Inactivation ofMycobacterium aviumssp.paratuberculosisin milk by UV treatment

Inactivation of Mycobacterium avium ssp. paratuberculosis in milk by UV treatment.

AIMS To determine the effect of UV radiation on the viability of two strains of Mycobacterium avium ssp. paratuberculosis (Map) inoculated into milk. METHODS AND RESULTS Mycobacterium avium ssp. paratuberculosis in a ultra heat treated milk matrix was subjected to increasing doses of UV-C radiation from 0 to 1836 mJ ml(-1) using a pilot-scale UV reactor (20 l capacity). Survival of Map was mo...

UV light inactivation of Mycobacterium avium subsp. paratuberculosis in milk as assessed by FASTPlaqueTB phage assay and culture.

UV light inactivation of Mycobacterium avium subsp. paratuberculosis in Middlebrook 7H9 broth and whole and semiskim milk was investigated using a laboratory-scale UV machine that incorporated static mixers within UV-penetrable pipes. UV treatment proved to be less effective in killing M. avium subsp. paratuberculosis suspended in milk (0.5- to 1.0-log(10) reduction per 1,000 mJ/ml) than that s...

Inactivation of Bacillus subtilis Spores in Soybean Milk by Radio-Frequency Flash Heating Treatment

Heat-resistant microorganisms such as Bacillus subtilis spores derived from soil may exist in soybean milk and can reduce the shelf life of tofu produced from conventional processing of soybean milk. Conventional high-temperature, long-time heat processing of soybean milk sufficiently inactivates spores of this organism. An apparatus to pasteurize soybean milk using radio-frequency flash heatin...
