Lactic Acid Bacteria as Starter-Cultures for Cheese Processing: Past, Present and Future Developments

Strain-to-strain differences within lactic and propionic acid bacteria species strongly impact the properties of cheese-A review

Lactic acid bacteria (LAB) and propionic acid bacteria (PAB) are widely used in the manufacture of cheeses and other fermented dairy products. Bacterial species used as starters are mainly chosen according to their intrinsic properties: the milk acidifying capacity for LAB starters and the aromatizing properties of PAB, for example. Beyond the general characteristics of a bacterial species, man...

Threonineserine antagonism in some lactic acid bacteria.

Various investigators have reported antagonism between amino acids in the nutritional requirements of microorganisms. Snell and Guirard (1) have reported the inhibitory effect of glycine, serine, p-alanine, and threonine on the utilization of alanine. Gladstone (2), using BaciZZus anthrucis, found that certain amino acids prevented growth when added singly to a medium capable of supporting grow...
