摘要：
The production of a spray-dried bacteriocin lacticin 3147 powder is described. The powder is shown to have effective anti-microbial activity in a range of foodstuffs, namely infant milk formulations, powdered soup, yoghurt and cottage cheese. Increased anti-microbial activity was demonstrated when the lacticin 3147 powder was used in conjunction with increased hydrostatic pressure. The process comprises: inoculating a medium with a lacticin 3147-producing strain of bacteria, fermenting the inoculated medium, adjusting the pH of the fermentation to 6.3-6.7, inactivating the bacterial fermentate and evaporating the fermentate.
