Specificity of the ricin A chain-ribosome interaction was demonstrated by competition experiments using either ricin A chain or gelonin, another ribosome-inactivating protein having the identical mechanism of ribosome inactivation (26) in a broad spectrum of species including rat and rabbit (12, 26).
Report Abuse. I would say that bread stays fresh in the fridge for about a week. If you are unable to eat alot of bread at one time,then it is best to store your bread in the freezer,because the freezer keeps your bread for a longer period of time than the fridge does! ;-).

Bakery bread typically lasts two to three days beyond its printed best by date. Bread that is beyond its best by date should be well examined before eating, and if any mold is detected, the entire loaf should be discarded. If bread is hardened, but not moldy, it can be made into croutons for later use.
