CRM-LPN.00107BL and CRM-LAN.00106BL are designed for media control and are fully compliant with ISO 11731. The CRM-LPN.00107BL is not suitable for process control because the strain is unable to survive heat and acid treatment. Therefore a robust wild strain of Legionella pneumophila is used in the CRM-LPN.BH. This strain is still cultivable after heat and acid treatment and, thus, very suitable for process control of all the methods variety in ISO 11731.
