Lactic acid bacteria: Micro-organisms able to grow in the absence of available iron and copper
- 151 Downloads
The growth of different species of the genera Lactobacillus, Streptococcus, Pediococcus and Leuconostoc was followed in media in which all available iron and copper was chelated by 2,2′-dipyridyl. None of the species tested was inhibited in its growth. Iron and copper complexation, by means of chemical scavengers, could be a useful method to direct non-axenic lactic fermentations.
