Knowledge of the number and type of heat resistant bacteria in the raw material will assist in calculation of adequate thermal processing to ensure microbial safety of rendered materials. The effectiveness of ultrasound against bacterial spores was investigated by Raso et al. DPA-less mutants were isolated by Halvorson and Swanson 1969 and shown to be heat-sensitive although surprisingly heat-resistant revertants still low in calcium and DPA-free were reported later Hansen et al.
