Using physiological, biochemical, morphological identification and 16S rRNA gene sequence analysis methods, the strain CK1 was identified as Bacillus licheniformis. Through extracellular xylanase, CMCase protease assays and evaluations for zearalenone detoxification, the strain CK1 strain was identified to possess good ZEN-detoxifying ability, to be non-hemolytic, non-enterotoxin producing, and displayed high levels of extracellular xylanase, cellulase, and protease activities. Accordingly, Bacillus licheniformis CK1 can be applied as food and feed supplement for bio-detoxification of ZEN.Type: GrantFiled: May 28, 2010Date of Patent: March 26, 2013Assignee: National Taiwan UniversityInventors: Je-Ruei Liu, Ping-Jung Yi

Publication number: 20130045526Abstract: A method for enhancing degradation of petroleum and its derivatives in an object includes placing an object containing petroleum and its derivatives into a compartment of a tank. Oil-eating bacteria is added into or cultivated in the compartment. A suction motor is activated to suck air out of the compartment, such that an air pressure in the compartment is smaller than an air pressure outside of the compartment, forcing the air outside of the compartment to flow into the compartment. A device for enhancing degradation of petroleum and its derivatives in an object includes a tank having a space and an outlet in communication with a bottom of the compartment. The tank includes a top side having an opening in communication with the compartment. A suction motor includes an air inlet and an air outlet. The outlet of the tank is connected to the air inlet of the suction motor.Type: ApplicationFiled: August 15, 2011Publication date: February 21, 2013Inventor: Chitsan Lin
