whether the presence of gaseous ammonia.
