Abstract:  Bacterial endospores are the most resistant living structures, known. Their high degree of resistance to many treatments (including heat and UV) is governed by their unique spore structure, these structure characteristics make spore survive pasteurization in raw milk. Thus, the presence of psychrotrophic, mesophilic and thermophilic Bacillus spp from bulk raw milk should be taken as one of the detection items, in order to well judge the quality of raw milk. This paper summarized all kinds of detection methods on spore, to provide a base for the fast detection of raw milk spore.

Key words: spore, raw milk, detection, dipicolinic acid
