Low Intensity Pulsed Ultrasound (LIPUS) is a form of mechanical energy which can penetrate living cells in the form of acoustic pressure waves. This energy, generated by a novel programmable LIPUS device, has been shown in past studies to stimulate growth in tooth initials, stem cells and fungal mycelia. In vitro studies have demonstrated enhanced production of Active Pharmaceutical Ingredients (APIs) in submerged cultures of fungi. This proof-of-concept design has the potential for use in industrial fermentation processes for enhancement of production of products such as drugs (APIs) by microbial cultures. In a cooperative effort with Apotex Fermentation Inc. (AFI), IntelligentNano Inc., the University of Alberta (UofA) and the Alberta Research Council (ARC), LIPUS transducers will be modified for use in conventional fermentation equipment with the intention of testing the applicability of the technology for commercial fermentation processes. This innovative technology has the potential for development of customized, programmable LIPUS transducers to enhance fermentation processes in the pharmaceutical industry and in other fermentation-based processes. The LIPUS technology holds the potential of giving companies like Apotex a competitive edge in the ever-changing global pharmaceutical marketplace by increasing productivity.
