Abstract
The invention relates to a method for converting nitrates to nitrites and to specific compositions of bacteria belonging to the Staphylococcus vitulinus species optionally in association with lactic acid bacteria such as Lactococcus genus or Pediococcus genus and their use for developing the red color of a food product containing myoglobin.
Claims22
Method for converting nitrates to nitrites, comprising the step of converting nitrates to nitrites by bacteria belonging to the Staphylococcus vitulinus specie having nitrate reductase activity (NRA), of in the presence of:
- lactic acid bacteria, at a pH comprised between 5.2 and 9 and/or
- a medium which has been in contact with lactic acid bacteria and is substantially free of bacteria, at a pH comprised between 5.2 and 9.
2-4. (canceled)
Composition comprising:
- a) bacteria belonging to the Staphylococcus vitulinus specie having NRA and
- b) lactic acid bacteria and/or a medium that has been in contact with lactic acid bacteria and that is substantially free of bacteria.

(canceled)
Method for increasing the nitrate reductase activity (NRA) of bacteria belonging to the Staphylococcus vitulinus specie comprising the step of incubating said bacteria belonging to the Staphylococcus vitulinus specie in the presence of nitrates and lactic bacteria or a medium which has been in contact with lactic bacteria and is substantially free of bacteria at a pH comprised between 5.2 and 9.
